To ensure rugged and reliable operation, both LNAs are fully passivated. Both bond pad and backside metallisation are Ti/Au, which is compatible with conventional die attach, thermocompression and thermosonic wire bonding assembly techniques.
Microsemi has active MMIC product developments using both established GaAs and emerging GaN semiconductor technologies.
According to Strategy Analytics the addressable market for GaAs MMICs in Microsemi’s targeted markets such as defence and communications will be approximately $500 million by 2015. ABI Research also estimates the market for GaN MMICs to be approximately $100 million by 2018.
Microsemi’s highly-differentiated MMIC product attributes lead to faster design cycle times and smaller overall solution sizes in electronic warfare (EW), signal intelligence (SIGINT), military communication and other applications such as instrumentation equipment.
JDSU announces $100 million stock repurchase program
The company expects to invest in future growth and in strategic business development opportunities
JDSU’s Board of Directors has authorised a program to repurchase up to $100 million of the company’s common stock through open market or private transactions until June 27th, 2015, the end of the Company’s fiscal year 2015.
JDSU had $926.2 million in total cash as of March 29th, 2014 and generated $58.3 million in free cash flow during the first nine months of fiscal year 2014. The timing of repurchases and the number of shares repurchased will depend upon business and financial market conditions.
“We have achieved thirty consecutive quarters of positive operating cash flow in varying macroeconomic and industry conditions,” states Tom Waechter, JDSU’s president and chief executive officer. “We believe our strong balance sheet and our expectations for future cash flow generation provide JDSU the flexibility to enhance shareholder value through share repurchases while continuing to invest in future growth and in strategic business development opportunities.”
Microsemi moves into GaAs
and GaN MMIC market The products include wideband and Low Noise Amplifiers and switches for a broad range of applications
Microsemi has announced its entry into the monolithic microwave integrated circuit (MMIC) market space.
Building on its history in RF, microwave and millimetre wave solutions, this new portfolio initially comprises sixteen products spanning DC-40GHz. It includes wideband amplifier, low noise amplifier and switch products designed for the defence, communications, instrumentation and aerospace industries.

The MMA016AA DC- 15GHz amplifier has a power-selectable feature that allows customers to adjust power consumption based on the requirements of a particular application.
“Leveraging Microsemi’s extensive experience and capabilities in these markets has allowed us to work closely with industry-leading customers to define and develop products that solve engineer’s problems in new and creative ways,” says Ray Crampton, MMIC product line director, Microsemi. “Response to our initial MMICs has been exceptional and we are aggressively working to expand our offering with numerous active developments in both GaAs and GaN-on-SiC technologies.”
Microsemi’s new MMIC products include several differentiating factors that include:
The MMA001AA DC-20GHz wideband amplifier has positive gain slope with over 17dB gain at 20GHz.
The MMS002AA single-pole, double-throw switch features approximately 45dB of isolation from DC-20GHz.
