Patent ID: 8175185

Claim:
A radio frequency (RF) integrated circuit comprising: an RF receiver that generates inbound data based on an inbound RF signal; a RF transmitter that includes: a transmitter processing module that generates a processed signal and a modulating signal based on outbound data, wherein the processed signal includes one of: a baseband signal and a low intermediate frequency signal; an up-conversion module, coupled to the transmitter processing module, that up-converts the processed signal to generate an up-converted signal; a first programmable filter module, coupled to the up-conversion module, that generates a first plurality of delayed signals from the up-converted signal and that generates a filtered up-converted signal by combining the up-converted signal and the first plurality of delayed signals, wherein a delayed signal of the first plurality of delayed signals is scaled based on one of a first plurality of coefficients, wherein the first plurality of coefficients are selected based on a control signal; a radio transmitter front-end, coupled to the first programmable filter module, that includes a polar amplifier that amplifies and amplitude modulates the filtered up-converted signal based on the modulating signal to generate a transmit signal; and a processing module, coupled to the first programmable filter module, that generates the control signal to attenuate at least one RF spur of the up-converted signal.
