[3] Choose values of R1 & R2 between 4.3 and 20 Ohms for
best noise performance
The circuit board used in the nal 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 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.
