Abstract
A tunable filter with wide tuning range and high out-of-band rejection is achieved with a tunable bandpass filter and a number of cascaded, fixed frequency Lame-Mode Resonators (LMRs) notch filters or other resonators. In some embodiments, the filter can be implemented with all of the elements on an integrated circuit, saving space for use in applications such as mobile phones or other mobile communication devices.
