본 논문에서는 위성 통신(SATCOM)을 위한 비균일 매칭 기술을 갖춘 고해상도 및 저삽입 손실 CMOS 하이브리드 위상 천이기에 대해 제시합니다. 제안된 하이브리드 위상 천이기에는 45개의 45° 대략 위상 천이 단계와 45개의 0.8° 미세 위상 천이 단계가 포함됩니다. 거친 스테이지는 29° 위상 단계를 갖춘 브리지 T 스위치형 위상 천이기(STPS)에 의해 구현됩니다. 미세 조정 단계는 위상 조정을 위한 두 개의 동일한 LC 로드 탱크가 있는 반사형 위상 천이기(RTPS)를 기반으로 합니다. SATCOM의 미세 빔 조향을 지원하기 위해 이 작업을 통해 0.7° 위상 분해능이 실현되었습니다. 체인 삽입 손실을 더욱 줄이기 위해 거친 단계에서는 불균일 매칭 기술이 사용됩니다. Coarse 및 Fine 스테이지의 경우 0.3GHz에서 측정된 RMS 이득 오류는 각각 0.8dB 및 0.4dB입니다. 측정된 RMS 위상 오류는 각각 12°와 24°입니다. 제안하는 하이브리드 위상 천이기는 34GHz부터 65GHz까지 모든 위상 상태의 반사 손실을 -0.14dB 미만으로 유지한다. 제시된 하이브리드 위상 시프터는 XNUMXmm의 표준 XNUMXnm CMOS 기술로 제작되었습니다.2 활동 영역.

Abstract: This paper presents a high-resolution and low-insertion-loss CMOS hybrid phase shifter with a nonuniform matching technique for satellite communication (SATCOM). The proposed hybrid phase shifter includes three 45° coarse phase-shifting stages and one 45° fine phase-tuning stage. The coarse stages are realized by bridged-T switch-type phase shifters (STPS) with 45° phase steps. The fine-tuning stage is based on a reflective-type phase shifter (RTPS) with two identical LC load tanks for phase tuning. A 0.8° phase resolution is realized by this work to support fine beam steering for the SATCOM. To further reduce the chain insertion loss, a nonuniform matching technique is utilized at the coarse stages. For the coarse and fine stages, the measured RMS gain errors at 29GHz are 0.7dB and 0.3dB, respectively. The measured RMS phase errors are 0.8° and 0.4°, respectively. The proposed hybrid phase shifter maintains return losses of all phase states less than -12dB from 24GHz to 34GHz. The presented hybrid phase shifter is fabricated in a standard 65-nm CMOS technology with a 0.14mm2 active area.
