【摘要】 介绍了接收天线和混响室本身的无源互调测试方法,通过比较二者无源互调的相对值验证混响室测试结果的真实性。在不同状态下测试混响室的无源互调信号,测试结果对比表明:接触非线性是铝板拼接混响室产生无源互调的主要因素。更多还原

【Abstract】 The passive intermodulation testing method of receiving antenna and reverberation chamber itself is introduced. The validity of test results of reverberation chamber is verified by comparing the relative values of two passive intermodulation tests. The passive intermodulation signals of reverberation chamber were measured in different states. Comparison of test results shows that contact nonlinearity is the main factor of passive intermodulation in aluminum splicing reverberation chamber.更多还原
