摘要

本文针对目前衰减器插入损耗高和衰减精度低的问题，提出了一种基于射频微机电系统（MEMS）开关的三通道可重构阶跃衰减器。共面波导（CPW）、十字形功率分配器、射频微机电系统（MEMS）开关和 π 型衰减电阻网络被设计为衰减器的基本单元。衰减器通过两个基本单元在 1~25 GHz 频率范围内以 5 dB 的间隔实现了 0~30 dB 的衰减。结果表明，插入损耗小于 1.41 dB，衰减精度优于 2.48 dB，几何尺寸为 2.4 mm × 4.0 mm × 0.7 mm。该衰减器可应用于雷达、卫星、航空航天、电子通信等众多领域。

The Seven-State RF MEMS Miniaturized Broadband Reconfigurable Step Attenuator.

This paper presents a three-channel reconfigurable step attenuator based on radio frequency (RF) microelectromechanical system (MEMS) switches, in response to the current issues of high insertion loss and low attenuation accuracy of attenuators. The coplanar waveguide (CPW), cross-shaped power dividers, RF MEMS switches, and π-type attenuation resistor networks are designed as a basic unit of the attenuator. The attenuator implemented attenuation of 0~30 dB at 5 dB intervals in the frequency range of 1~25 GHz through two basic units. The results show that the insertion loss is less than 1.41 dB, the attenuation accuracy is better than 2.48 dB, and the geometric size is 2.4 mm × 4.0 mm × 0.7 mm. The attenuator can be applied to numerous fields such as radar, satellites, aerospace, electronic communication, and so on.
