Evaluation Circuit Board
The circuit board used in the final application should
use RF circuit design techniques. Signal lines
should have 50 ohm impedance while the pack-
age ground leads 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 cir-
cuit board as shown is available from Hittite Micro-
wave Corporation upon request.

* R2 = R3 = 100 Ohm.
These resistors are optional
and may be used to enhance
decoupling of the RF path
from the control inputs.
