RFMD reveals 9W GaN wideband power amplifier
The PA designed for use in CW and pulsed applications, employs the firm’s proprietary gallium nitride HEMT technology
RFMD’s new RFHA1006 is a wideband Power Amplifier (PA) designed for use in wireless infrastructure, RADAR, two-way radios and general purpose amplification.
With an output power of 9W,the device employs advanced heat-sink technology and has a 225MHz to 1215MHz instantaneous bandwidth. It is input Internally matched to 50Ω, typically operates at 28V and has an output power of 39.5dBm. The module also has a gain of16dB and power added efficiency of 60% and works in the temperature range -40°C to 85°C Large signal models are also available.
Skyworks in Globe 100 for fourth time in a row
The company was ranked 8th in the Boston Globe’s 2011 Listing of the best performing public companies in Massachusetts

Using an advanced high power density GaN semiconductor process, RFMD says these high- performance amplifiers achieve high efficiency, flat gain, and a large instantaneous bandwidth in a single amplifier module.
The device is suited to class AB operation for public mobile radio and can provide a PA stage for commercial wireless infrastructure. It can also be employed in general purpose Tx amplification, test instrumentation and in civilian and military radar applications.
This GaN transistor is packaged in an air cavity ceramic package for excellent thermal stability through the use of advanced heat sink and power dissipation technologies.
Ease of integration is accomplished through the incorporation of optimised input matching network within the package that provides wideband gain and power performance in a single amplifier. An external output match offers the flexibility of further optimizing power and efficiency for any sub-band within the overall bandwidth.
Skyworks Solutions, an innovator of analogue semiconductors enabling a broad range of end markets, has been named in the Boston Globe’s list of top performing public companies in Massachusetts for the fourth consecutive year. The Globe 100 ranking, which is now in its 24th year, is based on several financial factors including year-over-year revenue growth and profit margin, as well as return on average equity. For the first time in three years, the Globe 100 list features 100 companies. In 2010 and 2011, less than 100 companies qualified given the impact of the recession. “The positive momentum we are seeing in the economic recovery is illustrated by the Globe 100 returning to full strength,” says Shirley Leung, business editor at the Boston Globe.
“It’s a powerful testament to the resiliency of Massachusetts’ businesses.” “Skyworks is delighted to once again be recognised as one of Massachusetts’s most highly regarded and well performing companies,” adds David J. Aldrich, president and chief executive officer at Skyworks. “In 2011, Skyworks made significant progress towards solidifying our leadership position in analogue semiconductor solutions across a diverse set of applications. We are capitalising on consumers’ demand for mobile connectivity and are well positioned to benefit from the explosive growth in wirelessly-enabled platforms and services.” The Globe 100 ranks Massachusetts- based public companies based on financial data from the four quarters ending December 31, 2011. To be eligible, the company must be traded publicly for the entire 2011 calendar year on the New York
