摘要

提出了一种紧凑连续可调谐360°移相器的设计方法。该结构由一个180°反射型移相器（RTPS）和一个180°开关型移相器（STPS）级联组成。RTPS由基于变压器的90°耦合器和Γ-π反射负载组成。STPS由变压器和单极双掷（SPDT）组成。为了实验验证，设计并制作了一个中心频率为1.5 GHz的紧凑连续可调谐360°PS。从测量结果来看，所提出的360°PS提供了0°-360°的可调相移范围（PSR），插入损耗（IL）为2.85±0.7 dB，电路尺寸为0.031 λg2。

A Compact and Continuously Tunable 360° Phase Shifter Using Cascaded Transformer-Based 180° Reflection-Type and Switched-Type Phase-Shift-Cell

This article presents a design method for compact and continuously tunable 360° phase shifter (PS). The proposed structure consists of a 180° reflection-type phase shifter (RTPS) cascaded with a 180° switched-type phase shifter (STPS). RTPS consists of a transformer-based 90° coupler and Γ-π reflection loads. STPS consists of a transformer and a single-pole double-throw (SPDT). For experimental verification, a compact and continuously tunable 360° PS with a center frequency of 1.5 GHz was designed and fabricated. From the measurement results, the proposed 360° PS provides a tunable phase shift range (PSR) of 0°–360°, with an the insertion loss (IL) of 2.85 ± 0.7 dB, which has a circuit size of 0.031 λg².
