| Abstract: | This paper presents the design of a drive stage amplifier for RFID system, which works at 902 MHz～928 MHz, output power is 15 dBm, power gain is up to 28 dBm. In order to shorten the research period of power amplifier and succeed to exploit power amplifier rapidly, we shows a kind of approach that simulation optimization combines with practical test to design PA rapidly and successfully. Test the amplifier at practical condition, the highness consistency between practical test and simulation optimization proves the presented method. |
