Fujitsu Media Devices Ltd has announced that it has developed a SAW filter that is 43 percent smaller than previous products and is targeted for use in cellphones and other portable electronic devices.

The device uses a new resin mold instead of a ceramic package to achieve miniaturization. The new resin is also claimed by the company to have solved the problem of exploding when it absorbs moisture or when it is manufactured at a high temperature.

A single-type filter measures 2-by-1.6-by-0.6mm, while a dual-type measures 2.5-by-2-by-1.6mm. Both are 1/3 the weight of conventional products and are claimed to maintain their performance for >96h of operation.
