114398 Evaluation PCB
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.
