Anadigics ships HELP4 LTE PA for ‘Revolution by LG’ smartphone

RF and mixed-signal semiconductor maker Anadigics Inc of Warren, NJ, USA is shipping production volumes of its ALT6713 fourth-generation High-Efficiency-at-Low-Power (HELP4) LTE power amplifiers (PAs) to LG Electronics.

Optimized for LTE applications, the ALT6713 is powering the Revolution by LG VS910 smartphone for Verizon Wireless. The feature-packed handset includes a large 4.3” capacitive touch screen, 1GHz Snapdragon processor, 5.0 megapixel rear-facing camera, 720p video capability, Android 2.2 operating system, and 4G LTE connectivity. The ALT6713 PA is also used to power LG’s VL600 USB LTE modem.

“The selection of Anadigics' power amplifiers for the Revolution by LG demonstrates the strength of the relationship forged between Anadigics and LG Electronics,” says Michael Canonico, Anadigics’ senior VP of worldwide sales. “We understand the challenges facing handset manufacturers today as the demand for power-hungry multimedia and high-speed data features continues to threaten battery-life,” he adds. “Anadigics has responded to these challenges by delivering the industry’s most efficient LTE power amplifier,” he claims. "We look forward to working with LG Electronics on the design of future platforms.” 

Anadigics says that its HELP4 4G power amplifiers use its exclusive InGaP-Plus technology to achieve optimal efficiency across low-range and mid-range output power levels. The ALT6713 helps improve battery life by combining high power-added efficiency (35% PAE @ +27.5dBm operating in the 777–798MHz Bands 13 and 14) with what is claimed to be the industry’s lowest quiescent current (3mA), reducing average power amplifier current consumption by 30% compared with previous-generation devices. 

A high level of integration in a 3mm by 3mm by 1mm footprint also incorporates internal voltage regulation and integrated ‘daisy chainable’ directional RF coupler.
