Saw filter operating in 2.6 GHz range with high selectivity

Kyocera is sampling two types of compact Surface Acoustic Wave (SAW) filters - for reception and transmission. These filters prevent radio wave interference in high-speed wireless communication networks such as WiMAX.

Kyocera says these are the first SAW filters in the industry in the high-frequency range of 2.6 GHz to feature high selectivity and low loss characteristics. This is an industry-first in the development of compact, revolutionary SAW filters for the prevention of radio wave interference.

SAW filters separate desired signals from RF signal. The 2.6 GHz range, which is used by diverse communications networks, is a particularly highly congested frequency. Consequently, these new compact SAW filters were developed to improve usability in order to assure stable communications through the prevention of radio wave interference with other systems in adjacent signals during data transmissions and data communications in next-generation high-speed wireless networks.

These new filter feature a 30 dB typ. attenuation of signals adjacent to 5 MHz-wide bands in the 2.6 GHz range, with an insertion loss of 2.5 dB typ.

The growing use of high-speed wireless for data connectivity enable the demand for SAW filters such as these newly released components.

Application for these filters:

Prevention of radio wave interference among signals in the giga hertz band
- Wireless communications base stations such as repeaters in the 2.4 to 2.6 GHz frequency ranges
- High-speed data communication terminals and PCs that have built-in WiMAX, Wi-Fi or
XG-PHS
- Measuring instruments such as testers for wireless communications devices
