The reference plane can be described as being at the center of both the gate and drain pads. S and noise parameters are measured with a 50 ohm microstrip test fixture made with a 0.010" thickness aluminum substrate. Both source leads are connected directly to ground via a 0.010" thickness metal rib which provides a very low inductance path to ground for both source leads. The inductance associated with the addition of printed circuit board plated through holes and source bypass capacitors must be added to the computer circuit simulation to properly model the effect of grounding the source leads in a typical amplifier design. Reference Plane Source Pin 3 Drain Pin 4 Sx Source Pin 1 Gate Pin 2 Microstrip Transmission Lines Figure 20. Noise Parameter Applications Information The Fmin values are based on a set of 16 noise figure measurements made at 16 different impedances using an ATN NP5 test system. From these measurements, a true Fmin is calculated. Fmin represents the true minimum noise figure of the device when the device is presented with an impedance matching network that transforms the 10 source impedance, typically 50, to an impedance represented by the reflection coefficient o. The designer must design a matching network that will present o to the device with minimal associated circuit losses. The noise figure of the completed amplifier is equal to the noise figure of the device plus the losses of the matching network preceding the device. The noise figure of the device is equal to Fmin only when the device is presented with o. If the reflection coefficient of the matching network is other than o, then the noise figure of the device will be greater than Fmin based on the following equation. NF = Fmin + 4 Rn |s - o | 2 Zo (|1 + o| 2) (1 - |s| 2) Where Rn/Zo is the normalized noise resistance, o is the optimum reflection coefficient required to produce Fmin and s is the reflection coefficient of the source impedance actually presented to the device. The losses of the matching networks are non-zero and they will also add to the noise figure of the device creating a higher amplifier noise figure. The losses of the matching networks are related to the Q of the components and associated printed circuit board loss. o is typically fairly low at higher frequencies and increases as frequency is lowered. Larger gate width devices will typically have a lower o as compared to narrower gate width devices. Typically for FETs , the higher o usually infers that an impedance much higher than 50 is required for the device to produce Fmin. At VHF frequencies and even lower L Band frequencies, the required impedance can be in the vicinity of several thousand ohms. Matching to such a high impedance requires very hi-Q components in order to minimize circuit losses. As an example at 900 MHz, when airwwound coils (Q>100)are used for matching networks, the loss can still be up to 0.25 dB which will add directly to the noise figure of the device. Using muiltilayer molded inductors with Qs in the 30 to 50 range results in additional loss over the airwound coil. Losses as high as 0.5 dB or greater add to the typical 0.15 dB Fmin of the device creating an amplifier noise figure of nearly 0.65 dB. SMT Assembly The package can be soldered using either lead-bearing or leadfree alloys (higher peak temperatures). Reliable assembly of surface mount components is a complex process that involves many material, process, and equipment factors, including: method of heating (e.g. IR or vapor phase reflow, wave soldering, etc) circuit board material, conductor thickness and pattern, type of solder alloy, and the thermal conductivity and thermal mass of components. Components with a low mass, such as the Minipak 1412 package, will reach solder reflow temperatures faster than those with a greater mass. The recommended leaded solder time-temperature profile is shown in Figure 21. This profile is representative of an IR reflow type of surface mount assembly process. After ramping up from room temperature, the circuit board with components attached to it (held in place with solder paste) passes through one or more preheat zones. The preheat zones increase the temperature of the board and components to prevent thermal shock and begin evaporating solvents from the solder paste. The reflow zone briefly elevates the temperature sufficiently to produce a reflow of the solder. The recommended lead-free reflow profile is shown in Figure 22. The rates of change of temperature for the ramp-up and cooldown zones are chosen to be low enough to not cause deformation of board or damage to components due to thermal shock. The maximum temperature in the reflow zone (Tmax) should not exceed 235C for leaded solder. Electrostatic Sensitivity FETs and RFICs are electrostatic discharge (ESD) sensitive devices. Agilent devices are manufactured using a very robust and reliable PHEMT process, however, permanent damage may occur to these devices if they are subjected to high-energy electrostatic discharges. Electrostatic charges as high as several thousand volts (which readily accumulate on the human body and on test equipment) can discharge without detection and may result in failure or degradation in performance and reliability. These parameters are typical for a surface mount assembly process for the ATF-541M4. As a general guideline, the circuit board and components should only be exposed to the minimum temperatures and times the necessary to achieve a uniform reflow of solder. Electronic devices may be subjected to ESD damage in any of the following areas: 250 TMAX TEMPERATURE (C) 200 150 Reflow Zone 100 Preheat Zone Cool Down Zone 50 0 0 60 120 180 240 * * * * Storage & handling Inspection Assembly & testing In-circuit use The ATF-541M4 is an ESD Class 1 device. Therefore, proper ESD precautions are recommended when handling, inspecting, testing, and assembling these devices to avoid damage. Any user-accessible points in wireless equipment (e.g. antenna or battery terminals) provide an opportunity for ESD damage. For circuit applications in which the ATF-541M4 is used as an input or output stage with close coupling to an external antenna, the device should be protected from high voltage spikes due to human contact with the antenna. A good practice, illustrated in Figure 23, is to place a shunt inductor or RF choke at the antenna connection to protect the receiver and transmitter circuits. It is often advantageous to integrate the RF choke into the design of the diplexer or T/R switch control circuitry. 300 TIME (seconds) Figure 21.

As opposed to a typical depletion mode PHEMT where the gate must be made negative with respect to the source for proper operation, an enhancement mode PHEMT requires that the gate be made more positive than the source for normal operation. Therefore a negative power supply voltage is not required for an enhancement mode device. Biasing an enhancement mode PHEMT is much like biasing the typical bipolar junction transistor. Instead of a 0.7V base to emitter voltage, the ATF-541M4 enhancement mode PHEMT requires a nominal 0.58V potential between the gate and source for a nominal drain current of 60 mA. Matching Networks The techniques for impedance matching an enhancement mode device are very similar to those for matching a depletion mode device. The only difference is in the method of supplying gate bias. S and Noise Parameters for various bias conditions are listed in this data sheet. The circuit shown in Figure 1 shows a typical LNA circuit normally used for 900 and 1900 MHz applications. (Consult the Agilent Technologies web site for application notes covering specific designs and applications). High pass impedance matching networks consisting of L1/C1 and L4/C4 provide the appropriate match for noise figure, gain, S11 and S22. The high pass structure also provides low frequency gain reduction which can be beneficial from the standpoint of improving out-of-band rejection. 12 Capacitors C2 and C5 provide a low impedance in-band RF bypass for the matching networks. Resistors R3 and R4 provide a very important low frequency termination for the device. The resistive termination improves low frequency stability. Capacitors C3 and C6 provide the RF bypass for resistors R3 and R4. Their value should be chosen carefully as C3 and C6 also provide a termination for low frequency mixing products. These mixing products are as a result of two or more in-band signals mixing and producing third order in-band distortion products. The low frequency or difference mixing products are terminated by C3 and C6. For best suppression of third order distortion products based on the CDMA 1.25 MHz signal spacing, C3 and C6 should be 0.1 uF in value. Smaller values of capacitance will not suppress the generation of the 1.25 MHz difference signal and as a result will show up as poorer two tone IP3 results. C4 C1 INPUT Q1 Zo L1 L4 L2 R4 OUTPUT Zo L3 C2 C5 R3 R5 R1 C3 C6 R2 Whereas a depletion mode PHEMT pulls maximum drain current when Vgs = 0V, an enhancement mode PHEMT pulls only a small amount of leakage current when Vgs = 0V. Only when Vgs is increased above Vto, the device threshold voltage, will drain current start to flow. At a Vds of 3V and a nominal Vgs of 0.58V, the drain current Id will be approximately 60 mA. The data sheet suggests a minimum and maximum Vgs over which the desired amount of drain current will be achieved. It is also important to note that if the gate terminal is left open circuited, the device will pull some amount of drain current due to leakage current creating a voltage differential between the gate and source terminals. Passive Biasing Passive biasing of the ATF-541M4 is accomplished by the use of a voltage divider consisting of R1 and R2 connected to the gate of the device. The voltage for the divider is derived from the drain voltage. This provides a form of voltage feedback (through the use of R3) to help keep drain current constant. Resistor R5 (approximately 10K) is added to limit the gate current of enhancement mode devices such as the ATF-541M4. This is especially important when the device is driven to P1dB or Psat. Vdd Figure 1. Typical ATF-541M4 LNA with Passive Biasing. Bias Networks One of the major advantages of the enhancement mode technology is that it allows the designer to be able to dc ground the source leads and then merely apply a positive voltage on the gate to set the desired amount of quiescent drain current Id. Resistor R3 is calculated based on desired Vds , Ids and available power supply voltage. R3 = VDD - Vds Ids + IBB (1) p VDD is the power supply voltage. Vds is the device drain to source voltage. Ids is the desired drain current. IBB is the current flowing through the R1/R2 resistor voltage divider network. The value of resistors R1 and R2 are calculated with the following formulas R1 = R2 = Vgs IBB (2) p (Vds - Vgs) R1 Vgs (3) p Example Circuit VDD = 5 V Vds = 3 V Ids = 60 mA Vgs = 0.58 V Choose IBB to be at least 10X the maximum expected gate leakage current. IBB was chosen to be 2 mA for this example. Using equations (1), (2), and (3) the resistors are calculated as follows R1 = 290 R2 = 1210 R3 = 32.3 Active Bias Active biasing provides a means of keeping the quiescent bias point constant over temperature and constant over lot to lot variations in device dc performance. The advantage of the active biasing of an enhancement mode PHEMT versus a depletion mode PHEMT is that a negative power source is not required. The techniques of active biasing an enhancement mode device are very similar to those used to bias a bipolar junction transistor.

INPUT R1 and R2 provide a constant voltage source at the base of a PNP transistor at Q2. The constant voltage at the base of Q2 is raised by 0.7 volts at the emitter. The constant emitter voltage plus the regulated VDD supply are present across resistor R3. Constant voltage across R3 provides a constant current supply for the drain current. Resistors R1 and R2 are used to set the desired Vds. The combined series value of these resistors also sets the amount of extra current consumed by the bias network. The equations that describe the circuit's operation are as follows. ( VDD V - VB 1 + DD VB 9 ) (5A) p Example Circuit VDD = 5 V Vds = 3 V Ids = 60 mA R4 = 10 VBE = 0.7 V Equation (1) calculates the required voltage at the emitter of the PNP transistor based on desired Vds and Ids through resistor R4 to be 3.6V. Equation (2) calculates the value of resistor R3 which determines the drain current Ids. In the example R3=23.3. Equation (3) calculates the voltage required at the junction of resistors R1 and R2. This voltage plus the step-up of the base emitter junction determines the regulated Vds. Equations (4) and (5) are solved simultaneously to determine the value of resistors R1 and R2. In the example R1=1450 and R2 =1050. Resistor R7 is chosen to be 1 k. This resistor keeps a small amount of current flowing through Q2 to help maintain bias stability. R6 is chosen to be 10 K. This value of resistance is high enough to limit Q1 gate current in the presence of high RF drive levels as experienced when Q1 is driven to the P1dB gain compression point. C7 provides a low frequency bypass to keep noise from Q2 effecting the operation of Q1. C7 is typically 0.1 F. Maximum Suggested Gate Current The maximum suggested gate current for the ATF-541M4 is 2 mA. Incorporating resistor R5 in the passive bias network or resistor R6 in the active bias network safely limits gate current to 500 A at P1dB drive levels. In order to minimize component count in the passive biased amplifier circuit, the 3 resistor bias circuit consisting of R1, R2, and R5 can be simplified if desired. R5 can be removed if R1 is replaced with a 4.7K resistor and if R2 is replaced with a 27K resistor. This combination should limit gate current to a safe level. PCB Layout A suggested PCB pad print for the miniature, Minipak 1412 package used by the ATF-541M4 is shown in Figure 3. 0.4 0.016 This pad print provides allowance for package placement by automated assembly equipment without adding excessive parasitics that could impair the high frequency performance of the ATF-541M4.
