A dielectric filter with a first radio frequency (RF) passband and a second RF passband, a radio unit, an antenna unit and a base station are disclosed. According to an embodiment, the dielectric filter () comprises a body () with a plurality of resonators () including a first resonator (), a second resonator () and a common resonator (). The common resonator () is coupled under its first resonance mode to the first resonator () to provide the first RF passband, and is coupled under its second resonance mode to the second resonator () to provide the second RF passband.

Dielectric filter, and AU, RU or BS having the same

An antenna unit, a radio unit, and a base station are disclosed. The antenna unit or the radio unit includes a plurality of filters, each having a respective radio frequency passband. At least one first filter is a CWG filter. The first filter is coupled to a second filter through a T-junction formed on an antenna board or a radio mother board.
