ANADIGICS Expands Industry's Most Efficient 4G LTE Power Amplifier Family



ANADIGICS' New HELP4(TM) Power Amplifiers Bring Industry-Leading Efficiency to Fifteen LTE Bands Worldwide

Warren, NJ - ANADIGICS, Inc. (Nasdaq: ANAD), a world leader in radio frequency (RF) and mixed signal semiconductor solutions, today announced the expansion of its fourth generation High-Efficiency-at-Low-Power (HELP4(TM)) LTE (Long Term Evolution) power amplifier (PA) family. The ALT67xx series HELP4(TM) 4G PAshave three selectable power modes to deliver the power and linearity required for 4G mobile devices over a full range of operating conditions.

ANADIGICS' HELP4(TM) 4G PAs use the Company's exclusive InGaP-Plus(TM) technology to achieve optimal efficiency across low-range and mid-range output power levels and provide the lowest quiescent currents in the industry. The ALT67xx series deliver industry-leading efficiency to extend battery life in handsets, smart phones, tablets, netbooks, and notebooks. The Company's HELP4(TM) PAs also provide highly efficient operation in WCMDA, HSPA and HSPA+ systems.

"The rapid deployment of LTE networks is enabling manufacturers to design new mobile devices with unprecedented access to multimedia content," said Marcus Wise, Vice President of Wireless RF Products at ANADIGICS. "Our expanded HELP4(TM) power amplifier family supports fifteen LTE bands, enabling users around the world to experience the full potential of wireless 4G on long-lived mobile devices."

A report published by the Global Mobile Suppliers Association (GSA), in January 2011, confirmed 128 operator commitments to deploy commercial LTE systems in 52 countries. The number of operators investing in LTE deployments and trials increased by more than 140% in just one year, making LTE the fastest developing system in the history of mobile telecommunications.
