Patent ID: 7436910

Claim:
Receive path circuitry for a bandpass sampling receiver having decoupled quantization, comprising: bandpass filter circuitry having a center frequency within a frequency range of interest and having a bandwidth less than the frequency range of interest; non-quantizing sampling circuitry configured to receive a filtered signal from the bandpass filter circuitry and to receive a bandpass sampling clock signal as an input, the bandpass sampling clock signal meeting Nyquist sampling criteria of the bandpass filter but not meeting Nyquist sampling criteria of the total frequency range of interest; an analog interpolation filter coupled to receive the output of the non-quantizing sampling circuitry, the analog interpolation filter having a center frequency within a Nyquist zone of operation for the non-quantizing sampling circuitry; and analog to digital converter (ADC) circuitry configured to receive a quantization sampling clock signal and to quantize an analog signal received from the analog interpolation filter.
