Fujitsu Media Devices Developed Ultra-compact SAW Duplexers and Filters for W-CDMA
- Using Hermetic Seals to Create the World's Smallest Device -
Fujitsu Media Devices has developed the world's smallest SAW duplexers (for bands I, II, IV, V and VIII) for W-CDMA mobile phones and SAW filters for GSM (850, 900, 1800 and 1900) technology, using a hermetic seal structure. Samples will be available beginning in July. We expect to begin mass-production in the first quarter of FY2009. Use of these devices will contribute to the production of smaller and more advanced mobile phones that can be used worldwide.

Fujitsu Media Devices has once again taken the lead in contributing to space-saving within mobile phones for RF components by using a hermetic seal structure to develop the world's smallest W-CDMA SAW duplexers and GSM SAW filters. The SAW duplexers are 2.0×1.6 mm (with a maximum height of 0.5 mm) and 2.5×2.0 mm (with a maximum height of 0.6 mm). Single SAW filters (for GSM 850 and 900) are 1.1×0.9 mm (with a maximum height of 0.5 mm) and dual filters (for GSM 850 and 900, or 1800 and 1900) are 1.5×1.1 mm (with a maximum height of 0.5 mm).
Product Characteristics
- The use of a hermetic seal structure has realized the world's smallest size while maintaining MSL1.(1)
| SAW duplexers | bands I, II, IV and VIII 2.5×2.0 mm (maximum 0.6 mm height) band V 2.0×1.6 mm (maximum 0.5 mm height) |
|
| SAW filters | GSM 850 and 900 1.1×0.9 mm (maximum 0.5 mm height) GSM 850, 900, dual 1.5×1.1 mm (maximum 0.5 mm height) GSM 1800, 1900, dual 1.5×1.1 mm (maximum 0.5 mm height) |
- Compatible with interfaces for the currently predominant transceiver ICs.
The SAW duplexers use a 50 ohm unbalanced interface for the antenna and transmitter pins and a 100 ohm balanced interface for the receiver pins.
The SAW filter’s input interface is 50 ohm, unbalanced, and the output interface is 150 ohm, balanced.
Sample Pricing
| Product | Sample Price | Shipment Dates |
|---|---|---|
| SAW Filters | US$ 5.00 | starting July 7, 2008 |
| SAW Duplexers | US$ 10.00 | starting July 7, 2008 |
Sales Plan
Beginning in the first quarter of FY2009, our plans are to produce ten million duplexers and twenty million filters per month.
Trends in the W-CDMA Mobile Phones Market
Research indicates that demand for mobile phones in 2008 will approach 1.3 billion units(2), of which 230 million units(2) are expected to be W-CDMA compatible, nearly all of which will include GSM functionality.
Notes
(1) MSL stands for Moisture Sensitivity Levels and is based on the resistance of semi-conductor packages to humidity and moisture absorbency. A rating of 1 indicates that re-flow soldering can be done without any dry process.
