RFco.axiAL_ CONNECTORS INFO RMATION The HRM (Hirose Radio Miniature) series are connectors of the SMA (Sub-Miniature Type A) type, prescribed in MIL-C-39012. We developed them in 1967, for the first time in Japan, thanks to our companys outstanding technology. Since then, their high reliability has been recognized, and we have a sales record of more than 6 million thus far. Uses The HRM series is suitable for in- unit wiring in wired and wireless communications equipment, broad- casting equipment, radar equipment and electronic measuring instru- ments, for connections between units, and for input/output ter- minals of equipment components. They display their effects especially in set designs subject to severe requirements, such as those which operate in a frequency band above the band and which also have transmission. 1. Outstanding performance characteristics. The matters which most require consideration in matching the impedance of coaxial | 1 connectors are these: How are we to reduce the discontinuous capacitance caused Characteristic by dimensional discontinuities on the transmission channel (the differences in level features provided for supporting the center contacts or the dielectric materials), and how are we to correct the discontinuous capacitance which does occur? In this respect, the high-frequency performance characteristics of the HRM series are good because there are small differences in level in the transmission channel, and the discontinuous capacitance which does occur because of the differences in level is corrected by a unique technique. Moreover, the series also has mechanically stable performance characteristics because the center contacts and dielectric materials have secure fastening structure. 2. They are compact in size, lightweight and sturdy. The receptacle flanges are square in shape, measuring 12.7mm on each side. Their area being about one-half that of the BNC series and about one-fourth that of the S series, they are most suitable for high-density mounting. Moreover, their weights are greatly reduced (a standard receptacle weighs only about 3 grams). Even though they are compact and lightweight, their durability is no lower than that of other types, because they use stainless-steel shells. 3. They have high quality and reliability. The HRM series is manufactured under a system of thorough quality control from the raw materials to the shipped product. In addition to the highest manufacturing quality, they also have high reliability, and not a single faulty unit has ever occurred at the end-user stage with a service record exceeding 6 million units. 4. There are many varieties. An extensive expansion of the varieties has been carried out recently, including provid- ing the S type for al! varieties and adding airtight connectors and connectors for .085-inch semi-rigid cables. As a result, clients can now select products more freely than was possible before. 87RF co.axiAL CONNECTORS Standard cables Types The following are the standard cables of the HRM series: *These cables differ from the 3D-2W 3D-2W (Irrax cables) * in the JIS standards and the NTT specifications. Please purchase from RG-142B/U Sumitomo Electric Industries, Ltd. cables having the dimensions shown on P.110. .141-inch semi-rigid cables Semi-rigid cables | (UT-141, UT-141A, UT-141AA etc.) .085-inch semi-rigid cables (UT-85, UT-85C etc.) The standard cable dimensions are listed on P.110. Flexible cables 1. Classification by function Functionally, the cables are classified into six types. The following is the configuration of their names. HRM XXX XXX Additional number (A number of 1 ~ 3 digits is used. Name of Numbers are assigned to some products and not to others.) type 100 ~ 199 (Connectors for semi-rigid cables) 200 ~ 299 (Connectors for Flexible cables) 300 ~ 399 (Receptacles) 400 ~ 499 (Plug receptacles) 500 ~ 599 (Adapters) 600 ~ 699 (Accessories) 2. Classification by surface treatment Products having the same structure, shape and dimensions may have different surface treatments of their armor (shell). There are gold-plated products (gold-plated type) and passivated products (S type). Those of the S type have the letter S attached at the end of their part number. Example 1 HRM301 HEM=3018 Gold-plated type S type Exampel 2 HRM40012 HRM400--12S Gold-plated type S type Technical explanations of the S-type products and of passivation are given on p. 990. 3. Airtight type Airtight products with hermetic seals are also available. All airtight products are of the gold-plated type. Air tight types are not available in the S type. Products of the airtight type have the letter H attached at the end of their part number.

Connectors for semi-rigid cables HRM- 100~ 199 Connectors for semi-rigid cables match two types of cables: .141-inch and .085-inch semi-rigid cables. Use the .141-inch cables in order to obtain the V.S.W.R. listed on P.90. The .085-inch cables, which have good flexibility, are suitable when high-density wiring is to be used inside the set. In this case, the V.S.W.R. value will be higher than with the .141-inch cables.

Passivation refers to a type of surface treatment in which the outer surface of the stainless steel is etched with hydrofluoric acid in order to reduce the number of iron particles on it. This forms an oxide film which is thin enough to exert no influence on the electrical conductivity. The cor- rosion resistance of the stainless steel can be enhanced by performing this treatment. The original goal in developing the S$ type was to prevent corrosion. That is, in com- binations in which the surface treatment of the armor parts is gold plating and the material of the set panel is aluminum, the potential difference between them is rather high (0.9V), and there is the danger that electrolytic corrosion may be induced under certain environmental conditions. As a countermeasure to prevent this, the S type is used, in which the potential difference between the stainless steel and aluminum is relatively low (0.4V). Not only does the $ type have high corrosion resistance, but it has also been proved to have corrosion resistance superior to that of the gold-plated type by acceleration tests with salt-water spraying and by tests in which samples were left for 5000 hours in places where there was much sulfurous acid gas. There are also other advantages. For example, in the gold-plated type, powder from the gold plating is deposited on the surfaces of the coupling parts, but this drawback is absent in the S type. In addi- tion, since expensive gold is not used, the S type can be provided at a lower price than the gold-plated type. In order to make more effective use of these advantages, it is scheduled in the future to give priority to the S type over the gold-plated type and to make it the standard product. Moreover, although passivation is, as a general rule, the surface treatment of the S type, other treatments may be used as special exceptions in the following cases: (1) In the L-bent type, nickel plating is used because the surface of stainless steel is highly discolored by the heat applied during brazing. In this case, the potential difference relative to the aluminum will be 0.6V. (2) In connectors for semi-rigid cables {HRM-100~199), gold plating is used in pro- ducts in which the outer conductors of the cables are soldered (for example, the shell of HRM-101S) in consideration of the soldering properties. 1. Frequency Range The cut-off frequency of the coaxial transmission path can be found from the follow- ing expression: f _ 3x10" (Hz) d, = Outer diameter of center contact (unit: mm) CUT at (d; + ds)/2 d, = Inner diameter of outer contact (unit: mm) The cut-off frequency of the HRM series calculated by this expression is 35.5GHz. However, this value is purely a theoretical value in an ideal transmission path. If we take into account the voltage standing wave ratio, the upper limit of the frequency that can be used industrially will be about 18GHz. At the present time, the upper limit of the guaranteed frequency of the HRM series is 12.4GHz, lower than 18GHz. In certain products, satisfactory results have been obtained with frequencies of up to 18GHz as the typical value. Clients who plan to use frequencies higher than 12.4GHz are requested to inquire.PRFco-AXIAL CONNECTORS 2. Insertion Loss The insertion loss of the HRM series can be found from the following expression: Loss <0.03-/ f (GHz) (dB) The insertion loss at 12.4GHz calculated by this expression is 0.1dB. That is, the insertion loss of the HRM series will be 0.1dB or less throughout the entire guaranteed band. This value has been confirmed. 3. High-Frequency Loss The high-frequency loss of the HRM series has values of 100dB or more within the range of the guaranteed frequencies under the following two conditions: that the couplings are tightened with the prescribed torque, and that the sets and connectors are thoroughly fastened with machine screws. 4. Performance properties of the S Type In the gold-plated type there will be little conductor loss because the electromagnetic field will be concentrated at the gold-plated parts because of the skin effect. However, in the S type the conductor loss will be larger because the electromagnetic field will be distributed in the stainless-steel parts. However, it will be nearly negligible since the transmission path is short (the length of the transmission path is 15.2mm when a typical receptacle and a plug receptacle are coupled together). The skin will be rough as a result of the passivation, but this has no influence at all on the performance characteristics because the roughness is far less than the finishing precision of the cutting. Permissible 1. Average Power Electric Power The permissible average power of the connectors cannot be determined uncondi- tionally because a number of indeterminate conditions must be included, such as the frequency, the voltage standing wave ratio, the heat radiated by the device, the modu- lation ratio, etc. However, the value 50// f (GHz) (W) can be applied as a tentative yardstick value for the HRM series. Even this value cannot be said to be an absolute yardstick on account of factors such as the heat radiation conditions. In actual prac- tice, 50W has been applied at 6GHz. 2. Peak Power The peak power of the connectors is determined by their breakdown voltage. In the HRM series, the peak power is about 20kW. Note that the values of both the average power and the peak power are values appli- cable under the following conditions: (1) There is to be a state of normal temperature, normal humidity, and normal pressure. (2) In products to which cables are connected, priority is to be given to the permis- sible power values of the cables. Even in cases where the cables have a higher permissible power than the connectors, there are to be no defects in the wiring connections. (3) There is to be no metal powder on the coupling surfaces of the connectors. Care must be taken especially in the gold-plated type, since there is a tendency for meta! powder to be deposited on the coupling surfaces of this type. 109slateasdas FRFCo-AXIAL CONNECTORS Tightening Torque Suitable values for the tightening torque of couplings of the HRM series are 6 ~ of Couplings 10kg-cm. As for which values ought to be chosen for use within this range, the most suitable tightening torque is 6kg-cm when no particular vibrations are applied except during transport, or 10kg-cm in environments where vibrations are applied. The following is the basis on which the range of 6 ~ 10kg-cm was established. First, in vibration tests simulating the vibration conditions that occur during transport, it has been confirmed that loosening does not occur when the couplings are tightened with a torque of 3kg-cm. Thus, allowing a safety factor of 2 times, the value was set at 6kg-cm. The upper limit value of 10kg-cm was established on the basis of the amount of dimensional changes in the outer diameter of the male coupling part, which is 4.56@ *9-02. Thus, the tightening torque of the couplings of the HRM series has a narrow range, and problems will occur if they are tightened with a torque outside of this range. Consequently, we recommend that you use an 8mm x 6kg-cm or 8mm x 10kg-cm torque wrench when tightening the couplings.

Fig.(19) LSS 22 222) Addendum When connectors of the HRM series are to be connected and used with semi-rigid cables, their performance pro- perties, like those of other types of connectors, will be governed largely by the quality of the wiring connection work. The same thing can be said with reference to connec- tion of the wiring of flexible cables as well. However, in cases where even better performance characteristics are needed, the precautions described above must be observed. When semi-rigid cables are to be bent in use, tools like those shown in Fig. (20) (HRM-T-5, 9) can be used to bend ther with radii of curvature of 6R, 8R, 10R or 12R, respective- ly. If they are to be used ina spiral shape, the rear surfaces of (HRM-T-5, 9) are used. This is shown in the photograph. Fig. (21} shows the V.S.W.R. data for semi-rigid cables that are connected in bent shape as shown in the photograph and for those that are connected straight. It is clear that there are no large differences in the characteristic features.

Note 3: In the case of cables using Irrax insulation, such as 3D-2W, be careful to perform the soldering speedily so that the tip will not dissolve as a result of the heat during soldering. Note 4: The build-up of solder after soldering must be finished uniformly on the circumference. To check the strength of the soldering, pull the male contact with a force of about 1kg (2.47 Ib.). Note 5: Be careful not to allow a gap to be produced be- tween the insulation and the contact after soldering. Note 6: Be careful not to allow the male contact to be sol- dered in a bent position towards the center con- ductor of the cable. Note 7: It is desirable to use a soldering iron of about 20 ~ 30W.

(Refer to Fig. (31).) (3) Solder the center conductor and crimp the ferrule (sleeva). Fit HRM-T-1 (the locator) in place in order to prevent the connector male contact and insulation from mov- ing, and hold it firmly in place with a vice. Remove the connector cover and insert the cable through the cord inlet, as shown in Fig. (32), aligning the center conductor of the cable with the groove at the connector male contact. iii) Solder the center conductor of the cable to the male contact at the position where the cable insulation strikes against the male contact. iv) After the soldering, check to make sure whether or not it has been carried out perfectly by pulling the cable with a force of about 1kg of weight. Next insert the ferrule (sleeve) over the outer conductor of the cable until it strikes against the uneven part of the shell, and crimp it in a hexagonal shape with HRN-T-4. Note 1: Perform the soldering carefully, making sure not to deposit solder on the outer surface of the male contact of the connector. Note 2: It is desirable to use a soldering iron of about 20 ~ 30W. Its tip must be narrowed so as to make the work easy. Note 3: Soils on the inside of the connector produced as a result of soldering should be washed off with thinner or the like in order to prevent the occur- rence of faulty insulation or inadequate withstand voltage. Note 4: Crimping of the ferrule (sleeve) is performed first on the cable side and next on the connector side. (Be careful about the order; if the wrong order is followed, the clamping force will be reduced: by one half.)
