Abstract

A fully monolithic HBT power amplifier that has established new benchmarks for bandwidth and efficiency at X-band is reported. Power-added efficiencies of 56% max/38% min/44.4% average across 7 to 11 GHz are the highest X-band efficiencies and widest bandwidth reported for MMIC HPA's. These amplifiers have demonstrated high power levels (up to 7.3 watts) with high gain (11 to 14.1 dB) under thermally challenging long pulse (500 /spl mu/sec) high duty cycle (25%) conditions. The amplifiers were fabricated using an advanced re-aligned AlGaAs/GaAs power HBT process with a plated bathtub heat sink.<>

5瓦高效率宽带7至11 GHz HBT MMIC功率放大器

报道了一种全单片HBT功率放大器，为x波段的带宽和效率建立了新的基准。在7至11 GHz范围内，功率增加效率平均为56% max/38% min/44.4%，是MMIC HPA报告的最高x波段效率和最宽带宽。这些放大器在具有热挑战性的长脉冲(500 /spl mu/sec)高占空比(25%)条件下具有高功率电平(高达7.3瓦)和高增益(11至14.1 dB)。放大器采用先进的重新对准AlGaAs/GaAs功率HBT工艺和镀浴缸式散热器制造。
