Claim Text:
1. A super-heterodyne receiver comprising: a plurality of input filters configured to receive an input signal and divide up a tuning range of the input signal into a plurality of respective bands, wherein the input filters are divided into a plurality of filter sets, each having a respective filter set output, and each of the input filters has a center frequency and a bandwidth; a first amplifier having an input coupled to a first filter set output and an output coupled to a first mixer; a second amplifier having an input coupled to a second filter set output and an output coupled to a second mixer; a first local oscillator coupled to an input of the first mixer and an input of the second mixer, the local oscillator configured to produce a first oscillator signal; a third mixer having a first input coupled to a third filter set output and a second input coupled to a second local oscillator configured to produce a second oscillator signal; a first filter having an input coupled to an output of the first mixer, the first filter having a center frequency and a bandwidth; a second filter having an input coupled to an output of the second mixer, the second filter having a center frequency and a bandwidth; a third filter having an input coupled to the output of the third mixer, the third filter having a center frequency and a bandwidth, wherein an output of the third mixer is coupled to the input of the second amplifier; a fourth mixer coupled to a third local oscillator and configured to receive the outputs of both the first and second filters, the third local oscillator configured to produce a third oscillator signal; a fourth filter having an input coupled to the fourth mixer, the fourth filter having a center frequency and a bandwidth; and a digital sampling detector having an input coupled to an output of the fourth filter and configured to produce a receiver output.
