Bill of Materials The HMC974LC3C evaluation printed circuit board (PCB) Reference DesignatorDescription must use RF circuit design techniques. Signal lines must have J1 Eight-position vertical header 50 Ω impedance while the package ground leads must connect J2 to J7 K connector, SRI directly to the ground plane of the PCB. The exposed metal J8 Terminal strip, single row, 3-pin package base must connect to VEE. Ensure the top and bottom JP1, JP2 Two position vertical header ground planes connect together with via holes. The evaluation C1 to C3, C5, C6, C8 to C10, 100 pF capacitor, 0402 PCB shown in Figure 13 is available from Analog Devices, Inc., C15 upon request. C4, C7, C11 330 pF capacitor, 0402 C12 to C14 4.7 μF tantalum capacitor Figure 14 shows the EVAL-HMC974LC3C schematic. Figure 15 TP1 to TP4 DC pin shows the typical application circuit.
