Ultra Compact SAW Filters - Chip Size SAW Devices - for Mobile Communications Systems Are Now Available; World's Smallest With Ultra-Thin 0.5mm Max. Height.YOKOHAMA Yokohama (yō'kōhä`mä), city (1990 pop. 3,220,331), capital of Kanagawa prefecture, SE Honshu, Japan, on the western shore of Tokyo Bay. -- In collaboration Working together on a project. See collaborative software. with Fujitsu (company) Fujitsu - A Japanese elecronics corporation. Fujitsu owns ICL, Amdahl Corporation, and DMR. Home USA, Japan. Laboratories, Fujitsu Media Devices has developed a range of ultra-compact and ultra-thin SAW filters. Sales of the new filters will commence worldwide on May 10. The filters enable the development of smaller, slimmer, and more advanced mobile phones and other mobile communication devices.
A[micro] Main Features
A[micro] 1. Ultra-Compact, Slim-Profile
A[micro] -- Single Filter: 1.4mm typ. x 1.0mm typ. x 0.5mm max. (Volume
only 37% of previous model)
A[micro] -- Dual Filter: 1.8mm typ. x 1.4mm typ. x 0.5mm max. (Volume
only 42% of previous model)
2.0mm typ. x 1.6mm typ. x 0.5mm max. (Volume
only 53% of previous model)
A[micro] 2. Metal Sealing Delivers High Reliability
A[micro] High reliability at this small size is achieved through the
use of a special mounting structure developed by Fujitsu which
uses a hermetic structure with metal sealing. Not only is this
technique able to withstand re-flow soldering using lead-free
(high-temperature) solder, it also has excellent performance
with respect to mechanical vibration and shock.
A[micro] 3. High Performance Including Low Losses
A[micro] Insertion loss: 1.4 dB typ.
A[micro] Loss in transmission band: 18dB typ.
A[micro] 4. Extensive Product Range
A[micro] Standard models are available for all major mobile
communication systems.
A[micro] -- Single Filter: GSM850, EGSM, DCS, PCS, W-CDMA, GPS
A[micro] -- Dual Filter: GSM850+EGSM, DCS+PCS

Company Information Fujitsu Media Devices Ltd. was established in October 1998 through the merger of the Media Devices department of Fujitsu Ltd. with Fujitsu Towa Electron Ltd. By utilizing our unique high-density processing, high-frequency, and other technologies, and by taking advantage of the properties and capabilities of piezoelectric The property of certain crystals that causes them to produce voltage when a mechanical pressure is applied to them such as sound vibrations. This technique is used to build crystal microphones, phonograph cartridges and strain gauges, all of which turn mechanical movement into voltage. single crystals, we have established ourselves as a leading supplier of voltage-controlled oscillators A voltage-controlled oscillator or VCO is an electronic oscillator designed to be controlled in oscillation frequency by a voltage input. The frequency of oscillation is varied by the applied DC voltage, while modulating signals may also be fed into the VCO to cause and SAW filters and SAW duplexers for mobile communication devices. We also offer small-size modules that comply with the W-LAN W-LAN Wireless Local Area Network (also abbreviated as WLAN) and Bluetooth international standards. We are also working to develop new fields by focusing on various sensors
