Description
PCB Mount SMA Connector
1 Pin DC Connector
14 Pin DC Connector
100 pF Capacitor, 0402 Pkg.
1000 pF Capacitor, 0402 Pkg.
2.2 μF Capacitor, CASEA Pkg.
1.8 Ohm Resistor, 1206 Pkg.
24 nH Inductor, 0603 Pkg.
The circuit board used in the final 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 circuit board shown is available from
Hittite upon request.
