Design of Broadband Microstrip Equalizer

摘要

Equalizers are common microwave devices often used to improve the problem of unsatisfactory signal amplitude-frequency characteristics in microwave systems. This paper briefly introduces the basic principles of the equalizer, and brings up the equalizer designing method: based on the uneven signal amplitude-frequency characteristics, use the theoretical analysis to design the initial value, and perform computer simulation optimization, and develop the X-band microstrip equalizer. The test results show that the equalizer's equalization in the working frequency band is about 4dB, and the input and output standing wave coefficient is less than 1.5, which meets the system's designing requirements for equalization, standing waves and miniaturization.
