Band Reject Filter – Waveguide
Ka Band Reject Filter
This filter was initially designed to isolate the fundamental transmitter out put signal from the local oscillator in high reliability Ka-BAND communications equipment. Constructed in WR42, similar to above photo, the filter exhibits low passband insertion loss and high isolation in the reject band.
