Product Specifications - July 1997

(2 of 4)

RF Match Data shown in the performance graphs was taken

in the test circuits shown at right and on page 3. Layout is

important for proper operation. Phase length of input and out-

put 50

Ω line varies as a function of exact desired frequency

of operation. Output shunt inductor effects output perfor-

mance. Celeritek recommends the use of a high impedance

printed inductor Lambda/4 in length. Please contact the facto-

ry for an evaluation board and/or more detailed application

support.
