Kyoto, Japan — Kyocera Corporation has announced that it has successfully developed two types of compact Surface Acoustic Wave (SAW) filters — for reception and transmission — that dramatically improve the prevention of radio wave interference in next-generation high-speed wireless communication networks such as WiMAX. This company claims that 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. Samples are currently available.
SAW filters are used to separate desired signals in high-frequency bands, and 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 ensure 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.
Using circuit design, simulation, and microfabrication technologies that have been developed through years of research, Kyocera has achieved a 30 dB typical attenuation of signals adjacent to 5 MHz-wide bands in the 2.6 GHz range, boasting an insertion loss of only 2.5 dB typical This claims to be an industry-first in the development of compact, revolutionary SAW filters for the prevention of radio wave interference.
As high-speed mobile wireless communication networks including WiMAX, Wi-Fi and XG-PHS are expected to show further growth, the demand for SAW filters is also expected to expand due to their effective application in high-speed mobile wireless communication networks and related devices, and wireless measuring instruments such as testers for wireless communications devices.
