摘　　要：通过搭建谐振电路的方法对国产磁合金环性能进行了测试。测试的主要参数包括磁合金环的磁导率、Q值及其并联阻抗值等。测试结果表明:该磁合金环的Q值很低,随频率的变化不明显;磁导率很大,随频率的增加而减小;并联阻抗值随频率增加而变大。在100℃温度以内,其性能参数变化很小。The key to design magnetic alloy （MA） loaded cavity is to test and research the performance parameter of the MA core. Using the resonant circuits, we have tested the performance parameters of the domestic MA core, including the permeability, Q value and shunt impedance. Test results show that the Q value of the MA core is low while the change caused by frequency is not obvious. The magnetic permeability is high and decreases with frequency increase while the shunt impedance increases with frequency increase. Within the working temperature from 0 ℃ to 100 ℃, the performance parameter of the MA core changes very little. The analysis of the performance test data of the MA core provides important technical indexes for the design of microwave power source and LLRF system.
