Title
(EN) Diversity amp module and apparatus comprising the same
Abstract
(EN)

An amplifying module having one input terminal and one output terminal and passing an antenna signal input through the input terminal towards the output terminal. The amplifying module includes a first switch connected to the input terminal, a plurality of filters selectable by the first switch, a plurality of amplifiers respectively connected to the plurality of filters and amplifying a signal that has passed through the filters, and a second switch for connecting the amplified signal to the output terminal.
