摘　　要：针对小型飞行器在飞行过程中工作状态参数的测试需求,设计了一种基于FPGA的小型化宽带零中频微波发射系统。该系统以FPGA为主控单元,接收飞行器上传感器的参数,通过正交上变频模块,实现QPSK调制,完成对所需频段微波信号的输出。经测试,该发射机输出的调制信号频率可达到4 000 MHz,功率可达到10 dBm,各项参数满足设计要求,能够实现数据的高速传输。According to the test requirements of working parameters of small aircraft during flight,a miniaturized broadband zero-IF wireless transmitting system based on FPGA is designed. The system takes the FPGA as the main control unit,receives the parameters of the sensor on the air vehicle,and completes the output of the RF signal of the required frequency band through QPSK modulation and a reasonable up-conversion module. After testing,the transmitter output modulation signal frequency up to 4 000 MHz,power up to 10 dBm,the various parameters meet the design requirements,enabling high-speed data transmission.
