A 300 GHz Frequency Doubler in Transferred Substrate InP DHBT Technology
2021 16th European Microwave Integrated Circuits Conference (EuMIC)（2022）
Abstract
A 300 GHz frequency doubler in transferred-substrate InP DHBT technology is presented. The frequency doubler has an unbalanced single ended topology and employs reflector networks for high efficiency. The experimental results show a saturated output power of -1.45 dBm at 296 GHz. The power consumption is only 9.9 mW leading to a record conversion efficiency of ~7% for transistor based sources in this frequency range.
