Abstract
A duplex RF repeater for use in a personal communications system distributes and enhances time division duplexed signals at a single RF carrier. The duplex RF repeater includes an up-link amplifier and a down-link amplifier which amplify the time division duplexed signals at the single RF carrier. The repeater also includes a down-stream antenna, which links the repeater with a subscriber, and a controller which decreases the gain of one of the up-link or the down-link amplifiers when an RF signal is present at the other of the up-link or the down-link amplifiers to prevent self-oscillation caused by over coupling between the two amplifiers.
