摘要

本文介绍了一种用于s波段卫星通信链路的低损耗窄带波导双工器的设计。将讨论超窄带(Δ约0.2%)滤波器的设计及其在双工器设计中的应用。所制备的双工器具有低损耗性能(每个通道最大1.3 dB和1.8 dB插入损耗)，适合于对地静止卫星传输的窄带信号信道化。

Dual-Mode Waveguide Cavity Filters and Diplexer With Fractional Bandwidths Around 0.2%

This work presents the design of a low-loss narrowband waveguide diplexer for S-band satellite communication links. The design of ultra-narrowband (Δ around 0.2%) filters will be discussed as well as their applications to diplexer design. The fabricated diplexer exhibits a low-loss performance (max 1.3 dB and 1.8 dB insertion loss in each channel), and it is suited for channelizing narrow-band signals transmitted from geostationary satellites.
