Abstract:
1. A radio frequency integrated circuit (RFIC) comprises: a low noise amplifier coupled to amplify an inbound radio frequency (RF) signal to produce an amplified inbound RF signal, wherein the low noise amplifier is fabricated within a radio portion of a substrate of the RFIC; a 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 the substrate of the RFIC; and an analog to digital converter (ADC) operably coupled to convert inbound baseband signals into inbound symbols, wherein the ADC is fabricated within a ADC 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 isolation when the low noise amplifier and the ADC are active and the DAC is inactive.
