Abstract
This paper presents a highly-efficient on-chip W-band single-diode rectifier for energy recovery in 6G transmitters and wireless power transfer applications. For the first time a W-band rectifier has been fabricated on an InP HBT process. The circuit consists of a 2 x (0.85 x 6 μm2) series p-n diode as the core rectification element and a big shunted capacitor. No input matching has been applied. At 108 GHz the rectifier achieves a measured record power conversion efficiency (PCE) of 69% for - 1.5 dBm RF input power (RFin). The PCE reaches 14 % for RFin of about 15 dBm with 5 mW of DC output power. The chip shows a very compact size with 360 x 260 μm2 including pads.
