Abstract :
A CDMA-2000 receiver that eliminates the interstage SAW filter is presented. An active technique is proposed for filtering the transmitter leakage after downconversion. This technique improves the triple-beat (TB) and IIP2 performances by 6.5 dB each, at the expense of a small increase in DC current and noise.
