Abstract (en)
[origin: EP3217468A1] Embodiments of the present invention provide a transverse electromagnetic mode dielectric filter. A near-end rejection structure is disposed inside the filter. By flexibly designing a shape, a location, and a size of the near-end rejection structure, a transmission zero or zero cavity function is implemented, and a radio frequency signal on a high-frequency end or a low-frequency end out of a passband of the filter is rejected, thereby achieving good near-end rejection performance. The embodiments of the present invention further provide a radio frequency module and a base station.
