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.

I. Introduction

With the development of modern multimedia technology, there is a great demand for ultrahigh speed wireless communication. The typical application scenarios include wireless local area networks, wireless personal area networks, kiosk downloading, wireless connection in data centers, chip-to-chip interconnects, wireless backhauling, nano cells, and so on. Based on the extrapolation of Edholm’s law and future demand analysis, the data rate in the near future is expected to reach about 100 Gb/s [1]–[3].
