APPARATUS FOR IMPROVING CROSS MODULATION CHARACTERISTIC OF CDMA PORTABLE WIRELESS TERMINAL

摘要

PURPOSE: An apparatus for improving the cross modulation characteristic of a CDMA(Code Division Multiple Access) portable wireless terminal is provided to resolve a degradation program of a receiving performance by an inter modulation of a receiving signal. CONSTITUTION: A filter(221) passes a signal except for an IF(Intermediate Frequency) band. An IF amplifier(222) amplifies the signal through the filter(221). An integrator(223) converts the signal through the IF amplifier(222) into a DC signal. The first comparator(224) and the second comparator(225) compare signals output from the integrator(223). A synthesizer(226) synthesizes outputs of the first comparator(224) and the second comparator(225).
