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.
