Tunable Multicouplers

The TMC-100/160 are Tunable Multicouplers enabling up to four transceivers to operate simultaneously in transmission and reception mode using a common antenna. The four digitally controlled bandpass filters within the multicouplers cover the VHF or UHF communication band. Each filter is a three pole design to provide high selectivity with a nominal 3 dB bandwidth of 0.7 (VHF), 0.3 (UHF), 1.0 or 2.0%. Each filter is controlled remotely through an independent digital interface. When a frequency command is received control circuitry drives a stepper motor to properly position the filter shaft. The multicouplers may be optimized for custom interface, mechanical and performance requirements.
