ABSTRACT:
A novel nonfrequency-converting microwave radio repeater for use in multichannel telecommunications is disclosed. A single microwave amplifier provides the requisite gain for two different angle-modulated radio frequency signals. Bandpass filters and circulators permit duplex operation by channeling the received signals through the repeater. The two radio frequency signals are amplified simultaneously in the same amplifier and then separated to be retransmitted at the same frequency in the proper path direction.
