[1] When requesting an evaluation board, please reference the
appropriate PCB number listed in the table “Components for
Selected Frequencies.”
[2] Circuit Board Material: Arlon 25FR / FR4
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 con-
nect the top and bottom ground planes. The evalua-
tion circuit board shown is available from Hittite upon
request.
