Signal J1 - J2 PC Mount SMA Connector lines should have 50 Ohm impedance while the J3 2 mm DC Header package ground leads and exposed paddle should C1, C2 Capacitor, 0402 Pkg. be connected directly to the ground plane similar to C3 10,000 pF Capacitor, 0805 Pkg. that shown. A sufficient number of via holes should R1 22 Ohm Resistor, 0805 Pkg. be used to connect the top and bottom ground L1 Inductor, 0805 Pkg. planes. The evaluation board should be mounted U1 HMC311LP3 / HMC311LP3E to an appropriate heat sink. The evaluation circuit PCB [2] 106493 Evaluation PCB board shown is available from Hittite upon request.
