RF Match Data shown in the performance graphs was taken

in the test circuit shown at right. Layout is important for prop-

er operation. Phase length of input and output 50

Ω line varies

as a function of exact desired frequency of operation. Output

shunt inductor effects output performance. Celeritek recom-

mends the use of a high impedance printed inductor

Lambda/4 in length. Please contact the factory for an evalua-

tion board and/or more detailed application support.
