Abstract
An integrated multi-mode bandpass sigma-delta radio frequency receiver subsystem with interference mitigation includes a first intermediate frequency amplifier. At least one mixer for mixing the output of the first amplifier and an oscillator signal. A second IF amplifier for amplifying and filtering the output of the at least one mixer. A multi mode multi bandwidth sigma delta analog digital converter for providing digital output signals with high dynamic range. A digital mixer providing I and Q signals a decimation network providing I and Q signals at reduced programmable data and clock frequencies and a formatting network for arranging the I and Q signals into a predetermined format for use with a digital signal processor.
