• Because 60 GHz frequency band has been allotted for the research and development purpose of millimeter wave systems in Japan, various circuit components and systems have been fabricated by using printed transmission lines. The NRD guide (nonradiative dielectric waveguide) is another candidate as a transmission medium for millimeter wave integrated circuit applications since its performance has been shown to be excellent in this frequency band. This paper is concerned with the development of a 60 GHz digital transceiver for millimeter wave LAN use based on NRD guide technologies. The transceiver consists of frequency stabilized Gunn oscillator, circulator,PIN diode modulator, balanced mixer, directional coupler and transmitting and receiving pyramidal horn antennas. The notable advantages of the circuit components are the high reliability of the Gunn oscillator, the wide bandwidth of the circulator, and the high frequency operation of the PIN diode modulator beyond l00 Mbps. interference between transmitted and received signals, which must be caused by coupling between transmitting and receiving antennas, is eliminated by simple techniques such as introducing filters in the base band and IF circuits. By using NRD guide djgjtal transceivers, both-way data transmission between two computers can be achieved simultaneously and a 60 GHz wireless LAN system has been developed successfully.
