Abstract
A high-power terahertz solid-state amplifier fabricated using 0.25 mu m InP heterojunction bipolar transistor (HBT) technology is reported. This amplifier utilies a novel defective-ground four-way balun to combine differential amplifier chains for a total output device periphery of 40 mu m. A significant amount of power of similar to 10 mW is obtained at 305 GHz with better than 20 dB small-signal gain.
