Fujitsu Media Devices Developed Ultra-Compact SAW Duplexers and SAW Filters for W-CDMA
Comtex
YOKOHAMA, Japan, Jul 03, 2008 (BUSINESS WIRE) ----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.
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.
Product Characteristics 1. The use of a hermetic seal structure has realized the world's smallest size while maintaining MSL1.(1) ---------------------------------------------------------------------- bands I, II, IV and VIII 2.5 x 2.0 mm (maximum 0.6 mm SAW duplexers height) -------------------------------------------------------- band V 2.0 x 1.6 mm --------------------------------------------------- GSM 850 and 900 1.1 x 0.9 mm (maximum 0.5 mm ------------------------------------- height) SAW filters GSM 850, 900, dual 1.5 x 1.1 mm ------------------------------------- GSM 1800, 1900, dual 1.5 x 1.1 mm ----------------------------------------------------------------------
2. 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.
(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.
Sample Pricing ---------------------------------------------------------------------- Product Sample Price Shipment Dates Sales Plan (starting in 1Q of FY2009) ---------------------------------------------------------------------- SAW Filters USD 5.00 starting July 7th 20 million units/month ---------------------------------------------------------------------- SAW Duplexers USD 10.00 starting July 7th 10 million units/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.

No, it's not a dance craze. Contago is a condition of supply and demand, essentially a fancy word to say that prices for items, typically commodities, are cheaper now than they would be at some point down the line.
Anything that¿s sold in the futures market can be in a case of contango. Futures are exactly that: a contract to buy an item or asset at a price in the future. This is the case with oil, with traders buying and selling contracts to acquire a barrel of oil in months down the line. When a market is in contango, spot prices, or the price of a commodity if you were to buy it right now, are lower than forward prices.
Why is that important? Well, it usually tells you the supply of a given commodity is plentiful (since, according to Economics 101, a large supply usually leads to cheap prices).
Incidentally, if you think contango is a mouthful, its opposite condition is known by the equally tongue-tying term backwardation.
