Description
PCB Mount SMA RF Connector
DC Pin
100 pF Chip Capacitor, 0402 Pkg.
1000 pF Chip Capacitor, 0603 Pkg.
2.2 μF Capacitor, Tantalum
0.01 μF Chip Capacitor, 0402 Pkg.
51 nH Chip Inductor, 0402 Pkg.
18 nH Chip Inductor, 0402 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.
