Broadband wireless and wireline communications component maker Anadigics Inc of Warren, NJ, USA says that its ProEficient and ProVantage power amplifiers (PAs) have been selected by multiple Chinese OEMs to enable wireless connectivity in new smartphone designs.
"According to a recent report by DigiTimes Research, the sequential annual growth rate in smartphone shipments from Chinese OEMs is expected to exceed 30% in 2014," notes president Dave Cresci. "Anadigics is well positioned to capitalize on this expected growth with design wins at several key OEMs, including Huawei, ZTE, Coolpad and Innos," he adds. "We anticipate that these new design wins for our ProEficient and ProVantage power amplifiers should enable a significant increase in our mobile products revenue at Chinese OEMs."
ProEficient and ProVantage solutions utilize Anadigics' patented InGaP-Plus technology to deliver high performance and integration. ProEficient power amplifiers also leverage the firm's unique design architectures to offer high efficiency across all power levels as well as low quiescent current to maximize battery life, enabling greater talk time and longer data application use. ProVantage power amplifiers are designed to combine high performance with space-saving integration and lower overall system cost. Both ProEficient and ProVantage also have compact packages with internal voltage regulation and integrated DC blocks on the RF ports to reduce PCB space requirements. RF matching is optimized for output power, efficiency, and linearity in a 50-Ohm system.
Both ProEficient and ProVantage are designed for use with an external switch mode power supply (SMPS) to support average power tracking (APT), which further increases efficiency and reduces current consumption at low and medium operating powers. Anadigics says that its complete portfolio of power amplifier solutions provides high linearity to ensure stable cellular connectivity and high-data-throughput 3G and 4G connections.
