Abstract
A general receiver device with adaptive filter includes an antenna, a low noise amplifier, a bandpass tracking filter, a single-ended-to-differential converter unit, a mixer, and an adaptive filter. The antenna receives an RF signal. The low noise amplifier amplifies the RF signal for generating an amplified RF signal. The band-pass tracking filter filters the amplified RF signal for generating a filtered RF signal. The single-ended-to-differential converter unit converts the filtered RF signal into a differential RF signal. The mixer receives a differential local oscillation signal and uses the differential local oscillation signal to down-convert the differential RF signal into a differential IF signal. The adaptive filter filters the differential IF signal for generating a filtered differential IF signal.
