IP2 METHOD AND APPARATUS FOR SECOND ORDER INTERCEPT POINT IP2 CALIBRATION

摘要

An apparatus and method for IP2 calibration are provided. The apparatus for IP2 calibration includes a processor that generates a first square wave in the radio frequency integrated circuit and a second square wave in the baseband integrated circuit, Transforming the modulated radio frequency waveform to an intermediate frequency, filtering the down-converted radio frequency waveform, converting the filtered radio frequency waveform into a digital signal, And the first square wave and the second square wave are driven by a reference frequency oscillator.
