Abstract

See full text

A super-heterodyne receiver includes 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. The receiver further includes 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. The first filter set comprises a first plurality of input filters having respective center frequencies ranging from approximately 1250 MHz to 6250 MHz, a second plurality of input filters having respective center frequencies ranging from approximately 8250 MHz to 18500 MHz, and a third plurality of center frequencies ranging from approximately 24000 MHz to 38000 MHz. The first filter has a center frequency of approximately 8000 MHz, the second filter has a center frequency of approximately 3500 MHz, and the first oscillator is adjustable between approximately 8250 MHz and 23000 MHz.
