摘要

本文提出了一种基于微带槽线耦合器的宽带、紧凑的36°$36{0}^{\circ}$可调谐反射式移相器。移相器包括一个微带槽线3db耦合器，以及由可变电容器和短于四分之一波长的高阻抗传输线组成的两个相同反射负载。这种结构增加了反射式移相器的带宽，减小了最大插入损耗和插入损耗的波动。测得的移相器回波损耗显示出47.2%的带宽优于10 dB，中心频率插入损耗为1.0 ~ 2.7 dB，最大相移为386.3°${386.3}^{\circ}$。移相器的面积为0.2 λ g × 0.4 λ g$0.2{\lambda}_{g}\乘以0.4{\lambda}_{g}$在3.6 GHz。

Broadband and Compact Tunable Reflection-Type Phase Shifter Based on Microstrip Slotline Coupler

This paper presents a broadband and compact $36 0^{\circ}$ tunable reflection-type phase shifter based on microstrip slotline coupler. The phase shifter consists of a microstrip slotline 3 dB coupler, along with two identical reflected loads made of variable capacitors and high-impedance transmission lines shorter than a quarter wavelength. This structure increases the bandwidth of reflection-type phase shifter and reduces the maximum insertion loss and the fluctuation of insertion loss. The measured return loss of the phase shifter shows a 47.2% bandwidth better than 10 dB, with center frequency insertion loss of 1.0∼2.7 dB and a maximum phase shift of ${386.3}^{\circ}$ . The phase shifter occupies an area of $0.2 λ_{g} \times 0.4 λ_{g}$ at 3.6 GHz.
