    Abstract: A power supply circuit for an LED color-changing lamp is provided, which includes an input rectification circuit, an input filtering circuit, a control circuit, a transformer T1, an output rectification circuit, and an output filtering circuit; an input terminal of the input rectification circuit is connected to an AC power, an output terminal of the input rectification circuit is connected to the input filtering circuit. The input filtering circuit and the control circuit are both connected to an original side of the transformer T1; the output rectification circuit and the output filtering circuit are both connected to a secondary side of the transformer T1. The control circuit includes a first chip U1 in a model of MT3612. Through the above arrangement, the circuit is more integrated, the number of components in the circuit is reduced, the circuit structure is simplified, and the volume of the circuit board is reduced.

    Abstract: A surface wave device filter comprises two 2-pole waveguide coupled double mode resonators (WCRs) electrically connected together in cascade. To permit narrowing of the filter passband for improved out-of-band rejection, e.g. for use of the filter as an intermediate frequency channel filter in a wireless communications system, while maintaining good matching for low ripple in the passband, a shunt capacitance is connected in parallel with the static capacitances of the two WCRs. The shunt capacitance is constituted by interdigital fingers provided on the same piezoelectric substrate as one or both of the WCRs, perpendicularly to the WCR fingers to avoid surface wave interference, conveniently in space otherwise used by rails of the WCRs, optionally with oppositely phased fingers to cancel surface waves generated by these fingers. A capacitance can be similarly provided on the same substrate as any other type of surface wave device.
