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

[3] Due to the very high frequency operation of this product
a custom LC4 PCB footprint and solder stencil are required
for this design. Performance shown in this data sheet
was produced using this custom footprint. DO NOT USE
Hittite’s standard LC4 footprint. Please contact Applications
for details.
