Broadband wireless and wireline communications component maker Anadigics Inc of Warren, NJ, USA has begun high-volume production shipments of its AWT6530 quad-band ProVantage power amplifier (PA), which is compatible with chipsets from leading suppliers including MediaTek, HiSilicon and Qualcomm.
ProVantage solutions offer high power mode efficiency, linearity and reduced system costs, says the firm. By leveraging Anadigics' unique quad-band architecture, the new AWT6530 PA also delivers integration that minimizes space requirements in mobile devices, it adds.
"Smartphone, tablet and datacard manufacturers increasingly value power amplifier solutions that integrate innovative features and excellent performance into compact packages," says Jerry Miller, senior VP of cellular products. "Our new AWT6530 quad-band ProVantage power amplifier is optimized to answer this challenge by providing an industry-leading blend of value, performance and space-saving integration," he adds. "The AWT6530 has broad applicability, validated by design wins at multiple OEMs, and is a key element of our growth strategy in China and emerging markets."
ProVantage power amplifiers leverage the firm's patented InGaP-Plus technology to achieve high performance and integration. The power amplifiers help to extend battery life by offering two selectable bias modes that optimize efficiency for low and high output power levels, as well as a shutdown mode with low leakage current. The AWT6530 quad-band power amplifier delivers 40% power-added efficiency (PAE) operating in UMTS bands 1, 5 and 8 and 42% PAE in band 2. Two independent amplification chains provide high performance for each band.
ProVantage solutions are also 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. The ProVantage power amplifiers also provide high linearity to maintain maintain stable, high-throughput 3G and 4G cellular connectivity and high data throughput.
ProVantage solutions are offered in compact 3mm x 4mm x 0.9mm 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.
