Abstract :
Targeting the differential RF/microwave circuit design methodology for improved broadband wireless data transmission, a novel differential 7.5 GHz six-port modulator and demodulator pair was designed and manufactured. Measurements show a good 256-QAM modulated signal at 50 Msymbol/s and an accurately 16-QAM demodulated signal at 200 Msymbol/s.
