Abstract
A filter module includes filters. Each of the filters is configured to control communications bands having overlapping bandwidths each with the other. Each of the communications bands, allocated to any one of the filters, has a different limit frequency from the other.
Claims15
A filter module, comprising:
- filters, each having an allocated frequency band, among frequency bands, and each being configured to control communications bands included in the allocated frequency band having overlapping bandwidths with each other,
- wherein each of the communications bands included in the allocated frequency band of one or more of the filters has a different limit frequency from others of the communication bands included in the allocated frequency band of the one or more of the filters, and
- wherein the one or more of the filters is configured to change one of an upper limit frequency and a lower limit frequency of the allocated frequency band of the one or more of the filters such that overlapping of the bandwidths is maintained.
A front end module, comprising:
- an antenna configured to transmit and receive radio frequency signals;
- and
- a filter module configured to filter components of the radio frequency signals in specific frequency bands, the filter module comprising filters each having an allocated frequency band, among the frequency bands, and each being configured to control communications bands included in the allocated frequency band having overlapping bandwidths with each other,
- wherein each of the communications bands included in the allocated frequency band of one or more of the filters has a different limit frequency from others of the communications bands included in the allocated frequency band of the one or more of the filters, and
- wherein the one or more of the filters is configured to change one of an upper limit frequency and a lower limit frequency of the allocated frequency band of the one or more of the filters such that overlapping of the bandwidths is maintained.
