Abstract

Radio-frequency (RF) apparatus includes receiver analog circuitry that receives an RF signal and provides at least one digital signal to receiver digital circuitry that functions in cooperation with the receiver analog circuitry. The receiver analog circuitry and the receiver digital circuitry are partitioned so that interference effects between the receiver analog circuitry and the receiver digital circuitry tend to be reduced.

First claim

The invention claimed is:

1. An apparatus comprising:
a radio-frequency (RF) receiver, comprising:
first down-converter circuitry coupled to receive an RF signal and to generate first in-phase and first quadrature signals;
analog-to-digital converter (ADC) circuitry coupled to receive the first in-phase and first quadrature signals and to generate second in-phase and second quadrature signals;
second down-converter circuitry coupled to receive the second in-phase and second q…
