Abstract :
A 3-5 GHz UWB BiFET mixer is designed using standard Jazz 0.35mum SiGe BiCMOS process. The presented BiFET mixer using BJT as the transconductor stage and MOSFET as the switch stage to achieve better noise and linearity trade off while consume a very low current. The measured results of this direct conversion broadband mixer shows a maximum conversion power gain of 5.1dB at 3GHz, with IF frequency of 10MHz. The mixer core operates from a supply voltage of 3 V and draws a total current of 2.5mA
