RFMD Expands Industry-Leading Portfolio of Antenna Control Solutions With New Impedance Tuners for Smartphones and Mobile Devices
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.
"RFMD's impedance tuners greatly expand our industry-leading portfolio of antenna control solutions while also providing customers the programmability and efficiency needed to simplify and accelerate antenna design in their flagship smartphones and tablets," said
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. 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.
RFMD's impedance tuners provide a dynamic matching environment and can be programmed to offer optimal performance across multiple conditions and usage cases. With the RF1105, smartphone OEMs can design antennas for optimal radiated efficiency while also reducing the potential tradeoffs associated with fixed matching components. It is sampling now with lead customers, and volume production is expected to begin in the first quarter of 2014.
