| Abstract: | Wireless Transmission System is widely used in various situations, and it＇s important to research its RF front-end. It includes a filter module, the mixer module, the amplifier module and power amplifier modules, antenna modules, and facilitating for processing of digital IF of 10.7 MHz which produced by the digital IF module of FPGA, and getting a 433.92 MHz RF signal with a certain power that launching effectively. Finally, it debugged and tested with each module, verified the correctness of the RF front-end, and realized the sound signal of conversion and the emission was produced by the digital IF module of FPGA. |
