117360 Evaluation PCB
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 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
board should be mounted to an appropriate heat
sink. The evaluation circuit board shown is available
from Hittite upon request.
