Description
PCB Mount SMA Connector
12 Pin DC Connector
1000 pF Capacitor, 0402 Pkg.
100 pF Capacitor, 0402 Pkg.
10k pF Capacitor, 0402 Pkg.
4.7 µF Tantalum Capacitor, Case A Size
680 nH Inductor, 0805 Pkg.
330 nH Inductor, 0603 Pkg.
The circuit board used in the application should use
RF circuit design techniques. Signal lines should
have 50 Ohm impedance while the package ground
leads and exposed paddle should be connected
directly to the ground plane similar to that shown.
A sufficient number of via holes should be used to
connect the top and bottom ground planes. The
evaluation circuit board shown is available from Hit-
tite upon request.
