<p>An active channelized antenna system includes an antenna array operable over a multi-octave frequency band to provide one or more antenna output signals. An electronics module includes multiplexer circuitry responsive to the one or more antenna output signals configured to divide an input signal spectrum into a plurality of frequency band components each of less than an octave bandwidth. The electronics module includes a plurality of amplifiers each of less than an octave bandwidth to provide an amplified component signal for a respective frequency band. Combiner circuitry included with the electronics module is configured to combine the amplified frequency band components into a composite signal. A transmission medium such as a coaxial cable, fiber optic line or free space, is configured to transmit the composite signal to a remotely located receiver system. The antenna system may be employed as a repeater system</p> |
