Wireless Transmission System of RF Front-end Design

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.
