mm waves in the mix

A millimetre-wave integrated mixer that uses around 75% less power than previous designs has been presented by researchers in Taiwan. The research team at National Central University used a Darlington-pair topology to reach V-band operation, and a thin-film LC-hybrid linear combiner in 90%nm CMOS to create a compact mixer chip that should be easy to produce on a large scale for future applications, such as wireless HD home networking, game consoles and car radars.
