Este artigo apresenta um deslocador de fase do tipo switch CMOS compacto e de alta resolução (STPS) para a banda n5 da rede móvel de 5ª geração (260G). Neste trabalho, estão incluídos quatro estágios de mudança de fase grosseira e um estágio de sintonia de alta resolução. Os estágios grosseiros baseados na topologia T em ponte são capazes de fornecer cobertura de fase de 202.5° com um passo de sintonia de 22.5°. Para melhorar ainda mais a resolução da mudança de fase, um estágio compacto de ajuste fino cobrindo 23° também é integrado aos estágios grosseiros. A resolução de mudança de fase de sub-grau é realizada para suportar a direção precisa do feixe e a calibração de fase de alta precisão no novo rádio 5G. Algoritmo de controle de fase simplificado e perda de inserção suprimida também podem ser mantidos pelo estágio de ajuste fino proposto. Na medição, os erros de ganho RMS alcançados em 39 GHz são de 0.1 dB e 0.4 dB para os estágios grosso e fino, respectivamente. Os erros de fase RMS alcançados em 39 GHz são 3.1° para os estágios grossos e 0.1° para o estágio fino. Entre 37 GHz e 40 GHz, a perda de retorno medida em todos os estados de sintonia de fase é sempre melhor que -14 dB. O deslocador de fase proposto consome uma área central de apenas 0.12 mm2 com processo CMOS de 65 nm, que economiza área.

Abstract: This paper introduces a high-resolution and compact CMOS switch-type phase shifter (STPS) for the 5th generation mobile network (5G) n260 band. In this work, totally four coarse phase shifting stages and a high-resolution tuning stage are included. The coarse stages based on the bridged-T topology is capable of providing 202.5° phase coverage with a 22.5° tuning step. To further improve the phase shifting resolution, a compact fine-tuning stage covering 23° is also integrated with the coarse stages. Sub-degree phase shifting resolution is realized for supporting the fine beam-steering and high-accuracy phase calibration in the 5G new radio. Simplified phase control algorithm and suppressed insertion loss can also be maintained by the proposed fine-tuning stage. In the measurement, the achieved RMS gain errors at 39 GHz are 0.1 dB and 0.4 dB for the coarse stages and fine stage, respectively. The achieved RMS phase errors at 39 GHz are 3.1° for the coarse stages and 0.1° for the fine stage. Within 37 GHz to 40 GHz, the measured return loss within all phase-tuning states is always better than -14 dB. The proposed phase shifter consumes a core area of only 0.12mm2 with 65-nm CMOS process, which is area-efficient.
