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.

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: An electrode structure of a resonator and a fabrication method for the electrode structure of the resonator are provided. The electrode structure includes a piezoelectric layer. An electrode metal layer, a dielectric layer, a protrusion/frame metal layer and an etching passivation layer are sequentially arranged above the piezoelectric layer. An air gap is formed between the dielectric layer and the protrusion/frame metal layer, and the air gap is located at an electrode edge. Through the air gap between the dielectric layer and the protrusion/frame metal layer above the piezoelectric layer, an electrode protrusion/frame structure of the resonator with an edge air gap is formed, which serves as an electrode part. When the resonator is working, through the air gap, a transverse sound wave can be reflected back to the resonator and be bound in a resonator body. This greatly increases the Q factor and working performance of the resonator.

Abstract: The present disclosure discloses a gesture control and interaction technology based on “touch-sensitive surface to display”. A novel interaction method is proposed by combining the touch-sensitive surface technology with display technology. Firstly, a certain gesture is made on a touch-sensitive surface to activate a certain window of the display; the sliding of the finger on the touch-sensitive surface is synchronized in GUI of the display window by the sliding operation of the finger on the touch-sensitive surface, the finger being raised, corresponds to some kind of operation; wherein, the size of the display window is variable, and the sliding of the pointer or the movement of the selection box in the window is synchronized with the sliding of the finger on the touch-sensitive surface, and the actual distance sliding on the touch-sensitive surface is scaled proportional to the movement distance of the pointer or the selection box in the window.
