Abstract :
This paper presents two new diode configurations for use with six-port based demodulators. The first proposed diode configuration allows a simplified diode to filter/amplifier interface. The second configuration allows for full-wave rectification and suppression of odd-order harmonics. A demodulator prototype utilizing the new diode concept is designed for a center frequency of 7.5 GHz and with a bandwidth of 1 GHz for verification. The demodulator includes the six-port correlator, diodes and amplifiers needed to recover the baseband data.
