GaAs MMIC 4x2 SWITCH
MATRIX, 0.7 - 3.0 GHz
Evaluation PCB

The circuit board used in the final application should be generated with proper RF circuit design techniques.
Signal lines at the RF port should have 50 ohm impedance and the package ground leads should be connected
directly to the ground plane similar to that shown above. A generous number of ground vias should be used
to interconnect top/bottom ground planes. The evaluation circuit board shown above is available from Hittite
Microwave Corporation upon request.
