Abstract:
Multi-function receivers are disclosed in which high dynamic range active microwave filters using nanoscale devices are disposed within a switched channelizer stage. In an embodiment the receiver includes an input low noise amplifier, a switched channelizer comprised of active filters utilizing nanoscale devices, an output amplifier, a mixer, and an analog to digital converter. Additionally, the use of highly selective active filters in the channelizer allows for the optional elimination of the mixing stage, improving cost and overall volume.
