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.

Abstract: A receiver includes at least one receive channel. The at least one receive channel includes a first receive channel, and the first receive channel includes a first inductor and a first receiving circuit that are coupled to each other. The first inductor is configured to filter a received signal of a first frequency band to obtain a first received signal. A self-resonant frequency of the first inductor is in an interference frequency band corresponding to the first frequency band. The first receiving circuit is configured to process the first received signal.
