Abstract

An ultra-wideband transmitter MMIC based on a single-balanced mixer circuit for high-speed communication systems around 300GHz has been successfully realized in a 35nm mHEMT technology. Besides the single-balanced mixer cell, the transmitter comprises a frequency tripler followed by a buffer amplifier in the LO path as well as an RF post-amplifier on a single chip. Chip measurements show an output power above 0 dBm, paired to a conversion gain of 0 dB and a 3-dB IF bandwidth of 40GHz for the transmitter MMIC, which makes it a perfect candidate for the next generation of 100 Gbit/s indoor communication systems.
