Samsung Electro-Mechanics
Localizes Duplexer of WCDMA Phone
Poised to preoccupy the WCDMA phone parts market

Samsung Electro-Mechanics has announced the development of the advanced version of SAW (Surface Acoustic Wave)-Duplexer, an essential part of wideband CDMA, a third-generation mobile communications technology platform.
The company has succeeded in localizing the duplexer, a key part of CDMA phones segregating the sending and receiving frequencies without interfering with each other, company officials said. Samsung Electro-Mechanics?upgraded version of SAW-Duplexer can replace FBAR, produced by an American company, which has dominated the duplexer of the WCDMA phone. So far SAW-Duplexer cannot be adopted due to characteristics inferior to FBAR. Samsung Electro-Mechanics' advanced version of SAW-Duplexer has the same size. 3.8 x3.8mm and same Pin structure as FBAR to replace the latter without any design change.
Samsung Electro-Mechanics' advanced version of SAW-Duplexer has a competitive edge in terms of prices and delivery compared to FBAR's because the company churns out its updated version out of the existing CDMA duplexer assembly line without making further facility investments. Samsung Electro-Mechanics plans to mass-produce the updated SAW-Duplexer version from next month under a strategy of preoccupying the emerging global WCDMA parts market by making a foray into domestic and overseas major WCDMA phone manufacturing markets. The company is also seeking to develop a next-generation, 3.0x2.5mm version. The size of the global WCDMA duplexer market is projected to grow from 38 million units in 2005 to 90 million units in 2007. Mobile handset and parts makers are competing for occupying the next-generation WCDMA market.

World's first auto camera drive

Samsung Electro-Mechanics (SEM) has completed development of a unique device that rotates the camera on a mobile phone with the push of a button, and the company is now ready to carve out a new market niche. Users of conventional camera phones have to manually rotate the camera in order to change the screen from landscape to portrait. However, SEM's new auto camera drive (ACD) can do the job automatically, adjusting the camera as needed to suit a given photo subject.
The rotation takes only half a second, so there is virtually no wait, and the ACD is built to last to 70,000 cycles. That means that the driver on a phone that takes pictures 20 times a day would last more than ten years. Most mobile phones are replaced in five years, which means this component will outlive the product it is in.
Moreover, the ACD operates on just 60mA, which is at least 40% less power than that consumed by vibration motors. Moreover, it is quiet enough to be used in a library, furthering its marketability. The ACD can also be designed as a single unit with the camera module or a separate unit, depending on the mobile phone design such as the bar, folder and slide form factor.
The first consideration in the camera phone market has been resolution. Once all camera modules offer the same picture quality, the ACD can offer an additional incentive for purchasing a given model.
A survey of more than 500 mobile phone users revealed that the ACD is a value added function that consumers place at the top of their preference list. Samsung Electro-Mechanics is applying its world-leading precision motor technology to develop micro-geared motors and tiny high-precision mechanisms to develop products that satisfy consumer needs.
SEM will engage in an aggressive marketing campaign for its new ACD. At the same time, the company continues to acquire new technologies that enhance mounting reliability and change contact point structures between brush and commuter radial to extend product life and make the device even smaller. Samsung has already completed a model measuring 8.3 x L11 and is in the process of developing a micro BLDC motor, proving greater leverage in the marketplace.
Samsung Electro-Mechanics now has devices for automatically opening and closing various mobile phone types. The company already introduced an auto folder module (AFM) and has completed an auto slide unit (ASU).
SEM will continue to leverage its technologies governing micro-geared motors and precision mechanisms to expand the application of its devices to other IT products as well as a variety of appliances and robotics. nw
