Abstract:
An RF front end arrangement comprises first filtering, second filtering, third filtering, fourth filtering and a switching arrangement. The switching arrangement is configured to selectively connect the filtering to plural antennas such that at a particular time the first and third filtering is connected to a first antenna and the second and fourth filtering is connected to a second antenna. This allows filtering with different frequency response characteristics to be in use simultaneously for the same frequency band. This can reduce the insertion loss associated with a signal path.
