Anadigics unveils ProEficient InGaP PAs for 4G

Employing the firm's advanced indium gallium phosphide HBT MMIC technology, these modules are suited to for use in the world’s most widely used 3G/4G frequency bands

Anadigics has introduced the new ProEficient WCDMA / LTE power amplifier (PA) product family.

The company’s ProEficient PAs have been optimised for the next generation of 4G devices across all power levels. These products combine greater talk time in low-power mode with longer data application use in high-power mode. The result is an enhanced overall user experience and extended battery life across all operating conditions of modern smartphone and tablet devices, as well as lower overall system cost.



“4G devices enable users to tap into ultra-fast broadband speeds, resulting in greater data use,” notes Jerry Miller, vice president of business development and marketing at Anadigics. “This change in use patterns drives the power amplifier to operate more frequently in high power mode. By delivering outstanding efficiency in both high and low power modes, Anadigics’ new ProEficient power amplifiers are helping manufacturers set the standard for 4G battery-life.”

These PAs use the company’s exclusive InGaP-Plus technology to achieve outstanding efficiency at high and low power modes in order to maximize 4G battery-life without the use of a DC-DC converter.  The devices are also optimised for use with average power tracking to further increase efficiency and reduce current consumption at medium and low operating powers. 

In addition to outstanding efficiency, ProEficient power amplifiers deliver exceptional linearity to ensure a stable connection for clear voice and high-speed data. The first ProEficient PAs are available for use in the world’s most widely used 3G/4G frequency bands, such as bands 1, 2, 3/4/9/10, 5, and 8.

With a low quiescent current, Anadigics says this product family offer best-in-class linearity (ACLR1). They are LTE compliant, WCDMA, HSPA, and HSPA+ compliant and CDMA/EVDO compliant. The highly integrated 3 mm x 3 mm modules have Internal voltage regulation and integrated DC blocks on RF ports. They offer RF matching optimised for output power, efficiency, and linearity in a 50 Ω system.
