<p>A high frequency filter, including at least one coaxial resonance cavity. At least one printed circuit board is provided outside the coaxial resonance cavity. One surface of the printed circuit board is provided with a metal conductor layer for performing signal connection on a source and a load, and the other surface opposite to the surface provided with the metal conductor layer is provided with a grounding metal conductor layer. The consistency of the printed circuit board ensures the consistency of indices of the filter such as standing waves, phase and group delay and so on.</p> |
