Design of Automatic Level Control for Microwave Signal Source

摘要：

　　The performance of the automatic level control(ALC) system determines the stability of the microwave signal source output power, accuracy and linear flatness in each frequency range, directly determining the signal generator power characteristic indicators.This paper gives an implementation of a high-performance feed-forward ALC circuit, the negative feedback loop consists of the power detector circuit, logarithmic amplifier, the integral hold circuit, attenuator driving circuit, PIN attenuation circuit and so on.

关键词： ALC Power divider and detector Logarithmic amplifier PIN attenuation circuit
