18.5 GHz bandwidth monolithic preamplifier using AlGaAs/GaAs ballistic collection transistors

A circuit technique for improving the transimpedance flatness and output matching characteristics in a preamplifier is proposed. An 18.5 GHz bandwidth monolithic preamplifier with a transimpedance of 52dBΩ has been fabricated with AlGaAs/GaAs ballistic collection transistors.
