Academics crank on 60 GHz

Clearly 60 GHz design has hit the radar screen. Three leading research organizations came to ISSCC talking about 60 GHz advances.

The most significant move came from Belgium’s IMEC which described a digital CMOS receiver antenna to limit high-path signal loss. The dual-antenna device uses a programmable phase shift and integrates a low-noise amp and down converter. IMEC’s next step is to use 45nm technology to craft a four-antenna device that integrates a phase-lock loop and ADC.

IMEC is inviting the industry to join its research efforts. Back in the U.S., Berkeley’s labs have already spawned what appears to be the early leader in the field, SiBeam. But the startup’s initial products are aimed at wired-only systems.

Graduate students from Berkeley and UCLA came to ISSCC showing low-power 60 GHz receivers dissipating as little as 24 mW and thus suitable for battery-driven devices. But the 60 GHz transmitters eat perhaps twice as much power, and both researchers are still in early stages of designing full transceiver to bring 60 GHz to mobile systems.

Did you heard about the 60GHz antenna developed at the Polygram research center from University of Montreal (QC):

What do you think of it?

This goes to show how broad academic work is in this area now, but the link does not provide much detail. If you'd like todescribe the specifics of your work, others here may be interested.

In the February IEEE Spectrum magazine on page 46-, Behzad Razavi (UCLA) wrote an article on "Gadgets Gab at 60 GHz". One of the themes of the article is how silicon is attempting to challenge GaAs for 60 GHz.

hey....can u provide some links to ongoing research on protocol level in 60 ghz networks

I'd start with the Berkeley wireless group that has done a lot of pioneering work here under Bob Broderson, also an exec with 60 GHz startup SiBeam .

See http://bwrc.eecs.berkeley.edu/

I would also troll the ISSCC 2008 wireless sessions. There was at least one or two other universities doing some leading edge grad work in the area.

And if anyone knows of other 60 GHz startups, I'd like to hear about them.
