Abstract: According to the communication requirements of multi-vehicle cooperative system, a design method of transceiver-integrated RF device with high isolation, wide dynamic and fast response is provided. This paper discusses the architectural of the transceiver-integrated RF device, and the key indexes as AGC circuit, high isolation, and linearity are designed from the engineering application. A high isolation transceiver-integrated 4×2 RF switch matrix is designed. Through the field test of the system, the test results show that the transceiver isolation index is greater than 99 dB, and the receiving dynamic range is greater than 65 dB. The RF indexes are stable and reliable to meet the needs of multi-vehicle system requirements, which provides a reference method for the further study of the multi-vehicle system data exchange equipment.

引言
随着机载平台的机动性能快速提升,对设备的通信性能也提出了更高要求,其中多机协同通信系统正成为世界各国的研究热点[1-2],如图1所示。该系统以时分多址为基础,并结合频分、空分多址复合机制,利用每个时隙控制波速指向通信对象,能够将平台能力有机整合,载荷功能融入互补,对促进多样化任务执行能力、高效信息共享和协同行动具有重要作用[3-5]。接收和发射设备为该系统的建设提供了硬件基础,同时也对收发设备的性能也提出了更高的要求[6]。目前的收发一体设备为提高收发隔离度、接收系统响应时间等指标性能,采用收发系统独立的方式,存在体积大的缺点[7-10]。
