Abstract
A 300 GHz amplifier is fabricated using indium-phosphide (InP) double-heterojunction bipolar transistor (DHBT) technology. The cascade chain in the amplifier contains six unit cells each containing a pair of common-base DHBTs in differential configuration. A total of three signal lines run through to the unit-cell to obtain the differential-mode amplifier gain and provide proper dc bias. Measured results show the peak gain of 17.3 dB at 290 GHz with 10-dB gain-bandwidth of 20 GHz.
