Abstract: Certain aspects of the present disclosure provide an N-path filter implemented using a generalized impedance converter (GIC) circuit. The GIC circuit is configured such that the N-path filter has a desired frequency response, which may include a wide passband with steeper rejection than a conventional N-path filter with only a single pole in each filter path. Certain aspects of the present disclosure provide an N-path filter having a frequency response with multiple concurrent passbands. In certain aspects, the N-path filter with multiple passbands is implemented using the GIC circuit. In other aspects, the N-path filter may include a bandpass response circuit where an inductance of the bandpass response circuit may be implemented using gyrators.

Abstract: Methods and apparatuses are presented for harmonic reject upconverting a baseband signal using at least one quadrature passive upconversion mixer. In some embodiments, an apparatus may include a first quadrature passive mixer configured to receive a first baseband input and a first LO input, and a second quadrature passive mixer configured to receive a second baseband input and a second LO input. A first output of said first passive mixer may be directly connected to a first output of said second passive mixer and together coupled to a first amplifier input. A second output of said first passive mixer may be directly connected to a second output of said second passive mixer and together coupled to a second amplifier input. The transmitter may be configured to output an upconverted signal with at least one rejected harmonic spurious mixing product based on the first and second amplifier inputs.
