Abstract

In this paper, we propose and demonstrate a new four-port BPSK direct conversion receiver based on $0.18\;{\mu}m$ CMOS technology for K-band applications. The proposed direct conversion receiver is composed of two active combiners, an lumped LC balun, two power detectors and an analog decode. The designed direct conversion receiver is successfully demodulated BPSK signal with 40 Mbps in the K-band.

본 논문에서는 K-band 응용을 위한 $0.18\;{\mu}m$ CMOS 공정을 기반으로 한 새로운 방색의 four-port BPSK 직접 변환 수신기를 제안하고 검증한다. 제안한 직접 변환 수신기는 두 개의 능동 결합기, 집중 소자 LC 발룬, 두 개의 전력 검출기, 그리고 아날로그 디코더로 구성되어 있다. 설계된 직접 변환 수신기는 K-bnad 반송파 주파수의 데이터율 40 Mbps까지의 BPSK 변조 신호를 성공적으로 복조하였다.
