Zusammenfassung: | The embodiment of the invention discloses a hybrid filtering device and hybrid filtering equipment. The hybrid filtering device comprises at least one high-pass filtering module and at least one acoustic resonance module, all the high-pass filtering modules are sequentially connected in series to form a series main circuit, and the two ends of each acoustic resonance module are connected with the two ends of the corresponding high-pass filtering module, so that all the acoustic resonance modules are connected to all the high-pass filtering modules in parallel; and each acoustic resonance module forms a parallel branch. The high-pass filtering module has the characteristic of high bandwidth, can transmit broadband high-frequency passband signals, and can effectively filter low-frequency stopband signals. The acoustic resonance module can attenuate the stop-band signal and reduce the influence of the stop-band signal on the pass-band signal, so that the attenuation of the hybrid filtering device on the stop-ban |
