105697 Eval Board

[1] Reference this number when ordering complete evaluation PCB

[2] Circuit Board Material: Rogers 4350

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 backside ground slug 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 circuit board shown is available

from Hittite upon request. This evaluation board is

designed for single ended input testing. J2 and J3

provide differential output signals.
