标准范围

IEC 62037-1:20 25涉及无源RF和微波组件互调（IM）电平测量的一般要求和测量方法，这种互调可能是由两个或多个发射信号的存在引起的。本文档中给出的测试程序给出了使用两个发射信号表征不需要的IM信号电平所需的一般要求和测量方法。IEC 62037系列涉及PIM的测量，但不涵盖产品性能的长期可靠性。这第三版取消并取代了2021年出版的第二版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:a)增加了PIM生成通常依赖于频率的澄清，并注意到使用扫描或多个固定频率进行测试通常会提供更准确的结果；b)确定多端口PIM分析仪作为可能的测试设置拓扑；c)增加了测试功率水平不超过DUT功率处理能力的规范；d)更新测试规范以包括正确定义PIM测试所需的缺失参数；e)增加了PIM测试报告包括测试持续时间内测量的最大PIM值的说明；f)更正了IEC 62037-1:20 21中错误更改的图3中的错误。

IEC 62037-1:2025 deals with the general requirements and measuring methods for intermodulation (IM) level measurement of passive RF and microwave components, which can be caused by the presence of two or more transmitting signals. The test procedures given in this document give the general requirements and measurement methods required to characterize the level of unwanted IM signals using two transmitting signals. The IEC 62037 series addresses the measurement of PIM but does not cover the long-term reliability of a product with reference to its performance. This third edition cancels and replaces the second edition published in 2021. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) added clarification that PIM generation is typically frequency dependent and noted that testing with swept or multiple fixed frequencies often provides more accurate results;
b) identified multi-port PIM analyzers as a possible test set-up topography;
c) added specification that test power level does not exceed the power handling capability of the DUT;
d) updated test specification to include missing parameters needed to properly define a PIM test;
e) added clarification that PIM test reports include the maximum PIM value measured over the test duration;
f) corrected error in Figure 3 that was erroneously changed in IEC 62037-1:2021.
