摘　　要：为了获得更好的传输能力和抗干扰能力,提出了一种双载波收发信机的设计思路。采用矢量乘法器和正交解调器等通用芯片进行了电路实现,给出了上下行链路射频变换部分的实现方法和技术要点。对发射单元和接收单元进行了仿真,并对电路进行了优化。结合电路实现和测试,验证了接收端正确分离、解调2路载波上调制信号的能力。提供了一种在降低系统复杂度、减小体积功耗要求的前提下,增加系统接收能力和应用灵活性的设计与实现方法。To acquire the capabilities of stable transmission and anti-interference,this paper puts forward a design concept of double-carrier transceiver. The circuit design is implemented by using vector multiplier and quadrature demodulator. The implementation method and technical parameters of RF transformation in uplink and downlink are presented. The simulation is performed for transmitting unit and receiving unit,and the optimization is performed for circuit. The test results show that the data can be received correctly from the two carriers,and the system can meet the expected requirement of specifications. The design not only simplifies the complexity of the system,decreases the volume and power consumption,but also improves the receiving capability and application flexibility.
