RF polar transmitter and integrated circuit with programmable filter module and methods for use therewith |
摘要 |
A radio frequency (RF) transmitter includes a transmitter processing module that generates a processed signal and a modulating signal based on outbound data. An up-conversion module up-converts the processed signal to generate an up-converted signal. A programmable filter module 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 polar amplifier amplifies and amplitude modulates the filtered up-converted signal based on the modulating signal to generate a transmit signal. A processing module generates the control signal to attenuate at least one RF spur of the up-converted signal. |
