RF Match Data shown in the performance graphs was taken
in the test circuit shown at right. Layout is important for proper 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 recommends the use of a high impedance printed inductor
Lambda/4 in length. Please contact the factory for an evaluation board and/or more detailed application support.
