Cet article présente un déphaseur hybride CMOS haute résolution et à faible perte d'insertion avec une technique d'adaptation non uniforme pour les communications par satellite (SATCOM). Le déphaseur hybride proposé comprend trois étages de déphasage grossier à 45° et un étage de réglage de phase fin à 45°. Les étages grossiers sont réalisés par des déphaseurs de type commutateur en T ponté (STPS) avec des pas de phase de 45°. L'étage de réglage fin est basé sur un déphaseur de type réfléchissant (RTPS) avec deux réservoirs de charge LC identiques pour le réglage de phase. Une résolution de phase de 0.8° est réalisée par ce travail pour prendre en charge l'orientation fine du faisceau pour le SATCOM. Pour réduire davantage la perte d'insertion de chaîne, une technique d'appariement non uniforme est utilisée aux étapes grossières. Pour les étages grossiers et fins, les erreurs de gain RMS mesurées à 29 GHz sont respectivement de 0.7 dB et 0.3 dB. Les erreurs de phase RMS mesurées sont respectivement de 0.8° et 0.4°. Le déphaseur hybride proposé maintient les pertes de réflexion de tous les états de phase inférieures à -12 dB de 24 GHz à 34 GHz. Le déphaseur hybride présenté est fabriqué dans une technologie CMOS standard de 65 nm avec un objectif de 0.14 mm.2 zone active.

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.
