Abstract
Description
technical field
[0001] The invention relates to the field of electronic communication, in particular to a frequency hopping filter. Background technique
[0002] The frequency hopping filter is generally installed at the output port of the power amplifier of the transmitter, which is used to effectively filter out useless transmission clutter frequencies and prevent wireless interference signals from other transmitters from entering the local transmitter. The frequency hopping filter is a bandpass filter device. The disadvantages of current high-power frequency-hopping filter design are that the insertion loss is large, the filtering effect is not good, and the heat dissipation of the components is poor, resulting in a short working life. To dissipate heat; the existing high-power frequency-hopping filter products are large in size and high in manufacturing cost. Contents of the invention
[0003] The embodiment of the present invention provides a frequency hopping filte...
