Abstract

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 3G 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: 3^rd order input intercept point=14.466 dBm ges 11 dBm, noise figure=9 dB and conversion loss=11 dB.
