| Abstract: | In this paper, high-performance feedforward ALC system is designed according to the requirements for high accuracy and wide dynamic range of ALC system in a microwave signal generator. This system is consisted of a directional coupler, a detector, a logarithmic amplifier, a loop integrator, an exponential amplifier and a linear modulator. This paper discusses the characteristics of the sets, the influences on a microwave signal generator and the relevant resolving ways. And the main specifications are listed. In the application, ALC system can meet the design need. |
