Abstract:

This Letter presents a 300 GHz signal source, realised using an 800 nm transferred-substrate InP double heterojunction bipolar transistor process. The source is based on an active frequency tripler. It delivers -1.6 dBm peak output power at 306 GHz. The DC consumption is only 36 mW, which corresponds to 2% conversion efficiency. The measured tripler achieves more than 30 GHz bandwidth and exhibits very low unwanted harmonics. The chip area of the source is only 0.94 × 0.84 mm2.
