Description
PCB Mount SMA Connector
2 mm DC Header
10 pF Capacitor, 0402 Pkg.
100 pF Capacitor, 0402 Pkg.
100 pF Capacitor, 0402 Pkg.
1000 pF Capacitor, 0402 Pkg.
2.2 μF Capacitor, Tantalum
100 pF Capacitor, 0402 Pkg.
1.2 pF Capacitor, 0402 Pkg.
The circuit board used in this 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 board should be mounted to an
appropriate heat sink. The evaluation circuit board
shown is available from Hittite upon request.
