摘　　要：为了有效保证广播电视系统的正常工作,发射机必须时刻保持较好的工作状态,这对其硬件性能提出了较高要求。作为PDM 1 kW中波广播发射机的关键部件,射频链路在节目内容安全播出过程中发挥着重要作用。通过研究PDM 1 kW中波发射机的工作原理和射频链路组成,结合射频组成技术原理深入探析其常见故障原因并给出处置策略,为相关人员提供参考。In order to effectively ensure the normal operation of the radio and television system, the transmitter must always maintain a good working state, which puts forward higher requirements for its hardware performance. As a key component of the PDM 1 k W medium wave broadcasting transmitter, the radio frequency link plays an important role in the safe broadcasting of program content. This paper studies the working principle and radio frequency link composition of PDM 1 kW medium wave transmitter, and combines the technical principle of radio frequency composition to deeply analyze the causes of its common faults and give the disposal strategies, providing reference for relevant personnel.
