Description
PCB Mount SMA Connector
2 mm DC Header
12 pF Capacitor, 0402 Pkg.
6.8 pF Capacitor, 0402 Pkg.
5.6 pF Capacitor, 0402 Pkg.
39 pF Capacitor, 0402 Pkg.
100 pF Capacitor, 0402 Pkg.
2.2 μF Capacitor, Tantalum
47 nH Inductor, 0603 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 con-
nected 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.
