TriQuint Semiconductor Inc., a leading RF solutions supplier and technology innovator, released its new gallium nitride (GaN) integrated power doubler with superior performance for fast-growing CATV infrastructure.

TriQuint’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 fiber to the premises (FTTP) systems will be displayed at ANGA COM, Europe’s premiere broadband trade fair in Cologne, Germany (June 4-6).

TriQuint has also released its new gallium arsenide (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 the highest output 12V GaAs solution 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,” said 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 fiber 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, said 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.”

TriQuint’s innovative CATV / FTTH products deliver improved system-level performance and are 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.
