A high-gain cell enhancer

A cell enhancer that offers a combination of high-grain and high output power with extremely good linearity is described. The prototype repeater offers an active gain of at least 100 dB over a bandwidth of several megahertz. A linearized broadband amplifier is combined with a novel system for reducing the effect of the damaging mutual coupling between the transmitter and receiver, resulting in a transparent repeater that offers uses greater flexibility and functionality than current designs.<
