Reconfigurable RF filter
First Claim
1. A reconfigurable RF filter, which comprises a first resonator, a second resonator, and a first coupling circuit, which is coupled between the first resonator and the second resonator;
- wherein;
the reconfigurable RF filter is configured to operate in one of a plurality of operating modes, such that the plurality of operating modes comprises a first operating mode and a second operating mode;
during the first operating mode, the reconfigurable RF filter is a bandpass filter having a first bandwidth and a first insertion loss through the first resonator, the first coupling circuit, and the second resonator; and
during the second operating mode, the reconfigurable RF filter is a bandpass filter having a second bandwidth and a second insertion loss through the first resonator, the first coupling circuit, and the second resonator, such that the first bandwidth is greater than the second bandwidth and the first insertion loss is less than the second insertion loss.

Abstract
A reconfigurable RF filter, which includes a first resonator, a second resonator, and a first coupling circuit, is disclosed. The first coupling circuit is coupled between the first resonator and the second resonator. The reconfigurable RF filter operates in one of a group of operating modes, which include a first operating mode and a second operating mode. During the first operating mode, the reconfigurable RF filter is a bandpass filter having a first bandwidth and a first insertion loss via the first resonator. During the second operating mode, the reconfigurable RF filter is a bandpass filter having a second bandwidth and a second insertion loss via the first resonator, such that the first bandwidth is greater than the second bandwidth and the first insertion loss is less than the second insertion loss.
