This letter discusses the development of a 177–205 GHz CMOS synthesizer module to support planetary science THz instrumentation. The developed synthesizer chip employs a CMOS system-on-chip device containing a 50 GHz phase-locked loop with programmable divider and both 100 and 200 GHz frequency doublers to provide the output carrier. The chip also contains a power sensor for calibration of output power and a dosimeter and thermometer for environmental monitoring of radiation and temperature. The chip is integrated into a board with a microcontroller and USB interface for providing frequency commands and sensor readback. The module is shown to deliver at least 10 μW across the 177–205 GHz lock range while consuming 249 mW of dc power.
