摘　　要：文章以集成电路通信接收机的互调响应抗扰性、杂散响应抗扰性存在不足,而传统电路通信接收机陶瓷器件在跌落过程中容易受损以及满足多种通信制式时占用电路板面积大的劣势,结合GB/T 32659-2016专用数字对讲机设备技术要求和测试方法、中国铁路总公司印发的铁总运[2017]71号文件《铁路专用数字对讲机设备暂行技术条件》技术指标要求,设计基于AK2365A的通信接收机满足国标和铁路部门的技术要求。文中设计的通信接收机典型特点是兼有集成电路通信接收机的寄存器调整指标的便利和传统电路通信接收机的优秀指标的灵活性,高可靠性。该设计的通信接收机方案适用于数传电台、数字对讲机、模拟对讲机、公众对讲机等专业调频通信机,可广泛应用于铁路、民航、公安、石油、工控、灾害救援等行业和场景。In this paper, the immunity of inter-modulation response and spurious response of integrated circuit communication receivers are insufficient. However, the ceramic devices of traditional circuit communication receivers are easily damaged during the drop process and occupy the area of the circuit board when satisfying multiple communication standards are great disadvantages, combined with technical requirements and test methods for GB/T 32659-2016 digital walkie-talkie equipment, and technical indicators issued by Rail Corporation of China Railway Corporation [2017] No. 71＂Provisional technical conditions for railway digital walkie-talkie equipment＂. The communications receiver based on AK2365 A-is designed to meet the technical requirements of the national standard and railway departments. The communication receiver designed in this paper is typically characterized by the convenience of the register adjustment index of the integrated circuit communication receiver and the flexibility of the excellent indicators of the traditional circuit communication receiver and high reliability. The communication receiver scheme designed in this paper is applicable to professional FM communication machines such as digital radios, digital walkie-talkies, analog walkie-talkies and public walkie-talkies. It can be widely used in railways, civil aviation, public security,petroleum, industrial control, and disaster relief industries and scenes.
