数量众多的大功率ＢＢ机发射台互调引起的无线电干扰使１５０ＭＨｚ频段无线通信网受到严重干扰，信噪比迅速恶化。文章分析了互调干扰产生的原因，其互调分量与发射天线架设位置的关系以及要解决这类干扰可能采取的措施。本文介绍了两种抗干扰器件，滤波器和单向器，它们的优缺点。文章最后着重介绍了一种抗互调干扰的滤波器和其抗互调能力．
A large number of high-power BB transmitter radio intermodulation caused by radio interference to 150MHz band wireless communications network was severely disrupted, the signal-to-noise ratio deteriorated rapidly. This paper analyzes the causes of intermodulation interference, the relationship between its intermodulation components and the location of the transmitting antenna, and the possible measures to be taken to resolve such interference. This article describes two anti-jamming devices, filters and one-way, their advantages and disadvantages. Finally, the article focuses on a filter that is resistant to intermodulation and its anti-intermodulation capability.
