The Research And Impementation In Logic And Control System Of High-Performance Wireless Communication Transceiver

High-performance wireless communication transceiver is the key part of RF Test Instrument. Its precision and sensitivity are very important to the overall performance, and also the difficulty during the research and development.The thesis presents the work of the project of RF universal module. The RF universal instrument can meet the requirements of the GSM, all 3Q TD-LTE standard. The RF universal module can be divided into three parts:the clock part, the RF trancerver part, and the logic and control part.The anthor is mainly responsible for the logic and control system part. This part completes the control, AD and DA conversion of the transmit and receive signals links.The anthor's work covers requirements analysis, outline design, detailed design, schematic design, PCB design and debugging. Several problems have been sovled by the author, such as the design and implementation of the high-performance ADC and DAC circuit, high-speed serial bus circuit, high-density FPGA circuit.The main structure of this thesis is as follows:1. Based on the overall framework of high-performance RF universal module and the outline design of the logic and control system, choose the core chip of the logic and control board.2. Introduces the detailed design about the hardware of the logic and control system.3. Describes the PCB structure, the PCB layout, and the test results of the ADC circuit.4. Sum up the work and the problems done by the author.
