Radio frequency integrated circuit having reduced receiver noise levels
First Claim
1. A radio frequency integrated circuit (RFIC) comprises:
- digital to analog converter (DAC) operably coupled to convert outbound symbols into outbound baseband signals, wherein the digital to analog converter is fabricated within a DAC portion of a substrate of the RFIC;
analog to digital converter (ADC) operably coupled to convert inbound baseband signals into inbound symbols, wherein the analog to digital converter is fabricated within an ADC portion of the substrate; and
radio module operably coupled to convert the outbound baseband signals into outbound radio frequency (RF) signals and to convert inbound RF signals into the inbound baseband signals, wherein the radio module is fabricated within a radio portion of the substrate, wherein the DAC portion of the substrate is physically between the ADC portion and the radio portion of the substrate to provide the radio module with noise immunity from the analog to digital converter.

Abstract
A radio frequency integrated circuit (RFIC) includes a digital to analog converter, an analog to digital converter, and a radio module. The digital to analog converter (DAC) is operably coupled to convert outbound symbols into outbound baseband signals, wherein the digital to analog converter is fabricated within a DAC portion of a substrate of the RFIC. The analog to digital converter (ADC) is operably coupled to convert inbound baseband signals into inbound symbols, wherein the analog to digital converter is fabricated within an ADC portion of the substrate. The radio module is operably coupled to convert the outbound baseband signals into outbound radio frequency (RF) signals and to convert inbound RF signals into the inbound baseband signals. The radio module is fabricated within a radio portion of the substrate, wherein the DAC portion of the substrate is physically between the ADC portion and the radio portion of the substrate.
