Anadigics Expands 4G LTE Power Amplifier Family
The firm says its new HELP4 PA modules are the most efficient in the industry and can be used in fifteen LTE bands worldwide.
Anadigics, a provider of radio frequency (RF) and mixed signal semiconductor products, has expanded its fourth generation High-Efficiency-at-Low-Power (HELP4) LTE (Long Term Evolution) power amplifier (PA) family.
The ALT67xx series HELP4 4G PAs have three selectable power modes to deliver the power and linearity required for 4G mobile devices over a full range of operating conditions.
Anadigics says these devices provide the highest PAE and lowest quiescent current in the industry.

A spokesperson for Anadigics said, “We have witnessed how battery-life remains a key challenge as designers adopt new wireless technologies that provide greater data speeds and enable richer multimedia content. Anadigics continues to help mobile device manufacturers face the latest 4G challenge, by providing the world's most efficient LTE power amplifier.”
Anadigics’ HELP4 4G PAs use the Company’s exclusive InGaP-Plus 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 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, VP of Wireless RF Products at Anadigics. “Our expanded HELP4 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.
Anadigics says the average current consumption shows a reduction of 30%, compared with previous generation PAs and also has three mode states to achieve exceptional power-added efficiencies at low-range and mid-range output power levels.
The series has a low quiescent current of less than 4 mA and the firms says it has the best-in-class linearity at maximum output power. The highly integrated module has a footprint of 3 mm by 3 mm by 1 mm. It has integrated DC blocks on RF ports and internal voltage regulation and an integrated “daisy chainable” directional RF coupler with 20dB directivity.
The complete family of products provides support for paired FDD and unpaired TDD LTE with an identical pin-out across the entire family.
Samples of the Anadigics HELP4 4G PAs are available now and evaluation kits are available upon request.
Anadigics will exhibit its communication equipment suited to 3G and 4G mobile devices at the 2011 Mobile World Congress from February 14-17 in Barcelona, Spain at STAND2C19, Hall 2.
