Dual RF transceiver system with interference cancellation and methods for use therewith
First Claim
1. A voice, data and RF integrated circuit (IC) comprising:
- a first radio frequency (RF) receiver section coupled to receive a first inbound RF signal over a first range of frequencies and generate a first amplified RF signal, wherein the first inbound RF signal includes a desired RF signal component and an undesired signal component;
a second RF receiver section coupled to receive a second inbound RF signal over a second range of frequencies that is different from the first range of frequencies and generate a second amplified RF signal, wherein the second inbound RF signal includes the undesired signal component; and
a first RF cancellation module, coupled to the first RF receiver section and the second RF receiver section, that provides a desired RF signal from the desired RF signal component while attenuating the undesired signal component.

Abstract
A voice, data and RF integrated circuit (IC) includes a first radio frequency (RF) receiver section coupled to receive a first inbound RF signal over a first range of frequencies and generate a first amplified RF signal, wherein the first inbound RF signal includes a desired RF signal and an undesired signal. A second RF receiver section is coupled to receive a second inbound RF signal over a second range of frequencies that is different from the first range of frequencies and generate a second amplified RF signal, wherein the second inbound RF signal includes the undesired signal. A first RF cancellation module provides the desired RF signal while attenuating the undesired signal.
