  • Receiver and Receiving Method of Receiver
    Publication number: 20140080433
    Abstract: Embodiments of the present invention provide a receiver and a receiving method of the receiver, so that monolithic integration of multiple receiving channels can be implemented. The receiver includes: a zero intermediate frequency channel, performing in-phase/quadrature (IQ) down conversion on a radio frequency signal at a first frequency band using a frequency division or frequency multiplication signal of a first oscillation signal; and a superheterodyne channel, performing down conversion on a radio frequency signal at a second frequency band using the frequency division or frequency multiplication signal of the first oscillation signal, where the first frequency band is different from the second frequency band.

  • Equivalent radio frequency notch filter, radio frequency chip, and receiver
    Patent number: 8385873
    Abstract: An equivalent radio frequency (RF) notch filter, an RF chip, and a receiver are provided. The equivalent RF notch filter includes: a local oscillation (LO) circuit, configured to provide a LO frequency signal; configured to be connected in parallel with the main chain, and down-convert signals of the main chain; and a frequency selective circuit realized by impedance difference, configured to provide different impedances for down-converted signals with different frequencies from the mixing circuit, so as to absorb the signals that need to be suppressed.
