The EC646 from KYOCERA AVX is a Switch and Tune Chipset that operates from 100 to 3000 MHz. It allows the RF front-end to cover global bands and seamlessly improve performance in a dynamically changing RF environment by employing active tuning. The chipset provides wider global band coverage (including LTE) with a single antenna element using parasitic loading and active tuning techniques to improve RF front-end performance, especially for stringent low band (LTE) antenna efficiency requirements. It can be used in a variety of applications including wireless devices, cell phones, and M2M products.
The EC646 uses the Ether Switch&Tune™ technology and provides the ability to re-tune antenna across bands. It has an ultra-low loss SP4T switch and has a switching time of 5 µs.
Combining KYOCERA AVX extensive antenna systems expertise and proprietary algorithms, the EC646 can seamlessly adjust the characteristics of a wireless antenna to:
- Cover all 2G/3G/4G cellular, Bluetooth®, GSM, ISM and RFID bands
- Retune the antenna for frequency shifts
Reduce the antenna’s physical volume by up to 50 percent without performance trade-offs.
