Item Description
package ground leads and exposed pad must be connected J1 to J2 PCB mount Subminiature Version A (SMA) connector directly to the ground plane similar to that shown in Figure 19. J5, J6 DC pin A sufficient number of via holes must be used to connect the top C1, C2 0.01 μF capacitor, 0502 package and bottom ground planes. The EV1HMC788ALP2 evaluation C3 100 pF capacitor, 0402 package board must be mounted to an appropriate heat sink. C4 2.2 μF Case A package R1 0 Ω resistor, 0402 package Figure 18 shows the schematic of the EV1HMC788ALP2 L1 Inductor, conical 6.35 μH evaluation board. The board is powered by a single supply between U1 HMC788ALP2E 4.5 V and 5.5 V and is decoupled by a 2.2 µF capacitor and a 100 pF PCB2 129549 evaluation PCB capacitor. DC blocking capacitors are instal ed at the RFIN and 1 Reference this number when ordering the complete evaluation PCB. RFOUT ports.
