摘要

摘要: 功分网络用于将HPM分成若干路后馈入移相器、单元天线等，其中过模圆波导到多路矩形波导功分器同时具有模式转换和功率分配功能，需具备高功率容量、高传输效率、低反射等特性。针对Ku波段GW级过模圆波导到8路矩形波导功分器，开展了设计、仿真、研制和小信号测试，建立了功率容量测试平台，对其功率容量进行了考核。小信号测试结果表明，该1分8路功分器，在14.7 GHz±200 MHz范围内，反射系数小于−20 dB，传输系数−9.1 dB左右，端口不平衡度小于0.4 dB；功率容量考核实验表明，该功分器功率容量超过900 MW。

Abstract: The power division network is one of the key components of high power microwave (HPM) phased array antenna. It is used to divide HPM into several paths and feed it into phase shifter and element antenna. In such a network, the over-mode circular waveguide to multi-channel rectangular waveguide power divider has the function of mode conversion and power distribution. It is the front end of the power division network and requires high power handling capability, high transmission efficiency and low reflection. In this paper, the design, simulation, fabrication, and small signal test of the power divider from Ku-band GW-level over-mode circular waveguide to 8-channel rectangular waveguide were carried out. Subsequently, the power handling capacity of the power divider was evaluated utilizing the established power capacity testing facility. The experimental outcomes demonstrated that within the frequency band of 14.7 GHz±200 MHz, the reflection coefficient was consistently below −20 dB, the transmission coefficient exceeded −9.1 dB, the port imbalance was maintained at less the 0.4 dB, and the power handling capacity exceeded 900 MW.
