摘要

Microwave performance results are presented of the first monolithically integrated GaAs-AlGaAs complementary HBT push-pull amplifier fabricated using selective molecular beam epitaxy and a merged HBT process. The push-pull amplifier integrates four n-p-n transistors with one p-n-p transistor on the same GaAs chip. The amplifier has a sharp DC characteristic curve with no crossover offset, a voltage swing of 6.3 V using a 9-V supply, and a linear voltage gain of 20. The bandwidth is DC to 2.5 GHz, with a saturated output power of 7.4 dBm at 2.5 GHz.
