Tunable Diplexers

CMC Tunable Diplexers consist of two tunable Bandpass Filters sharing a common port. Signals applied to the common port are separated in accordance with the passband frequency of each filter network. tunable diplexer 2 Signals applied to either channel are isolated from the adjacent channel, but are combined at the common port.

Tunable Diplexers are offered in circulator designs, to enhance isolation, and non-circulator designs for non-directional applications and to minimize loss. Channel separation may be fixed offset or independent. In addition to the normal manual tuning and calibration options, stepper motor control is offered for automated applications.

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