PIN Diode-Based Frequency Doubler for D-Band Applications

This paper explores the potential of pin-diode-like structures for frequency multiplication, focused on doubling, in a well-established commercial SiGe BiCMOS technology. These devices can be manufactured without additional costs by omitting the characteristic implant of the junction varactor layout. Measurement results confirm a pronounced step recovery behavior and the usability of these structures for frequency doubling. A VCO implementation operating around 130 GHz with an output power up to 0 dBm successfully demonstrates the efficient doubling of a fundamental frequency into the D-band.
