Abstract
Baseband amplifiers have been fabricated in the transferred-substrate HBT process. A Darlington amplifier achieved a DC gain of 15.6 dB with >50 GHz bandwidth. A mirror doubler amplifier achieved a DC gain of 6.8 dB with 86 GHz bandwidth. These amplifiers will be useful for future work in ADCs, DACs, and fiber-optic receivers, and serve to benchmark the transferred-substrate technology.
