Abstract (in Japanese) (See Japanese page) 
(in English) In this work, an ultra-compact wireless receiver chip set employing heterojunction bipolar transistor (HBT) were developed for application to Ku-band wireless communication system. The receiver of monolithic microwave integrated circuit (MMIC) includes mixer, filter, amplifier and input/output matching circuit. Especially, spiral inductor structures employing SiN film were used for a suppression of LO and its second harmonic leakage signals. The ultra-compact active 90。ニ power divider employing InGaP/GaAs HBT was developed for highly integrated on-chip MMIC, and it used a novel composite structure employing common-emitter (CE) and common-collector (CC) circuits for 90。ニ power splitting. The ultra-compact MMIC receiver system showed a highly suppressed LO leakage power of -35 dBm and second harmonic LO leakage power of -53 dBm without external filters. And the size of ultra-compact active 90。ニ power divider was about 31.6% of conventional passive branch-line coupler. The ultra-compact active 90。ニ power divider showed good RF performance comparable to passive divider at Ku-band.
