Kyocera has developed two types of compact Surface Acoustic Wave (SAW) filters SF3030B2G600T10MAL0 for reception and SF2525E2G620T10MAH0 for transmission that dramatically improve the prevention of radio wave interference in next-generation high-speed wireless communication networks such as WiMAX.
This development creates 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 of the new SAW filters are currently available.
SAW filters are used to separate desired signals in high-frequency bands. 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.
Using circuit design, simulation, and microfabrication technologies that have been developed through years of research, Kyocera has achieved a 30 dB typ. attenuation of signals adjacent to 5 MHz-wide bands in the 2.6 GHz range, boasting an insertion loss of only 2.5 dB typ. This is 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.
