Patent ID: 8588723

Claim:
A general receiver device with adaptive filter, comprising: an antenna for receiving a radio frequency signal with a plurality of bands, each band having a plurality of channels; a low noise amplifier connected to the antenna for amplifying the radio frequency signal so as to generate an amplified radio frequency signal; a bandpass tracking filter connected to the low noise amplifier for filtering the amplified radio frequency signal so as to generate a filtered radio frequency signal; a single-ended-to-differential converter unit connected to the bandpass tracking filter for converting the filtered radio frequency signal into a differential radio frequency signal; a mixer connected to the single-ended-to-differential converter unit for receiving a differential local oscillation signal so as to generate a differential intermediate frequency signal; an adaptive filter connected to the mixer for filtering the differential intermediate frequency signal so as to generate a filtered differential intermediate frequency signal; and a filtered intermediate frequency automatic gain control amplifier connected to the adaptive filter for amplifying the filtered differential intermediate frequency signal so as to generate an amplified differential intermediate frequency signal.
