Abstract

The invention relates to a Ultra Wide Band signal demodulator comprising a phase shifter (Phase) circuit for phase shifting an input signal (Vin) and for delivering a phase shifted signal to an amplifying circuit (Gain) for amplifying the phase shifted signal and for generating an amplified signal (VDO). The demodulator further comprises a multiplier (Multiplier) for mixing the input signal with the amplified signal.
