Abstract• A 6-10 GHz broadband down conversion mixer
for UWB radio is presented.
• The broadband mixer only needs a low LO power of -3 dBm which can reduce the effect of LO leakage and DC offset.
• The broadband mixer exhibits a maximum conversion gain of 0.8 dB, and a DC power consumption of 15.75 mW at =1.5V.DDV

Introduction
• DS-UWB technology can be applied to three frequency band (3.1-5.15 GHz, 5.8-10.6 GHz, and both of them).
• The LO frequency is chosen at 8 GHz and the mixer directly down converts the 6-10 GHz RF signal into the 0-2 GHz IF frequency band.
