Signal J1 - J2 PCB Mount SMA Connector lines should have 50 Ohm impedance while the J3 - J4 DC Pin package ground leads and package bottom should C1, C2 Capacitor, 0402 Pkg. be connected directly to the ground plane similar to C3 100 pF Capacitor, 0402 Pkg. that shown. A sufficient number of via holes should C4 1000 pF Capacitor, 0603 Pkg. be used to connect the top and bottom ground C5 2.2 µF Capacitor, Tantalum planes. The evaluation board should be mounted to R1 Resistor, 0805 Pkg. an appropriate heat sink. The evaluation circuit board L1 Inductor, 0603 Pkg. shown is available from Analog Devices upon request.
