TriQuint's GaN & GaAs Power Doublers Boost CATV Performance

The firm has released GaAs (gallium arsenide) and gallium nitride products to speed up uninterrupted connectivity
TriQuint Semiconductor has released a new GaN integrated power doubler with superior performance for fast-growing CATV infrastructure.

The firm's new GaN MMIC amplifier offers high gain (24dB) and excellent composite distortion performance (CTB/CSO), which is a critical characteristic in multi-carrier CATV environments.

TriQuint solutions for cable TV infrastructure and fibre to the premises (FTTP) systems will be displayed at ANGA COM, Europe’s broadband trade fair in Cologne, Germany, taking place between June 4th and 6th.

TriQuint has also released its new GaAs power doubler that delivers the highest gain and output power among 'green' 12 Volt CATV amplifiers. The new amplifier provides RF output of +58dBmV/ch while consuming less than 8W, making it  one of the highest output 12V GaAs solutions in the CATV industry. Thanks to its low power consumption and gain, it can replace the equivalent of two legacy devices.

"TriQuint continues to expand solutions for cable TV infrastructure. Early customer feedback has been very positive on high output amplifier products," comments James L. Klein, Vice President and General Manager for TriQuint's Infrastructure and Defense Products. "Today's homes, schools and businesses are looking to cable and fibre operators to provide high speed uninterrupted connectivity to ensure access for digital education and entertainment. TriQuint’s GaN and GaAs product innovations are key enablers for the systems."

The growth of CATV technologies is important to delivering sought-after content, notes Directing Analyst for Broadband Access and Video, Jeff Heynen, of Infonetics Research.

"Cable operators are gaining significant traction with DOCSIS 3.0 in North America, Europe, Korea and Japan; they're in the early stages of rolling out video gateways that combine DOCSIS CPE with video transcoding capabilities to deliver whole-home, multi-screen service; we anticipate hearty growth for the devices over the next few years," says Heynen.

TriQuint says its innovative CATV / FTTH products deliver improved system-level performance. They sre offered as surface-mount, 40-pin 5x7mm QFN packages which drive cost-effective direct-to-board assembly.

Samples and evaluation boards are now available; both devices are production-ready.



AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
