Wireless and wireline communications component maker Anadigics Inc of Warren, NJ, USA says that its AWL9581 802.11ac front-end integrated circuit (FEIC), AWT6651 ProEficient power amplifier (PA), and ALT6702 HELP4 PA are enabling wireless connectivity in Samsung Electronics’ new GALAXY Note 3. The GALAXY Note 3 improves upon the Note II (which is also powered by Anadigics’ RF solutions) by providing a larger 5.7-inch HD Super AMOLED display, faster processor, slimmer size and longer battery life.
The GALAXY Note 3 is the latest in a wide range of Samsung mobile devices (including the S 4, S 4 Mini, Tab 3 and Mega) that are powered by Anadigics’ RF products, says president Dave Cresci. “We look forward to continuing our collaboration with Samsung on their next generation of phones and tablets,” he adds.
The AWL9581 5GHz FEIC, AWT6651 ProEficient PA and ALT6702 HELP4 PA all leverage Anadigics’ exclusive InGaP-Plus technology and patented design architectures. The firm’s 802.11ac FEICs combine a power amplifier, low-noise amplifier (LNA) and RF Tx/Rx switch on a single die (in a compact 2.5mm x 2.5mm x 0.4mm QFN package) to improve manufacturability and reliability. Also incorporating a high-accuracy integrated power detector and RF ports internally matched to 50 Ohms, this level of integration also reduces PCB space requirements and simplifies RF front-end design for faster time-to-market, says Anadigics. The complete family of 802.11ac FEICs offers ultra-low error vector magnitude (EVM) and noise figure performance in the toughest 802.11ac modulation formats, enabling extremely high data throughput. Anadigics claims that its WiFi FEICs deliver the industry’s lowest current consumption, extending battery-life in mobile applications.
ProEficient power amplifiers provide high efficiency across all power modes to extend 3G and 4G talk time and data use for longer overall battery life with or without the use of a DC-DC converter. The power amplifiers are optimized for use with average power tracking (APT) to further increase efficiency and reduce current consumption at medium and low operating powers. The compact 3mm x 3mm package incorporates internal voltage regulation and integrated DC blocks on the RF ports to reduce PCB space requirements. It also integrates high-directivity coupler for ease of system integration. RF matching is optimized for output power, efficiency, and linearity in a 50-Ohm system.
HELP4 power amplifiers offer three mode states to optimize power-added efficiency at low-range and mid-range output power levels. HELP4 PAs allow a high level of integration in a 3mm x 3mm footprint (with DC blocks on RF ports and internal voltage regulation) to save PCB space, as well as an integrated ‘daisy chainable’ directional RF coupler with 20dB directivity.
ProEficient and HELP4 power amplifiers also deliver what is claimed to be best-in-class linearity to ensure stable, high-throughput 3G/4G connections for clear voice and high-speed data usage.
