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. refer to “Components for
selected frequencies” table for part number.
