A Low-Voltage 5-GHz Quadrature Up-Conversion Mixer for Wireless Transmitter

摘要：

In this paper, a low-voltage CMOS quadrature up-conversion mixer for 5-GHz wireless communication applications is designed. The simulation results demonstrate the mixer can reach a high conversion gain (CG), a low noise figure (NF), and a high linearity (IIP3). A miniature lumpedelement microwave broadband rat-race hybrid and RLC shift network are used for the LO and the IF port design, respectively. The mixer exhibits a 3dB improvement in noise and conversion gain, and the image rejection is -35dBc. The mixer achieves noise figure of 12.8 dB, a conversion gain of 15 dB, an output third intercept point at 0dBm, while dissipating 15mW for operating voltage at 1 V. The mixer is designed with TSMC 0.18 um process.
