| In this paper, the information processing technology is designed as the important part of millimeter wave digital communication system. The following functions are realized.1 System internal communication and system external communication are realized.2 To supply LO for upconverter and downconverter.The interface circuits between TMS320LF2407 and the drive components of CAN bus and RS422 bus are designed in this paper. The software is also programmed. So CAN communication and RS422 communication can be realized. Based on the research of PLL frequency synthesizer technology, a 3G PLL frequency synthesizer is designed, and it is controlled by TMS320LF2407. The synthesizer can not only output a single frequency, but also output jumping frequencies. |
