| 摘 要： | 本文阐述了射频功率自动校准系统的设计。本系统把固态功率放大器、高精度功率计融合为一体，并由μC／OS—Ⅱ实时操作系统控制；界面全汉化显示，方便用户操作。该系统具有校准带宽跨度大、输出功率高、频响特性好等特点，可以对1w—100W之间的射频功率进行快速、准确的校正。由于使用该系统对功率进行校准时不需要使用衰减器，这在很大程度上提高了射频功率校准的精度。

| Abstract: | This paper introduces an auto-calibration system of the RF power. The system integrates the solid-power amplifiers with a high-precision power meter and is under the control of the μC/OS-Ⅱ real-time operating system. The interface display is in Chinese. The system has a large bandwidth span, a high output power and a good frequency response characteristics, can give a fast and accurate calibration on RF power between 1W- 100W. Without the use of the calibrated attenuator the RF power-calibration accuracy is also improved. |
