Electronic components used in high-performance smartphones require further miniaturization. In particular, SAW devices with the function of transmitting and receiving specific frequencies, because they support multi-band of smart phones, even if they are used in a specific region, the average model uses 14 to 15 each, while the advanced models used in the world must use 30. ~40, it is a device that is extremely miniaturized. The company's unique design and miniaturization technology have completely improved the chip design and packaging methods, and developed ultra-small sizes with the same features as traditional products.
main feature
The features of this product are as follows.
Ultra-small SAW device
The SAW duplexer "SAYAV series", "SAYRV series", and "SAYAP series" supporting the 700MHz to 2.6GHz band are 1.6mm × 1.2mm (length × width), and the SAW filter "SAFFW series" is 0.9mm × 0.7mm (length × width), the product size is about 24% smaller than the previous product *3 (duplexer) and 37% (filter), which can greatly reduce the packaging area of electronic circuits and contribute to high-density circuit design.
*3 is compared with a 1.8mm x 1.4mm SAW duplexer and a 1.1mm x 0.9mm SAW filter.

Achieve the same or higher characteristics as traditional products
The company's unique design and miniaturization technology suppresses deterioration of characteristics due to miniaturization and achieves excellent characteristics. The transmission characteristics*4 and isolation characteristics*5 of this product are equal to or higher than those of traditional products. In addition, we are preparing for the future of high-powered smartphones such as the 5th generation mobile communication system (5G), and we have achieved improvements in power durability.
*4 Degree of loss of transmission between the antenna and the transceiver circuit.
*5 The duplexer will transmit and receive the characteristics of the respective filtering functions.
Product lineup with main support bands
This product supports the complete product lineup of the main frequency bands in the band classification specifications specified by the standard group 3GPP*6.
The main communication band from 700 MHz to 2.6 GHz is supported at the end of 2019. In addition, products supporting the 5-6 to 6 GHz sub-6 band that may be newly used by 5G will be developed. In the future, the company will develop small products according to the needs of the market and customers, and contribute to the space-saving and high-density circuit design of electronic circuits.
