RF & Wireless Wireless Antenna Control Solutions With New Impedance Tuners for Smartphones and Mobile Devices RFMD unveiled its first impedance tuner, the RF1105, further expanding the Company‘s industry-leading portfolio of antenna control solutions. RFMD‘s programmable RF1105 functions as a tuner sub-system across all LTE frequency bands up to 2.7 GHz, providing antenna feed matching over a wide frequency range. This simplifies antenna design and enables smartphone and mobile device OEMs to optimize antenna power and sensitivity while also maximizing battery life. As frequency bands proliferate, cellular antennas are required to operate over wider bandwidths, greatly increasing the need for RFMD‘s impedance tuners. According to industry analyst firm Strategy Analytics, the proliferation of multi-band LTE devices is expected to drive phenomenal growth in shipments of antenna tuning components, reaching 1.8 billion units per year by 2018. Due to its unique topology, the RF1105 offers broad symmetric tuner gain and linear performance for optimal power transfer to the antenna, improving total system efficiency, even under the most adverse operating conditions in multi-band LTE and HSPA+ applications. Like RFMD‘s antenna tuners, its impedance tuners improve RF system efficiency between the transceiver and the antenna element. While RFMD‘s antenna tuners optimize radiated efficiency by adjusting or tuning an antenna‘s resonant frequency, its impedance tuners optimize power transfer to the antenna. Farsens Presents the Magneto, a Battery Free RFID Magnetometer Tag The Magneto from Farsens S.L., San Sebastián, Spain, is a battery free RFID sensor tag capable of transmitting a unique identifier and the associated magnetic field measurement data to a commercial EPC C1G2 reader without the need of a battery on the sensor tag. The device features a LIS- 3MDL magnetometer from ST Microelectronics with a measurement range from ±4 gauss to ±16 gauss. The tag comes in a variety of antenna designs and sizes to adapt the performance to the required application in the 860-960 MHz band. The reading distance for the battery free magnetometer tag is around 1.5 meters (5 feet) and it can be embedded in a wide variety of materials such as plastics or concrete. Evaluation kits are available. ■ Farsens S.L. www.farsens.com Both are part of RFMD‘s portfolio of antenna control solutions, which also includes high-performance routing switches that optimize antenna selection and control and enhance cellular data throughput rates.
