Analysis and design of matching network for radio-frequency circuit

During the design of radio-frequency circuit,in order to transmit the most energy of signals and decrease the influence of echo to the signals quality and the available power,match network design is the most important question which must be calculated.At first this article analyzes the working condition of transmission line and the match circuit design theory based on the transmission-line theory,and then describes the methods of matching network in detail,in the end gives the design of matching network and performance emulation by the software of ADS,the result shows the importance of match network design.
