摘要

基于2.4 GHz的高线性CMOS;设计了低功耗、低电压、噪声系数最小的0.18微米工艺电流镜UP转换混频器。所提出的UP转换混频器基于电流镜像技术和功率放大器的AB类拓扑结构。除了利用以往的电流镜像技术和混频器中的AB类拓扑结构，改进了混频器的消像性能，降低了混频器的非线性，进一步降低了混频器的功耗。所实现的UP转换混频器的转换增益为6.89 dB，三阶截距点(IIP3)为−3.05 dBm;混频器的噪声系数为10.6 dB，电源电压为1.8 V，工作频率为2.4GHz。

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

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.
