Ultra-compact high speed mmW transceiver using GaN Power Amplifier technology

Recent advances in high power millimeter wave (mmW) Gallium Nitride (GaN) technology combined with advances in high-speed modem modulation efficiency has enabled the development of an ultra-compact long range mmW transceiver. This paper outlines the various aspects of this transceiver front-end development including the compact mmW antenna, integrated mmW circuitry, and single-chip GaN Power Amplifier (PA). Data links configured using this transceiver were evaluated in-chamber and outdoors between two mountain tops. Data rates up to 6.5 Giga-bits-per-second (Gbps) were demonstrated.
