摘要

作为保证无源互调(PIM)测试精度的关键环节，PIM测试仪的PIM校准受到了广泛关注。本文提出了三种实现PIM校准标准源可调的方案，用于PIM测试仪的校准。应用了两种类型的非线性源，并开发了三种电路或腔结构来控制这些源。通过使用不同的策略，所提出的PIM源可以生成不同范围的可控PIM引用，覆盖大多数PIM测试范围。在实验中，评估了PIM信号的稳定性以及PIM的动态范围。PIM的最小波动小于1dB，而最大动态范围可达50dB。由于这些解决方案具有不同的尺寸和功能，可以根据不同的测试需求进行使用，并且很容易与PIM测试仪集成。这些解决方案可以帮助开发新一代的PIM测试器。

Tunable Intermodulation Generator for Passive Intermodulation Tester Calibration

As a key step to guarantee passive intermodulation (PIM) test accuracy, PIM calibration for PIM tester draws great attention these days. This paper provides three solutions to realize tunable PIM calibration standard sources for PIM tester calibration. Two types of nonlinearity sources are applied while three circuit or cavity structures are developed to control these sources. By using different strategies, the proposed PIM sources can generate controllable PIM references with different ranges that cover most PIM test ranges. In the experiments, the PIM signal stability is evaluated as well as PIM dynamic range. They show the minimal PIM fluctuation as less as 1dB, while the maximal dynamic range can reach 50dB. As these solutions have various sizes and function, they can be utilized according to different test requirements and easily integrated with PIM tester. These solutions can help develop new generation of PIM testers.
