APPLICATIONS Test instrumentation Microwave radios and very small aperture terminals (VSATs) Military radios, radars, and electronic counter measures (ECMs) Broadband telecommunications systems GENERAL DESCRIPTION The HMC641ALP4E is a general-purpose, nonreflective, singlepole, four-throw (SP4T) switch manufactured using a gallium arsenide (GaAs) process. This switch offers high isolation, low insertion loss, and on-chip termination of the isolated ports. The HMC641ALP4E includes an on-chip, binary 2 to 4 line decoder that provides logic control from two logic input lines. The HMC641ALP4E comes in a 4 mm x 4 mm, 24-lead LFCSP package and operates from 0.1 GHz to 20 GHz. The switch operates with a negative supply voltage range of -5 V to -3 V and requires two negative logic control voltages. Rev.

Depending on the logic level applied to the CTRLA pin and the CTRLB pin, one RF path is in the insertion loss state while the other three paths are in an isolation state (see Table 4). The insertion loss path conducts the RF signal between the RF throw pin and RF common pin while the isolation paths provide high loss between RF throw pins terminated to internal 50 resistors and the insertion loss path. The ideal power-up sequence is as follows: 1. 2. 3. 4. Ground to the die bottom. Power up VSS. Power up the digital control inputs. The relative order of the logic control inputs is not important. However, powering the digital control inputs before the VSS supply can inadvertently become forward-biased and damage the internal ESD protection structures. Apply an RF input signal. The design is bidirectional; the RF input signal can be applied to the RFC pin while the RF throw pins are the outputs, or the RF input signal can be applied to the RF throw pins while the RFC pin is the output. All of the RF pins are dc-coupled to 0 V, and no dc blocking is required at the RF pins when the RF line potential is equal to 0 V. The power-down sequence is the reverse of the power-up sequence.

Power supply port is connected to the VSS test point, J8, and control voltages, CTRLA and CTRLB, are connected to the A and B test points, J6 and J7, and the ground reference is connected to the GND test point, J9. On the supply trace, VSS, use a 1000 pF bypass capacitor to filter high frequency noise. EVALUATION BOARD The EV1HMC641ALP4 is a 4-layer evaluation board. Each copper layer is 0.5 oz (0.7 mil) and separated by dielectric materials. Figure 14 shows the stack up for this evaluation board. W = 16mil 0.5oz Cu (0.7mil) TOTAL THICKNESS ~62mil RO4350 0.5oz Cu (0.7mil) The RF input and output ports (RFC, RF1, RF2, RF3, and RF4) are connected through 50 transmission lines to the SMA launchers, J1 to J5. These SMA launchers are soldered onto the board. A through calibration line connects the unpopulated J10 and J11 launchers; this transmission line estimates the loss of the PCB over the environmental conditions being evaluated, as shown in Figure 16. T = 0.7mil H = 10mil 0.5oz Cu (0.7mil) FR4-08 Table 5 shows the evaluation board components. 0.5oz Cu (0.7mil) RO4350 0.5oz Cu (0.7mil) 16094-013 0.5oz Cu (0.7mil) G = 13mil Figure 14. The EV1HMC641ALP4 Evaluation Board (Cross Sectional View) All RF and dc traces are routed on the top copper layer whereas the inner and bottom layers are grounded planes that provide a solid ground for the RF transmission lines. Top dielectric material is a 10 mil Rogers RO4350. The middle and bottom dielectric materials provide mechanical strength. The overall board thickness is approximately 62 mil, allowing the subminiature version A (SMA) launchers to be connected at the board edges. Table 5. Evaluation Board Components Component J1 to J5 J6 to J9 J10, J11 C1 U1 PCB The RF transmission lines were designed using a coplanar waveguide (CPWG) model, with trace width of 16 mil and ground clearance of 13 mil for a characteristic impedance of 50 . For optimal RF and thermal grounding, arrange as many plated through vias as possible around transmission lines and under the exposed pad of the package. Rev.
