[1] When requesting an evaluation board, please reference

the appropriate evaluation PCB number listed in the table

“Components for Selected Frequencies.”

[2] Please refer to ‘Components for Selected Frequencies’ table

for values.

[3] Circuit Board Material: Rogers 4350

The circuit board used in the final application should

be generated with proper RF circuit design tech-

niques. Signal lines at the RF port should have 50

ohm impedance and the package ground leads and

exposed paddle should be connected directly to the

ground plane similar to that shown above. The eval-

uation circuit board shown above is available from

Hittite Microwave Corporation upon request.
