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 50Ω 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
