Evaluation Circuit Board
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 should be connected directly to the ground plane similar to that shown.
A sufcient number of VIA holes should be used to connect the top and bottom ground planes. The evaluation circuit
board as shown is available from Hittite Microwave Corporation upon request.
Evaluation Circuit Board Layout Design Details
* R2 = R3 = 100 Ohm.
These resistors are optional
and may be used to enhance
decoupling of the RF path
from the control inputs.
