The future war is a digital war integrating all kinds of forces,such as sea,land,air and sky,and taking information chain as a link.The characteristic of the digital information war is that each unit of the armed forces is a pivot of information,and all the pivot points are connected to each other to form an information network,and the information network fulcrum requires real-time and transparent information.Therefore,the information war on arms in each combat unit node information sharing,put forward high requirements of real-time.The communication radio,which is supported by the information war,should realize the seamless communication between the information between the military and the armed forces and the internal forces of all kinds of armed forces in the information war,and realize the rapid and real-time sharing of information as the basic task.The digital information battlefield is the timely acquisition,timely sharing and timely command of information,so that the efficiency of the battlefield is optimized and the reliable communication can be achieved in the complex electromagnetic environment.However,as the mainstay of the information war,the military active service radio station,which is designed for the specific military or specific use environment,has a wide variety,poor compatibility,difficult interoperability and poor anti-interference ability,and it is difficult to support the need of information warfare in digital troops.In order to meet the needs of information warfare,the communication broadband high-speed radio is developing towards multi band,multi-mode,digitalization and software.Transceiver is the core and key part of transceiver,which is the core and key part of the transceiver.Many functions,performance requirements and transceiver design are closely related.So,in order to meet the needs of the radio,transceiver must have an open and programmable broadband RF front end design,switching multi bandwidth medium frequency design,high dynamic and fast switching.The frequency synthesizer and fast AGC control channel are designed to facilitate the operation of various software waveforms.This paper designs a transceiver with multi frequency,high dynamic,miniaturized and low power consumption.It can adapt to a variety of digital transmission systems and high speed data transmission in multiple modes.It can adapt to the demand of anti-interference in the environment of complex radio and can meet the needs of network networking.According to the actual use demand of customer radio,the transceiver adopts multi bandwidth and multi rate mode,which can not only achieve high data rate,accomplish large data transmission demand,but also reduce the use of communication resources in low data,improve receiver sensitivity,extend communication distance of communication equipment and meet the needs of long-distance communication.The transceiver adopts integrated design idea and wide frequency.Segment,low power and miniaturized devices,realize multi frequency,multi mode and multi task performance,reduce the type of radio and reduce the volume of radio.The transceiver also adopts serial and universal design,which can meet the use of handheld,back and vehicle radio,and improve the compatibility and generality of radio. |
