The Analysis of Impedance Matching Problem in RF Circuit Design

The impedance matching is a key problem in RF circuit design. In order to enable the radio frequency power to inject into the load, to realize the transmission of power in high efficiency, the impedance matching technology must be adopted. The Article firstly analyzes the extra power loss and extra distortion when impedance doesn't match, the extra power loss caused by the non-matching of circuit design will have serous influence to the performance of communication system and other systems, as well as the common circuit structure used for designing impedance matching and its advantages and disadvantages, and too many components in matching network will bring serious attenuation to the signals. providing relevant referring solutions for RF circuit designers to solve the same problems.
