APPLICATIONS INFORMATION

EVALUATION BOARD

The HMC974LC3C evaluation printed circuit board (PCB)

must use RF circuit design techniques. Signal lines must have

50 Ω impedance while the package ground leads must connect

directly to the ground plane of the PCB. The exposed metal

ground planes connect together with via holes. The evaluation

PCB shown in Figure 13 is available from Analog Devices, Inc.,

upon request.

Figure 14 shows the EVAL-HMC974LC3C schematic. Figure 15

shows the typical application circuit.
