15-Gb/s 50-cm Wireless Link Using a High-Power Compact III–V 84-GHz Transmitter

This paper reports on a 15-Gb/s wireless link that employs a high-power resonant tunneling diode (RTD) oscillator as a transmitter (Tx). The fundamental carrier frequency is 84 GHz and the maximum output power is 2 mW without any power amplifier. The reported performance is over a 50-cm link, with simple amplitude shift keying modulation utilized. The 15-Gb/s data link shows correctable bit error rate (BER) of
$4.1 \times 10^{-3}$
, while the lower data rates of 10 and 5 Gb/s show a BER of
$3.6 \times 10^{-4}$
and
$1.0 \times 10^{-6}$
, respectively. These results demonstrate that the RTD Tx is a promising candidate for the next-generation low-cost, compact, ultrahigh data rates wireless communication systems.
