	<span lang=\"EN-US\">We present in this paper a wideband <i>RF</i> demodulator using a five-port correlator
and a power detector for channel sounding applications. The demodulator has been
fabricated using microstrip components. The correlator receives from the five-port
qualities that allow it to be low-cost and less sensitive to the phase and amplitude
imbalances. A calibration procedure is proposed to find the complex envelope of
the <i>RF</i> signal applied at the input of
the five-port correlator. Simulation with Advanced Design System software and measurement
results have been conducted to demonstrate its capabilities as a <i>RF</i> signal demodulator operating in a wideband
around 2.4 GHz frequency.</span><span lang=\"EN-US\"><o:p></o:p></span>
