Frequency switching method for medium-wave antenna matching network

The invention discloses a frequency switching method for a medium-wave antenna matching network. It is specific to a condition that different antenna matching networks are required by different frequencies, capacitive parameters and inductive parameters of the antenna matching network are adjusted in a switch switching manner so as to achieve the purpose of rapid switching of the antenna matching network. The frequency switching method specifically comprises the following steps that the antenna matching network of a medium-wave transmitter is formed by capacitors, inductors and radio frequency diverter switches; and the capacitive parameters and inductive parameters, which satisfy requirements of different frequencies, in the antenna matching network are chosen by controlling the on and off of the radio frequency diverter switches, so as to realize the rapid matching of the antenna matching network to different frequencies. 本发明是有关于种中波天线调配网络的频率切换方法，是针对不同频率所需要的不同的天线调配网络，通过开关切换的形式对天线调配网络的电容和电感参数进行调整，从而达到天线调配网络快速
