Abstract
Wideband direct-coupled differential amplifiers utilising AlGaAl/GaAs HBTs are presented. In the new circuit, input and output voltages of 0 V are obtained in a balanced condition, which allows direct cascade connections of the amplifiers. Superior amplifier performance of 20 dB gain with a 9 GHz bandwidth is obtained
