摘要： An agile transceiver including a receiver channel that includes an input, a coarse tracking filter coupled to the input, the coarse tracking filter having a set of at least two bandpass filters for filtering signals from the input into at least two coarse pass bands, a mixer coupled to an output of the coarse tracking filter, a selected local oscillator coupled to the mixer for mixing with the output of the coarse tracking filter and shifting a desired coarse pass band to near a base band, a fine tracking filter for filtering the shifted and desired coarse pass band to a fine pass band, and a band pass ΣΔ demodulator for converting signals in the fine pass band from analog into digital. The agile transceiver may include a corresponding transmitter channel.
