Programmable radio transceiver

An integrated evaluation and test module for a radio transceiver implemented on a semiconductor substrate, the radio transceiver comprising a receiver chain that generates a radio frequency signal, the integrated evaluation and test module being integrated on the semiconductor substrate with the radio transceiver and the integrated evaluation and test module comprising:

• a control input adapted to receive a digital control signal;
• a signal input adapted to receive a digitized version of the radio frequency signal from the receiver chain of the radio transceiver;
• a processing module coupled to the signal input and adapted to receive and process the digitized version of the radio frequency signal from the receiver chain of the radio transceiver, and to provide a digital output signal;
• a reference generator adapted to generate a digital reference signal based on information contained in the digital control signal;
• a comparator coupled to the reference generator and to the processing module and adapted to receive the digital output signal and the digital reference signal, the comparator being configured to compare the digital output signal with the digital reference signal and to generate an error signal that identifies discrepancies between the digital output signal and the digital reference signal;
• and
• an adjustment module coupled to the comparator and adapted to receive the error signal from the comparator and to generate digital adjustment data based at least in part on the error signal, the adjustment module being further adapted to provide the digital adjustment data to at least one component of the receiver chain of the radio transceiver to adjust at least one parameter of the at least one component so as to modify the radio frequency signal to reduce the error signal.
