A Cmos Integrated Broadband Absorptive Microwave Multiplier
Tech ID: 20866 / UC Case 2008-105-0
A broadband absorptive multiplier as used in CMOS technologies is presented here and relates to microwave multipliers or mixers in general and in particular to absorptive switch networks for use in integrated wireless systems with very high bandwidth.
During the first part of the last decade several new bands were opened worldwide for ultra-wideband applications including data communications and automotive radars both of which have need for a fast switching circuit for high frequency pulse generation. In the past this was addressed by methods and devices that resulted in larger size, higher cost and greater power consumption.
Researchers at UCI have developed a CMOS integrated broadband absorptive microwave amplifier that 1) uses no inductors thus leaving a small footprint 2) consumes zero dc power and 3) operates from dc to an upper cut-off frequency.
The wide bandwidth achieved by this circuit makes it especially suitable for use in broadband wireless systems such as 3.1-10.6 GHz and 57-64 GHz ultra-wideband (UWB) communication systems and 22-29 GHZ and 77-81 GHz UWB automotive radar sensor systems.
