  • Publication number: 20160294422
    Abstract: A system includes a first filter circuitry and one or more second filter circuitry. The first filter circuitry can operate at a frequency of a wireless signal to filter the wireless signal to attenuate undesired feedthrough components and pass through a desired component. The system can also include a multi-phase mixer to convert the frequency of the wireless signal to a lower frequency and divide the wireless signal into at least four phase shifted baseband signal components. The second filter circuitry can operate at the lower frequency to filter the phase shifted baseband signal components to attenuate undesired feedthrough components and pass through a desired component. The system can also include a matrix to combine the baseband signal components to form an output signal.
