Mobile communication device

摘要

Embodiments provide a mobile communication device comprising an adaptive filter for filtering a RF signal and a controller. The adaptive filter comprises a first terminal, a second terminal, a reference terminal for providing a reference potential, a first filter structure connected in series between the first terminal and the second terminal, a second filter structure connected in series between the first terminal and the reference terminal, and a third filter structure connected in series between the second terminal and the reference terminal, wherein at least one filter structure of the first, second and third filter structures comprises at least one switchable filter element. The controller is configured to selectively activate or deactivate the at least one switchable filter element based on the RF signal or a baseband version thereof.

1. A mobile communication device, comprising:
an adaptive filter configured to filter an RF signal, wherein the adaptive filter comprises a first terminal, a second terminal, a reference terminal for providing a reference potential, a first filter structure connected in series between the first terminal and the second terminal, a second filter structure connected in series between the first terminal and the reference terminal, and a third filter structure connected in series between the second terminal and the reference terminal, wherein at least one of the first, second and third filter structures comprises at least one switchable filter element; and a controller configured to selectively activate or deactivate the at least one switchable filter element based on the RF signal or a baseband version thereof in order to shift a notch of a second harmonic in its frequency such that a frequency at which a suppression of harmonics comprises its maximum value is selectable.
