  • Multipath filters
    Patent number: 10454724
    Abstract: Multipath filters are provided herein. In certain configurations, a multipath filter includes multiple filter paths or circuit branches that are electrically connected in parallel with one another between an input terminal and an output terminal. The input terminal receives an input signal, and each filter circuit branch includes a double-in double-switched (DIDS) downconverter that downconverts the input signal with two different clock signal phases to generate a downconverted signal. Each filter circuit branch further includes a filter network that generates a filtered signal by filtering the downconverted signal and an upconverter that upconverts the filtered signal to generate a branch output signal. Additionally, the branch output signals from the filter circuit branches are combined to generate an output signal at the output terminal.
