Anadigics expands 4G LTE PA family to support 15 bands worldwide

Broadband wireless and wireline communications component maker Anadigics Inc of Warren, NJ, USA has expanded its fourth-generation HELP4 (High-Efficiency-at-Low-Power) LTE (long-term evolution) power amplifier family with seven new models (to supplement the existing five models).

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.

As well as delivering a high level of Integration (including integrated DC blocks on RF ports, internal voltage regulation, and integrated ‘daisy chainable’ directional RF coupler with 20dB directivity, all in a 3mm x 3mm x 1mm footprint), Anadigics’ HELP4 4G PAs use the firm’s exclusive InGaP-Plus technology to achieve optimal power-added efficiency across low-range and mid-range output power levels and to provide what is claimed to be the lowest quiescent currents in the industry (less than 4mA).

Average current consumption for the ALT67xx series is reduced by 30% compared with previous-generation PAs. The efficiency can hence extend battery life in handsets, smart phones, tablets, netbooks, and notebooks, as well as providing highly efficient operation in WCMDA, HSPA and HSPA+ systems.

Joining the existing ALT6701 (1920–1980MHz, Band 1), ALT6702 (1850–1910MHz, Band 2), ALT6704 (1710–1785MHz, Bands 3, 4 & 9), ALT6712 (698–716MHz, Bands 12 & 17) and ALT6713 (777–798MHz, Bands 13 & 14; with no internal DC block on RF ports), the new PAs comprise the ALT6705 (815–849MHz, Bands 5, 6, 18 & 19), ALT6707 (2500–2570MHz, Band 7), ALT6708 (880–915MHz, Band 8), ALT6714 (777–798MHz, Bands 13 & 14), ALT6720 (832–862MHz, Band 20), ALT6738 (2570–2620MHz, Band 38) and ALT6740 (2300–2400MHz, Band 40).

“The rapid deployment of LTE networks is enabling manufacturers to design new mobile devices with unprecedented access to multimedia content,” says Marcus Wise, VP of Wireless RF Products. “Our expanded HELP4 power amplifier family supports 15 LTE bands, enabling users around the world to experience the full potential of wireless 4G on long-lived mobile devices,” he adds. The ALT67xx series PAs also provide support for paired FDD and unpaired TDD LTE spectrums.

A report from the Global Mobile Suppliers Association (GSA) in January 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 will exhibit at next week’s 2011 Mobile World Congress (stand 2C19, Hall 2) in Barcelona, Spain (14–17 February).
