Description
SMA Connector
DC Pin
22 pF Capacitor, 0402 Pkg.
10 nF Capacitor, 0402 Pkg.
1 nF Capacitor, 0402 Pkg.
0.1 µF Capacitor, 0402 Pkg.
4.7 µF Case A, Tantulum
0 Ohm Resistor, 0402 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.
