Recent advances in MMIC-based solutions dedicated to imaging and sensing applications in the atmospheric windows located around 140, 200 and 300 GHz are presented. The MMICs comprise the individual components of a typical architecture of heterodyne analog frontends, and their combination into MMICs performing several functionalities or with full receiver capability. We discuss low-noise amplifiers up to 300 GHz, frequency multipliers and mixers operating up to 300 GHz, a power amplifier MMIC achieving more than 11 dBm of output power at 140 GHz, and a 200 GHz multi-functional, heterodyne receiver MMIC driven by a subharmonic local oscillator signal with low power requirements.
