Abstract: The signal amplitude stabilizer is usually applied in the mid-power standard to decrease the mismatch error. A new amplitude stabilizer used in mid-power standard is presented in this paper. The configuration and the circuit diagram are introduced firstly, and then every function module of the amplitude stabilizer also gets detailed analysis. The measurement results show the validity for the amplitude stabilizer presented above. Now this new kind of amplitude stabilizer has achieved good application in mid-power measurement.

Key words: Mid-power standard, Amplitude stabilizer, Mismatch
