A system and method for providing a field configurable radio frequency
communication system including an intermediate frequency digital signal
processing circuit therefor. The intermediate frequency digital signal
processing circuits includes digital transmitter and receiver circuit
paths, a digital baseband circuit, control registers and an interface
circuit. The transmitter and receiver circuit paths and the baseband
circuits include digital processing circuits that are configurable by
commands provided to the control register via the interface circuit to
select the transmitter or receiver mode of operation, to select the
signaling scheme of waveform employed, to configure the signal processing
functions of the transmitter or receiver circuit paths, and to select the
use of any of a plurality a baseband signal processing functions.
