State-of-the-art THz integrated circuits in InP HBT technologies

In this paper, state-of-the-art terahertz (THz) integrated circuits in InP HBT technologies operating in the 500–600 GHz band are reviewed: the highest-frequency fundamental transistor oscillator, THz power amplifier in HBT with the highest saturated output power, the highest-frequency dynamic frequency divider, and the highest-frequency transmit/receive front-end integrated circuits, to the best of authors' knowledge.
