Abstract: The technology of this application relates to the field of filter technologies, and provides a common mode filter and a terminal device. The common mode filter includes a first winding and a second winding. A portion of the first winding and a portion of the second winding are formed, by rotating around a same axis, at a first coil layer. The other portion of the first winding and the other portion of the second winding are formed, by rotating around another same axis, at a second coil layer stacked with the first coil layer. At the first coil layer and the second coil layer, there is one turn of the second winding between each two adjacent turns of the first winding.

Abstract: The present disclosure relates to telecommunication, and in particular, to a base station Radio Frequency (RF) duplexer, an RF module, and an RF system. A base station RF apparatus provided herein includes: an enclosure, an intermediate RF processing unit, and a duplexer. The enclosure is located on the duplexer; the intermediate RF processing unit is located inside a cavity enclosed by the enclosure and the duplexer, or on the duplexer; a duplexer cavity and a heat dissipation part exist on the surface of the duplexer; the opening of the duplexer cavity is opposite to or against the enclosure; the heat dissipation part is designed to dissipate heat of the intermediate RF processing unit; and the duplexer is integrally molded. The foregoing technical solution requires no external fasteners, reduces the time of production and assembly. In addition, waterproof design and shielding design are not required, and thus improves the reliability.
