| Abstract: | A 6-carrier CDMA800 high linear power amplifier(PA)was designed in this paper.Based on the unconditional stability of the Transistor,4-stage microwave power amplifier was successfully designed.We combined Loadpull and Sourcepull technology to get the best input and output matching circuit.Its maximum output power is over 42 dBm,power gain is 50dB,the IMD3 is less than-47dBc.ACPR and PAE also reached the standard of telecommunication systems.Double-balanced circuit was used in the last stage to improve on th... |
