In addition, almost any value of rejection bandwidth can be provided by the proper selection of the number of sections and coupling iris dimensions. Passband insertion loss also minimizes with the 8” high-Q aluminum cavities.

A 7/8” unflanged connection is standard. Flanged is also provided on request.  This design supports power levels up to 3 KW
