TriQuint’s GaAs pHEMT products in the MSL’s landing radar included the TGL4203-SM attenuator, TGA4517 Ka-band RF power amplifier and the TGC1430G frequency tripler. These are all fabricated using TriQuint’s 0.25µm technology.
into high performance products that add real value for customers.
Infinera PICs exceed a billion hours of operation
The firm’s indium phosphide (InP) devices have shown that reliability is critical as operators leverage PICs for cost-effective super-channel solutions to scale Intelligent Transport Networks

Infinera says its InP photonic integrated circuits (PICs) recently surpassed one billion hours of failure-free operation in live networks worldwide.
This achievement underscores the reliability of Infinera’s PICs and the key role they play in creating Intelligent Transport Networks.

Also used was the TGA4508, a Ka-band low-noise amplifier that utilised a 0.15 µm TriQuint process.
This figure is a cumulative total for all of the PICs that Infinera has shipped to customers since late 2004 in the Infinera DTN and DTN-X platforms. PICs are deployed by 109 customers in 67 countries around the world to light over one million kilometres of fibre and provide over three petabits per second of transmission capacity.
“This achievement is a very significant milestone for Infinera,” says Rick Talbot, Current Analysis. “It demonstrates that photonic integration offers the same kind of benefits in reliability as silicon integration for electronics has demonstrated over the past 50 years. This reliability is critical as operators leverage PICs for cost-effective super-channel solutions to scale Intelligent Transport Networks.”

Before assembly into the MSL, TriQuint devices endured an arduous space qualification screening process which far exceeds requirements of typical commercial or defence programs.
“The Mars Science Laboratory is not the first NASA mission for our technology, but it’s surely one of the most exciting for the design team and all of us at TriQuint,” says James Klein, Vice President and General Manager of Infrastructure and Defense Products. “When the customer is NASA, the location is Mars, and the end user is a precedent-setting, history-making spacecraft, the word ‘exciting’ takes on a whole new meaning.”
TriQuint’s portfolio of space-qualified products demonstrates a continuing commitment to reaching further, turning advanced research and development
“We are excited to make this announcement, as it demonstrates that Infinera has revolutionised this marketplace with our photonic integrated circuits,” adds Dave Welch, Infinera Co-Founder, Executive Vice President and CTO. “Our solutions, based on photonic integrated circuits, provide global service providers with the reliability they demand to operate Intelligent Transport Networks.”
Infinera continues to lead the long-haul 100G optical transport market since its entry in Q2 2012. The company announced last month that the Dell’Oro Group ranked Infinera number one for the first quarter of 2013 in the global long-haul 100G wavelength division multiplexing (WDM) market.
The Intelligent Transport Network is an evolution of Infinera’s Digital Optical Network and is showcased by the DTN-X platform and the Infinera portfolio. The DTN-X is engineered to be scalable and provide investment
