An S-band PA Module Suitable for Spaceborne Measurement and Control Terminal

This paper presents an S-band power amplifier (PA) module suitable for spaceborne measurement and control terminal. It adopts automatic level control (ALC) to ensure the stability of output power, and supports continuous and pulse operation modes. The measured and experimental results show that the output power of the PA module varies from 40.2dBm to 40.8dBm when the input power changes in the range of 0-15dBm. Long-term power consumption can also be greatly reduced by using the power supply modulation circuit. In addition, considering autonomous control, the components in the PA module are 100 percentage of home-made parts.
