FRACTIONAL-N SYNTHESIZER w/ INTEGRATED VCO
795 - 945, 1590 - 1890, 3180 - 3780 MHz
Evaluation PCB, 2xfo Mode
7
The circuit board used in the 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 circuit board shown is available from Hittite upon request.
