摘要

开发了一个由5个PHEMT 0.4-0.5 W驱动芯片和4个1-1.5 W功率放大器芯片组成的28-40 GHz系列。强大的0.25 /spl mu/m t栅技术使组成的500 /spl mu/m PHEMT电池始终保持>70%的产量和>35%的功率增加效率。这些mmic的高产量和低成本使其成为当今毫米波通信系统的重要组成部分。

MMIC amplifier chip sets for Ka-band communications applications

A family of five PHEMT 0.4-0.5 W driver chips and four 1-1.5 W power amplifier chips spanning 28-40 GHz has been developed. A robust 0.25 /spl mu/m T-gate technology enables the constituent 500 /spl mu/m PHEMT cells to consistently achieve yields >70% and power added efficiency >35%. The demonstrated high yield and resulting low cost of these MMICs makes them attractive building blocks for today's millimeter-wave communications systems.
