| Abstract: | Based on ADS software,the high effective and power amplifier can be designed after learning the output and input impedance characteristic of the LDMOS transistor BLF7G22L130 by Load-pulling method under an appropriate static DC point and realizing the best conjugate match network through design and optimizing.ADS simulation indicates that the effectiveness of this kind of amplifier reaches 70% at the center frequency of 2 160 MHz,with the advantages of high stability and low gain flatness. |
