Avago Technologies Announces FBAR Filter Design Wins

Avago Technologies, a provider of analog interface components for wireless, wireline and industrial applications, recently obtained design wins for numerous products based on their Film Bulk Acoustic Resonator (FBAR) filter technology.

These designs from Avago support operations in 15 frequency bands.

A thin-film bulk acoustic resonator (FBAR) is a device that includes a piezoelectric material put in between two electrodes. FBAR devices make use of piezoelectric films with thicknesses ranging from numerous micrometers, down to a tenth of micrometers resonate in the frequency range of roughly 100 MHz to 10 GHz.

FBAR filtering has the capacity to improve smartphone operations. To enable functioning on even the highest frequency (closest) Wi-Fi channels without interference, the Avago ACMD-6107 duplexer offers ample safety. 

Mostly rendering the upper Wi-Fi channels unusable, other filters do not offer the needed out-of-band attenuation as effectively, the company has stated.

“FBAR technology has gone mainstream. Three years ago, when most applications were 3G based, only 4-5 different bands benefited from using FBAR filtering," said Bryan Ingram, senior vice president and general manager of Avago Wireless Semiconductor Division. "Now, as worldwide carriers move to 4G/LTE (News - Alert), filter specifications are much more stringent, and in many cases FBAR filters are the best solution to meet the requirements.”

“To fulfill this demand, Avago now supports as many as 15 different frequency bands with FBAR products.”

Recently, the company was selected as Supplier of the Year for 2012 by Brocade (News - Alert). Avago stated that the company was happy to be recognized for its efforts in supplying innovative fiber optic products to Brocade. These products from the company support their Fiber Channel and Ethernet networking solutions.

The company was looking forward to a continuing working relationship with Brocade.
