Coax Fixed Diplexer

Back to Fixed Diplexer

coax fixed diplexer 2 CMC Coax 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.

CMC Part Number 307500 shown at right with the following specifications:

Chan 1:  1022 - 1038 MHz
Chan 2:  1082 - 1098 MHz
Insertion Loss:  1.2 dB, MAX
Isolation between Channels:  60 dB, MIN

coax fixed diplexerCoax Fixed Diplexers are offered in circulator designs, for enhanced isolation, and non-circulator designs for non-directional applications and to minimize loss. Coax resonator designs offer high isolation, compact size, and economy.

Please refer to the DIPLEXER WORKSHEET and contact our engineering staff for assistance in specifying a diplexer to meet your exact requirements.

CMC Part Number 602375 shown at left.

CMC P/N 617375 (pictured above) is developed for high reliability UAV applications in Ku band. This family of diplexers combines light weight rugged construction, very low insertion loss and over 90 dB of isolation between channels. Integral harmonic supression filters and power monitoring couplers are included. Interface connections to coax and/or waveguide are available.
