Active antenna RF switch provides highest linearity for smartphones

Ethertronics has expanded its portfolio of active antenna RF switches with the launch of its high linearity for antenna switch LTE smartphones, devices and other Internet of Things, IoT, applications.

In addition to the very high linearity and small footprint, these fully integrated switch solutions support high data rates and broad frequency ranges.

With the proliferation of worldwide mobile spectrum, smartphone manufacturers are seeking new smart antenna solutions that can efficiently handle more than 20 cellular frequency bands, in addition to Wi‐Fi and Bluetooth. Ethertronics’ new RF antenna switches provide antenna tuning and band switching which are both key elements to solving these challenges.

Available today, the EC686 and EC646 are designed to meet the market demand for smartphones, minimizing the antenna footprint needed for today’s multiband LTE and LTE Advanced smartphones.

“Ethertronics’ new active antenna RF switches, with industry leading linearity, offer unprecedented performance levels for 4G and future 5G wireless applications," said Vahid Manian, Chief Operating Officer with Ethertronics. “Either of these new RF antenna switches, combined with our advanced active antenna architecture and algorithms, provides a complete smart antenna system unmatched in the market today. Our solutions continue to enable some of the fastest growing smartphones, devices and Internet of Things applications as the world becomes more connected.”

Ethertronics’ new active antenna RF switches can be used in various ways. These devices, along with Ethertronics’ antenna technology and algorithms, enable Ethertronics’ Active Steering technology providing revolutionary link margin improvements in cellular RF links. The EC646 and EC686 can also be used to actively band switch cellular antennas to cover additional frequency bands. By combining Ethertronics’ extensive antenna systems expertise, RFICs and proprietary algorithms, the devices can seamlessly adjust the characteristics of a wireless antenna including covering all 2G/3G/4G cellular, Bluetooth, GSM, ISM, RFID, Wi‐Fi bands, correcting the impedance mismatch and reducing the antenna’s physical volume by up to 50 percent without performance tradeoffs.

A medal for mobile medicine?
Medical services the world over are coming under great pressure to deliver high-quality healthcare and, at the same time control costs. Alongside this, patients are becoming far more involved in their wellbeing as well as wanting a high standard of healthcare with even greater convenience than before. As people are more mobile these days, mobile healthcare (mHealth) avoids the need to visit the doctor’s office and allows patients to provide health data to providers, as well as receive care, anywhere on the planet.
