Band Reject Filter - Waveguide

Reject Frequency 19.54 GHz ± 10 MHz
Reject Level 70 dB Min
Passband 19.73 - 21.1 GHz

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.

Individual Tuned Bandpass Filters

MODEL NO. ICB45
3 dB BW NOM'L MHz 10.0
40 dB BW NOM'L MHz 100
W DIM +/-.06 IN 3.00

The IC Series Filters yield a butterworth (maximally flat) response and are available with 2 thru 6 cavities. Tuning is accomplished by means of individual screwdriver shafts. All conducting surfaces are silver plated to minimize insertion loss in the passband. Filters in this series are available from 395-8400 MHz. Outline drawings available upon request.

Waveguide Fixed Diplexer

Frequency ranges 1 to 40 GHz

CMC Waveguide Fixed Diplexers consist of two Fixed Tuned Bandpass Filters sharing a common port. Signals applied to the common port are separated in accordance with the passband frequency of each filter network. Signals applied to either channel are isolated from the adjacent channel, but are combined at the common port. Waveguide Fixed Diplexers are offered in circulator designs, for enhanced isolation, and non-circulator designs for non-directional applications and to minimize loss. Waveguide resonator designs offer high isolation, high power handling, and extremely low loss.
