RF Double Balanced Current Mirror UP-Conversion Mixer at 2.4 GHz Frequency

Abstract

A 2.4 GHz CMOS based highly linear; low power, low voltage with minimum noise figure current mirror UP conversion mixer in 0.18 micrometer technology is designed. The proposed UP conversion mixer is based on current mirror technology and class AB topology of the power amplifier. In addition to it by using previous current mirror technology and class AB topology in mixer image rejection of the mixer is improved, nonlinearity of the mixer decreases and further more power dissipation of mixer is also reduced. The implemented UP conversion mixer has conversion gain of 6.89 dB with third order intercept point (IIP3) −3.05 dBm and Noise Figure of the Mixer is 10.6 dB with supply voltage of 1.8 V and operating frequency is 2.4GHz.
