Abstract

In this paper, a K-Band binary phase shifter that utilizes the architecture of a 180° rat-race coupler is presented. This structure takes advantage of the phase delay inherent in the coupler, along with fast switching PIN diodes, to create a binary system that has constant power usage and low insertion loss in its active states. The relative phase shift between states is controlled by forward and reverse diode bias voltages and the coupler exhibits binary phase states with absolute phase errors of ±10° over a 5.72 GHz bandwidth, making it suitable for use in K-band applications such as PMCW radar.
一种k波段宽带二进制移相器
本文提出了一种利用180°大鼠竞赛耦合器结构的k波段二进制移相器。这种结构利用了耦合器固有的相位延迟,以及快速开关PIN二极管,以创建一个在其活动状态下具有恒定功率使用和低插入损耗的二进制系统。状态之间的相对相移由正向和反向二极管偏置电压控制,并且耦合器在5.72 GHz带宽上显示绝对相位误差为±10°的二元相位状态,使其适合用于k波段应用,如PMCW雷达。
