LTE offers consumers the promise of faster speeds and better coverage. Device manufacturers are challenged to meet these promises due to the number of bands required for global operation and the shrinking space available for the antenna.
EtherChip 2.0 incorporates Ethertronics’ patented IMD technology with dynamic Impedance Matching and Band Switching by combining two tunable capacitors and a four-port switch within a very small form factor; leaving ample room and design flexibility within the device for other components. OEMs now have a single solution to integrate into their designs bringing more smarts to their wireless devices, providing optimal wireless connectivity across global 2G, 3G and 4G (LTE) bands, and speeding up their time-to-market. Additionally, EtherChip 2.0 enables carrier aggregation with high efficiency, especially to meet the requirements of intra- and inter-band aggregation for LTE Advanced standard specifications, as it is able to access two or more bands simultaneously. OEMs will find real value in EtherChip 2.0 and mobile users will reap the performance benefits it provides
EtherModule 1.0™ integrates Ethertronics’ innovative active antenna, RF systems and chip technology into a turnkey plug-and-play module to provide maximum performance and reliability for M2M and other wireless devices. EtherModule 1.0 combines Ethertronics’ advanced antenna architecture and EtherChip 1.0™ tunable capacitor on a printed circuit board for easy integration by wireless product designers. An industry first, EtherModule 1.0 has a typical dynamic range of 20dB to deliver maximum performance across a wide range of frequencies and use cases. Given the combination of closed loop functionality with a proprietary algorithm integrated in conjunction with a microprocessor, the module is capable of dynamically sensing and optimizing the antenna system, without external control signals from the device. This approach provides tuning capability – seamlessly adjusting the characteristics of the antenna to its dynamic requirements, including frequency shift, hand, head and environmental effects, or more bandwidth. As a true, turnkey plug-and-play antenna system that can be integrated into M2M devices, EtherModule 1.0 minimizes the need for additional engineering design and gets products to market faster. Measuring 35x15x10 mm, EtherModule 1.0 is able to cover one frequency or a wide range of frequencies depending on the needs – from 100 MHz to 3 GHz – including 2G, 3G and 4G cellular as well as Bluetooth, ISM, WiFi and ZigBee. Its compact size and ability to cover a wide range of frequencies make it ideal for a variety of applications, including M2M, tablets and other wireless devices.
EtherChip 1.0™ leverages Ethertronics’ Air InteRFace Digital Conditioning™ (AIRFDC™) technology to provide tuning capacitance for the antenna system. EtherChip 1.0 can seamlessly adjust the characteristics of a cellular antenna for its dynamic requirements including retuning for frequency shift, hand or head effects, or more bandwidth. Ethertronics developed EtherChip 1.0 to give device OEMs powerful new options for turning the challenge of decreasing space into an opportunity. EtherChip is the first step in enabling a smarter Antenna Front End Module (AFEM), where a device’s entire RF front end resides in the space that once was occupied only by the antenna. As a result, systems designers can use EtherChip 1.0 to accommodate even the sleekest form factors, creating 3G/4G smartphones and tablets that stand out in the marketplace. All that the user notices is great performance, giving the device OEM another powerful market differentiator.
EtherSmart LTE 1.0™ Phone Adaptive Antenna Solution uses Active Impedance Matching techniques to resolve a number of issues in mobile devices. Active Impedance Matching techniques can reduce the antenna’s physical volume by 50 percent without compromising performance. This significant size reduction is critical, especially as additional antennas are integrated into the device and the battery size continues to grow. Alternatively, these techniques can be used to cover a wider bandwidth in the same antenna volume. Active Impedance Matching also speeds up time-to-market, since it allows more degrees of freedom in the antenna structure design phase. Unlike “passive” antennas that require tuning with each design iteration process, active antennas can dynamically re-tune themselves when changes are made to the device. This is important for OEMs especially as they battle it out to come to market with new devices ahead of their competition.
EtherBook 1.0™ leverages Active Band Switching techniques and is the only antenna available that can be integrated inside of a notebook. Band switching meets LTE’s multiple band challenge in that it is able to cover more than 13 bands for LTE global roaming. Since active band switching technology can handle significant spreads in bands, from the low 700 MHz U.S. bands to 2.7 GHz, this ability simultaneously allows both voice and data usage at the same time, all without compromising performance for the user. This is pertinent for carriers needing to harvest bands or make the most of any spectrum they can get their hands on. Band switching is also capable of bringing the smallest physical volume antenna systems to fit in the thinnest devices for consumers.
Different active technologies and techniques can be used as standalones or as complements to one another to achieve even better results.
Ethertronics continues to innovate active antenna systems to meet today’s and tomorrow’s wireless designs.
