Abstract
Official abstract text for this publication.
A radio transmitter front end for use in a radio frequency (RF) transceiver includes at least one amplifier stage operable to generate a transmit signal in response to an upconverted signal. A feedback generator is operable to generate a transmit feedback signal in response to the transmit signal. A control signal generator is operable to generate at least one filter control signal in response to the transmit feedback signal. A notch filter is operable to filter out of band noise while passing in-band frequencies to the at least one amplifier stage, under control of the at least one filter control signal.
First claim
Opening claim text (preview).
What is claimed is: 1. A radio transmitter front end for use in a radio frequency (RF) transceiver, the radio transmitter front end comprising: at least one amplifier stage operable to generate a transmit signal in response to an upconverted signal; a feedback generator, coupled to the at least one amplifier stage, operable to generate a transmit feedback signal in response to the transmit signal, by determining an out of band signal rejection of the transmit signal; a control…
