Abstract
A comb limiter combiner for front end filtering reduces bit error rates with an increased reception range. Notch filters are tuned to suppress interfering frequency-hopped signals. An output comb filter suppresses out-of-band intermodulation products generated by any non-linear devices (such as limiters and the notch filters) in each of the comb limiter combiner sub-bands. Sensitivity is further increased by the use of cryogenically cooled high temperature superconductor components for the filters, amplifiers, and limiters used in each sub-band.
