Telemetry miniature transmitter is the sensing device, a major part, of the Internet of things. The design of the telemetry miniature transmitter according to FPGA not only has the characters of high integration, strong calculation and low power consumption, but also features high agility and strong actual effect. According to the overall system requirements, the design method and process for FPGA circuit is established, and its system circuit test proves that it meets the actual requirement. The target communication parameters are conveniently allocated through the configuration circuit, which can be upgraded through software upgrade. The target identity can be easily recognized. It is applicable to the common use.
