This paper reports a high IIP3 even harmonic mixer with a new circuit configuration. This mixer employs an antiparallel diode pair, open and short circuited stubs and a radial stub as filters to separate RF input signal, Baseband output signal and LO Power. This mixer is used for down converting 3 G Mobile downlink Signal at 2140 MHz to BaseBand by using a local oscillator at 1070 MHz in direct conversion configuration. This mixer must comply with the requirements specified by 3G UMTS: 3rd
