Active channelized integrated antenna system
First Claim
1. An active channelized antenna system comprising:
- an antenna array operable over a multi-octave frequency band of an input signal spectrum to provide one or more antenna output signals;
an electronics module comprising;
a plurality of baluns coupled to the one or more antenna output signals, respectively,a plurality of limiters each coupled to an output of a respective balun,a plurality of random noise generators,a plurality of multiplexers each coupled to an output of a respective limiter and a respective random noise generator and configured to divide an input signal spectrum in said multi-octave frequency band into a plurality of channelized frequency band components each of less than an octave bandwidth, anda plurality of amplifiers each of less than an octave bandwidth to provide an amplified component signal for a respective frequency band;
combiner circuitry for combining the amplified frequency band components into a composite signal which replicates the input signal spectrum; and
a transmission medium for transmitting the composite signal to a remotely located receiver system.

Abstract
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.
