摘要：

This paper presents an up-conversion mixer for 2.4 GHz wireless sensor networks in 0.18 μm RF complementary metal-oxide semiconductor (CMOS) technology. It is based on a double-balanced Gilbert cell type. With two Gilbert cells it was applied quadrature modulation. Operational amplifiers are used in this design to improve the conversion gain under low power consumption. The mixer design is based on 0.18 μm RF CMOS process. And the mixer test results indicate that under 1.8 V power supply, with input frequency 2.4-2.4835 GHz, the conversion voltage gain is 1.2-2 dB. When the output frequency is 2.4 GHz, its power gain is -4.46 dB, and its input referred 1 dB compression point is -11.5 dBm and it consumes 1.77 mA current.
