主 题:wireless link 16 quadrature amplitude modulation(16-QAM) super-heterodyne transceiver modules sub-harmonic mixer(SHM)
摘 要:This paper presents a 220-GHz-band 7-m wireless link with a 45-Gbps transmission data rate by using 16 quadrature amplitude modulation(16-QAM).Super-heterodyne transceiver modules are developed for transmission and reception of the modulated signals,which consist of a Schottky barrier diodes(SBD)based sub-harmonic mixer(SHM),an InP HEMT low noise amplifier(LNA),a waveguide band-pass filter(BPF),and a 108-GHz local oscillator(LO)multiplier *** transmitter features a peak transmit power of 1.41 dBm,and the IF frequency varies from 5 GHz to 20 ***,the receiver features a conversion gain of 9.3 dB in average and a noise temperature of 3052.8 *** measured results indicate that the transceiver modules enable data transmission of a 45-Gbps 16-QAM signal with Signal-Noise-Ratio(SNR)from 11.59 dB to 15.36 dB in a 7-m line-of-sight channel.
