KYOCERA AVX EC646 Antenna Switch features Ether Switch and Tune™ technology and a 100Mhz to 3000MHz operating frequency range. The EC646 switch offers high-performance RF switching to help solve the challenges facing the wireless industry and product designers. This switch allows the RF front-end to cover global bands and seamlessly improve performance in a dynamically changing RF environment by employing active tuning. Global band coverage is provided 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. KYOCERA AVX EC646 Antenna Switch combines antenna system expertise and proprietary algorithms to adjust the characteristics of a wireless antenna to cover 2G/3G/4G cellular, BLUETOOTH®, GSM, ISM, and RSID bands, retune the antenna for frequency shifts, and reduce the antenna’s physical volume by up to 50%.
