15 Gbps Wireless Link Using W-band Resonant Tunnelling Diode Transmitter

Abstract

A 15 Gbps wireless link over 50 cm distance is reported in this paper. A high power and low phase noise resonant tunneling diode (RTD) oscillator is employed as the transmitter. The fundamental carrier frequency is 84 GHz and the maximum output power is 2 mW without any power amplifier. The measured phase noise value was -79 dBc/Hz at 100 KHz and -96 dBc/Hz at 1 MHz offset. The modulation scheme used was amplitude shift keying (ASK). The 15 Gbps data link showed a correctable bit error rate (BER) of 4.1×10 -3 , while lower data rates of 10 Gbps and 5 Gbps had BER of 3.6×10 -4 and 1.0×10 -6 , respectively.Keywords -resonant tunneling diode, wireless communication, amplitude shift keying (ASK).
