A 3-8 GHz broadband mixer is presented in this paper. This broadband mixer is low power and high conversion gain. It provides current reuse and ac-coupled folded switching. This mixer is designed in TSMC 0.18-mu m CMOS technology. This broadband mixer achieves simulated conversion gain of 9 +/- 1.5 dB, a single sideband noise figure lower than 15.2 dB and IIP3 batter than -7 dBm. From 3-8 GHz, at supply voltage of 1.5 V power consumption without output buffer is 3.27 mW and power consumption with buffer is about 8 mW. The chip area is 1079 mu m x 761 mu m.
