摘要：

This paper presents an up-conversion mixer for 2.4GHz wireless sensor networks in 0.18μm 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 0.18μm RF CMOS process.And the mixer test results indicate that under 1.8V power supply,with input frequency 2.4-2.4835GHz,the conversion voltage gain is 1.2-2dB.When the output frequency is 2.4GHz,its power gain is-4.46dB,and its input referred 1 dB compression point is-11.5dBm and it consumes 1.77mA current.
