Abstract
The present disclosure is related to an antenna filter unit (AFU), a radio unit (RU), and a communication device including the same. The AFU includes: one or more antenna elements; a first digital phase shifter communicatively coupled to at least a first antenna element of the one or more antenna elements, and configured to shift a phase of a first signal that is to be transmitted by the first antenna element; and a first IM filtering module communicatively coupled between the first digital phase shifter and the first antenna element, and configured to filter out an IM component from the first signal and output the filtered first signal.
Claims22
An antenna filter unit (AFU), comprising:
- one or more antenna elements;
- a first digital phase shifter communicatively coupled to at least a first antenna element of the one or more antenna elements, and configured to shift a phase of a first signal that is to be transmitted by the first antenna element;
- and
- a first intermodulation (IM) filtering module communicatively coupled between the first digital phase shifter and the first antenna element, and configured to filter out an IM component from the first signal and output the filtered first signal.
