RF Electronics M/A-COM Technology
Announces New 1 Watt Linear RF Driver Amplifier
M/A-COM Technology Solutions, a supplier of high performance analog semiconductor solutions, have introduced a new RF Driver Amplifier for MILCOM and infrastructure applications.
The MAAM-010617 is a 30dBm GaAs MMIC amplifier which exhibits high linearity over a wide input power range. Biased with a single +5V supply, the MAAM-010617 has a quiescent current of 420mA. The amplifier is tunable over the wide frequency range of 30 MHz to 4000 MHz, in order to optimize its performance based on the end application.
Packaged in a lead-free SOT-89 package, the MAAM-010617 is fabricated using an HBT process to realize a constant high linearity over a wide input power and frequency range. The operating bandwidth of this device can be optimized with selective off-chip components.
“The high linearity and frequency range of this part make it an ideal gain block in linear systems,” said Kevin Harrington, Aerospace and Defense Marketing Manager. “The SOT-89 standard package is a good thermally efficient package which is easy to handle during assembly for our customers.”

Anadigics ‘ PAs power new ZTE Android smartphones
The devices are manufactured using the firm’s unique indium gallium phosphide HBT technology
Anadigics is shipping production volumes of its AWT6621, AWT6624, AWT6625A, and AWT6628A fourth generation High-Efficiency-at-Low-Power (HELP4) power amplifiers (PAs) to ZTE.
The devices will be used in ZTE’s V889D, V788D, N788, N910, and PF200 smartphones.
The V788D, N788, N910, and PF200 feature a 3.5- inch screen, 5 megapixel camera, and Android 2.3 Gingerbread operating system. The V889D has a 4-inch screen and Android 4.0 Ice Cream Sandwich operating system.
The ZTE V889D is powered by the AWT6621 and AWT6628A power amplifiers and the V788 is enabled by the AWT6621 power amplifier (PA).
ZTE’s N788 features Anadigics’ AWT6625A power amplifier. The N910 is powered by the AWT6624. and the PF200 is powered by the AWT6624.
“We look forward to working with ZTE as it continues to develop innovative smartphones for the global wireless market,” says Michael Canonico, senior vice president of worldwide sales at Anadigics.
“The strength of our product portfolio coupled with our Asia-centric strategy demonstrates Anadigics’ commitment to both product and service excellence. Our world-class applications centres in China further support Anadigics’ growth initiative.”
Anadigics’ HELP4 4G PAs use the Company’s proprietary 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 AWT6621, AWT6624, AWT6625A, and AWT6628A power amplifiers are suited to WCMDA, HSPA and HSPA+ systems. They are designed to extend battery life in handsets, smart phones, tablets, netbooks, and notebooks.
Anadigics says its HELP4 PAs reduce average current consumption by 30%, compared with previous generation PAs. They also have three
