900MHz频段射频功率放大器匹配网络设计

In this paper, it has been introduced that the matching network design of RF power amplifier and the technical difficulties of the basic principles. Meanwhile, a new method of calculating the complex impedance,which is more effctive, is propoed.The paper practices the methods of matching network design and the key technology is analyzed.Using Freescale's MRF5S9070NR1 of Power amplifier CMOS chip for the sample, the dual audio testing-which is generated by a RF signal generator-is performed, according to the reference chip DATASHEET parameters . The test data are shown by the Spectrum Analyser and recorded.Finally,the differences of theoretical data and testing data are compared,and the conclusion is given.
