一种高频频段发射机防护器的设计

Design of a High-Frequency Band Transmitter Protector

摘要

在电磁环境日益复杂，强电磁脉冲威胁日趋显著的背景下，研究如何有效地保护通信设备免受此类快脉冲、高强度干扰源的影响至关重要。特别是强电磁脉冲很容易通过直接或者耦合的方式进入通信设备里与天线连接的接收机、发射机，导致在强电磁脉冲下极易出现导致其出现故障，或者工作性能降级甚至损毁等一系列问题。针对现有一般防护器在强电磁脉冲防护能力上的不足，本文提出了一种高频频段发射机防护器的设计，分析并采用气体放电管进行防护器的设计。

Abstract

Against the backdrop of an increasingly complex electromagnetic environment and a growing threat from high-power electromagnetic pulses (HPEMPs), it is critical to investigate effective strategies for protecting communication equipment against such fast-rise, high-intensity interference sources. In particular, high-power electromagnetic pulses can easily enter the receivers and transmitters connected to antennas within communication equipment via direct injection or coupling pathways, rendering these devices highly susceptible to malfunctions, performance degradation, or even permanent damage under HPEMP conditions.To address the insufficient high-power electromagnetic pulse protection capabilities of conventional protective devices currently available, this paper presents a design for a protective device applicable to high-frequency-band transmitters. The design employs gas discharge tubes (GDTs) as the core protective component, with detailed analysis and implementation provided.
