A SYSTEM AND METHOD FOR PERFORMING RF FILTERING |
摘要 |
<p>A method of filtering and a RF filtering circuit comprising a LO adapted to generate in-phase and quadrature LO baseband signals; a quadrature passive mixer operatively connected to the LO; a filtering impedance operatively connected to the quadrature passive mixer, wherein the voltage at an input node of the quadrature passive mixer comprises the voltage across the filtering impedance up-converted to a frequency of a LO baseband signal received by the quadrature passive mixer. Preferably, the voltage across the filtering impedance comprises a frequency of an input signal of the quadrature passive mixer down-converted by a frequency of the in-phase and quadrature LO baseband signals and filtered by the filtering impedance.</p> |
