Ethertronics Further Revolutionizes the RF Front End with New Addition to Its EtherChip™ Portfolio of Antenna Tuning Chips
BARCELONA, Spain & SAN DIEGO --(Business Wire)--
During the 2014 GSMA (News - Alert) Mobile World Congress in Barcelona, Ethertronics,
a leading technology company enabling innovative antenna and RF system
solutions to deliver the best connected experience, unveiled EtherChip™
EC303™. EC303 is the first in the RF Switch Antenna Tuning Chip™ series
that takes Ethertronics even further into the RF Front End (RFFE)
system. It is designed for a variety of applications including wireless
phones, tablets, notebooks, M2M products, the Internet of Things and
other wireless devices.
EtherChip EC303 disrupts the status quo in device design by
re-engineering a traditional SP12T switch from the antenna perspective,
combining antenna switching, antenna tuning and embedded RAM (News - Alert)
functionalities on a single substrate, without sacrificing performance.
Using a 180nm SOI CMOS foundry, EC303 combines three SP4T RF switches
with two 4-bit digitally tunable capacitors and embedded RAM to deliver
and maintain high performance across all 2G and 3G bands, as well as the
stringent, low 4G LTE (News - Alert) bands.
With carrier aggregation on the rise, there is a significant demand for
a single antenna to cover a wider frequency range. The antenna is the
only RF sensor within a wireless device and reacts differently in high
band and low band to environmental loading (hand, head, close proximity
of objects, etc.). These differences pose a major challenge for OEMs to
make it all work and deliver a superior user experience. A multi-feed
antenna offers a distinct advantage since it enables independent control
of frequency band subsets across all 2G/3G/4G LTE bands in a more
efficient way. With EC303, Ethertronics solves these challenges for OEMS
by delivering an antenna-centric RF silicon chip capable of decreasing
optimization time and challenges, as well as meeting carriers' targeted
specs, and ultimately fulfilling the mobile user experience. Like other
products in the EtherChip portfolio, EC303 is a critical step toward
enabling a smarter AFEM (Antenna Front End Module) for cost-effective,
efficient and scalable solutions with its embedded RAM. This is critical
given that the space available for the RFEE gets squeezed each year
forcing component vendors to reduce the overall footprint for RF
components inside devices while asking for more complex band coverage
and configuration flexibility.
"With EtherChip EC303, we are once again disrupting the status quo by
providing OEMs with a single solution that will transform how they
ultimately approach device design," said Laurent Desclos, president and
CEO at Ethertronics. "EC303 simplifies the design process for OEMs since
it's a single, complete solution that allows them to support carriers'
requirements and ultimately deliver an enhanced user experience. OEMs no
longer need to grapple with integrating RF components that aren't
optimized to seamlessly work with one another. Given that EC303 is an
antenna-centric RF silicon chip, it is able to provide the integration
of complete antenna tuning and multiband signal path switching for
today's challenging mobile platform RFFEs, along with all control, bias
and memory housekeeping functions. This antenna systems approach sets us
apart from other antenna companies and positions us as a true antenna
system player. EC303 draws on Ethertronics' more than 14 years of global
antenna integration experience, providing a single source for all
antenna system aspects including the antenna, the related silicon and
the application software tools to manage them. It underscores our
continued commitment to helping our OEM customers come to market with
smarter, high-performance products."
Like Ethertronics' recently announced EtherChip EC949™ and EC975™, EC303
also features embedded RAM. This feature makes EC303, EC949 and EC975
the industry's only antenna tuning chips with built-in memory
capabilities. Embedded RAM allows the tunable capacitor and/or the RF
switch to be controlled through the application layer, instead of the
baseband software. OEMs will benefit from much easier integration, as
they won't need to modify baseband software or add additional hardware.
Ethertronics also provides its proprietary application software to
optimize the process of integration.
EC303 has an operating frequency of 100 MHz to 3000 MHz, making it ideal
for 2G, 3G and lower 4G LTE band applications. All EtherChip products
use SOI technology making them easily scalable and portable. SOI is a
perfect alternative to higher cost technology. EC303 can be delivered as
a die or a packaged device.
EC303 additionally features a flexible control interface that is
OEM-selectable between SPI or MIPI protocols. This interface allows OEMs
and integrators to speed up the integration and testing. In addition, by
splitting the bands at the switch level, EC303 gains better control of
the antenna characteristics and optimization, simplifying RF switching
and RF switch linearity and insertion loss requirements. EC303 also
provides inter-band isolation and enables additional isolation from
multi-feed antennas, which eases requirements for carrier aggregation
In addition to EC303, Ethertronics offers multiple antenna switching
configurations with the same tunability, embedded RAM, software and
support offered by EtherChip products.
Ethertronics is showcasing EC303 and several of its other innovative
products at GSMA Mobile World Congress (News - Alert) and Showstoppers in Barcelona,
Spain. The company's EtherChip 2.0™, part of the EtherChip family of
products, has been shortlisted for the GSMA Global Mobile Awards and the
Telecoms.com (News - Alert) 2014 awards, both of which are being announced during
Mobile World Congress. To set up a meeting and learn more, please
