Abstract
A homodyne receiver is provided for receiving GSM and UMTS transmissions. The receiver may also be used for other transmission schemes. The receiver includes an electronically reconfigurable low pass filter and an off set generator for providing DC offset correction for offsets which may be generated as a result of coupling between a local radio frequency oscillator and the receiver front end.
