具有高增益平面阵列的紧凑型无线终端（WT）是为无线IP接入系统（WIPAS）开发的，该系统是26 GHz频段的点对多点FWA（固定无线接入）系统。通过使用交替相位馈电单层波导阵列天线和MMIC（微波单片IC）技术，实现了成本的大幅降低和小型化。该终端的体积为 190/spl 次/190/spl 次/55 mm/sup 3/，重量小于 2.0 kg，可容纳超过 31 dBi 的超高效天线，带天线罩、RF 模块、IF 模块、用于调制解调器的 ASIC（专用 IC）、TDMA（时分多址）设备控制和 MAC（介质访问控制）。终端上仅连接一根具有 24 DC 电源的以太网电缆。本文描述了 WT 的设计，重点介绍了独特的天线和射频模块。
A compact wireless terminal (WT) with a high gain planar array has been developed for the Wireless IP Access System (WIPAS), which is a point-to-multipoint FWA (fixed wireless access) system in 26 GHz frequency band. Drastic cost reduction and downsizing are realized by using an alternating phase fed single layer waveguide array antenna and MMIC (microwave monolithic IC) technologies. This terminal is 190/spl times/190/spl times/55 mm/sup 3/ in volume and less than 2.0 kg in weight which accommodates over 31 dBi very high efficiency antenna with radome, RF module, IF modules, ASIC (application specific IC) for modem, TDMA (time division multiple access) equipment control, and MAC (medium. access control). Only an Ethernet cable with 24 DC power supply is attached on the terminal. This paper describes the design of WT with the focus upon the unique antenna and RF module.
