[TVTechnology] Potential RF Filter Breakthrough Announced

The ability of receivers to reject signals outside the frequencies they are trying to receive is becoming more important. The recent LightSquared debacle was an excellent example of this. LightSquared was unable to use its mobile satellite spectrum for terrestrial broadband because GPS receivers couldn't handle the strong signals planned by LightSquared that would be close to the GPS band.

Dana Weinstein, an MIT assistant professor of electrical engineering and computer science, and Laura Popa, an MIT graduate student in physics, working with researchers at MIT's Microsystems Technology Laboratory (MTL) may have found a way to filter a wide range of frequencies in a small space. Their solution is miniature filters created using acoustic resonators. Using acoustic resonators created with techniques already common in the production of signal-processing chips, their filters improve performance while enabling 14 times as many of them to be crammed on a single chip.

Now here's some nice meaty tech news. The thing I fond most interesting is that in this very special case, mechanical technology has trumped it's electronic counterpart in the miniaturization race. This might very well be the last time we ever see that happen.

It's kind of ironic that you post this and have the Mam Head room incident as your avatar.

I think by ironic you mean "fitting."
