108646 Eval Board
[1] Reference this number when ordering complete 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 ground 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.
