Evaluation PCB
The circuit board used in the final 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 below. A
sufficient 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.

* R2 - R6 = 100 Ohm.
These resistors are optional
and may be used to enhance
decoupling of the RF path
from the control inputs.
