Cluster Communication Base Station Receiver System Rf Front-end Design And Development

This article in-depth analyses the key technical indicators of receiver RF front-end at first, and then introduces the design methods. After that, the implementation of each characteristic and some questions paid more attention to system design and tuning, more details are dicussed in the paper. Trunking communication system is an advanced wireless scheduling command system which shares resources, costs, and provides users with excellent services, multi-purpose, high performances and low-cost. It is suitable for higher enterprises, utilities, mining, oil fields, farms, public security, armed police and army and other departments who demands high scheduling function.This thesis studies the allocation of public security system which uses 350MHz police band with special trunking communication system base station receiver RF front-end. Cluster system is a multi-functional, efficient and large-capacity advanced wireless dispatch communication system. It's a dedicated business wireless dispatch system with wired switching, computer technology and ultra large scale integrated circuit product of the combination. Because of the acceptance of front-end system performance indicators for the overall performance, the system indicators for the upper limit of the circuit behind the development of good front-end circuit of the receiving system are inevitable requirements in order to improve the whole system.This issue is based on the recent technology in and aboard, researches design theory and engineering practice of the trunking communication system base station receiver RF front-end. The article first analyses the key technical indicators of the receiver RF front-end, the design and demonstration programs in the 350MHz trunking communication base station receiver system, the design of phase-locked loop frequency source and filter is also discussed in this paper, including the low noise amplifier circuit. After that, the implementation of each characteristic and some questions paid more attention to system design. The ultimate testing results of this subject are represented in the end.
