ABSTRACT:
Receiver section (200) includes a compensation network (202) which compensates for undesired effects caused by synthesized LO (204). Compensation network (202) substantially duplicates the amplitude and phase delay of synthesized LO (204) allowing for a substantially flat demodulated frequency response to be achieved at output (122) which is independent of the bandwidth of synthesized LO (204).
