摘要

This article presents a two-channel 70-110-GHz frequency quadrupler in the GF8HP 0.12-μm SiGe BiCMOS process. The ×4 frequency multiplication is based on cascaded frequency doublers with an interstage bandpass filter to reject undesired harmonics. The measured peak output power is -1.5 to 3 dBm at 70-110 GHz, with a worst case harmonic rejection ratio (HRR) of >30 dBc. The chip size is 1.9 mm2 and...
