Anadigics launches ProEficient WCDMA/LTE PAs for 4G devices

RF and mixed-signal semiconductor maker Anadigics Inc of Warren, NJ, USA has launched the ProEficient WCDMA/LTE power amplifier (PA) product family, optimized for the next generation of 4G devices by delivering efficiency across all power levels.

The firm claims that the new PAs uniquely combine greater talk time in low-power mode with longer data application use in high-power mode, resulting in 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,” says Jerry Miller, VP of business development & marketing. “This change in use patterns drives the power amplifier to operate more frequently in high-power mode,” he adds. “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.”

ProEficient power amplifiers use the firm’s exclusive InGaP-Plus technology to achieve what is reckoned to be industry-leading efficiency at both high and low power modes – as well as low quiescent current - in order to maximize 4G battery-life without the use of a DC-DC converter. The power amplifiers are also optimized for use with average power tracking (APT) to further increase efficiency and reduce current consumption at medium and low operating powers.

ProEficient power amplifiers also deliver what is claimed to be best-in-class linearity (ACLR1) to ensure a stable connection for clear voice and high-speed data.

The 3mm x 3mm package of the PAs integrates internal voltage regulation, integrated DC blocks on RF ports, and RF matching (optimized for output power, efficiency and linearity in a 50-Ohm system).

The first ProEficient PAs are available for use in the most widely used 3G/4G frequency bands (such as bands 1, 2, 3/4/9/10, 5 and 8) as follows:

• the 1920-1980MHz AWT6651 for Band 1 has efficiency of 48% at +28.5dBm and 23% at +17dBm, and linearity (ACLR1) is -40dBc at +28.5dBm;
• the 1850-1915MHz AWT6652 for Band 2, 25 has efficiency of 48% at +28.3dBm and 23% at +17dBm, and linearity (ACLR1) is -40dBc at +28.3dBm;
• the 1710-1785MHz AWT6654 for Band 3, 4, 9 & 10 has efficiency of 48% at +28.6dBm and 23% at +17dBm, and linearity (ACLR1) is -40dBc at +28.6dBm;
• the 814-849MHz AWT6655 for Band 5, 18 & 26 has efficiency of 47% at +28.3dBm and 22% at +17dBm, and linearity (ACLR1) is -40dBc at +28.3dBm; and
• the 880-915MHz AWT6658 for Band 8 has efficiency of 47% at +28.5dBm and 22% at +17dBm, and linearity (ACLR1) is -40dBc at +28.5dBm.

The ProEficient PAs are compliant with LTE; WCDMA, HSPA and HSPA+; and CDMA/EVDO. Samples are available now for qualified programs.
