发明名称 Image Rejection Calibration With A Passive Network
摘要 In one aspect, an apparatus includes: a mixer to receive a radio frequency (RF) signal and downconvert the RF signal into a second frequency signal; an amplifier coupled to the mixer to amplify the second frequency signal; an image rejection (IR) circuit coupled to the programmable gain amplifier (PGA) to orthogonally correct a gain and a phase of the amplified second frequency signal to output a corrected amplified second frequency signal; and a complex filter to filter the corrected amplified second frequency signal.
