The gain of the TAT8807 and TAT8857 may be easily adjusted by varying external components, and this flexibility enables CATV Hybrid module builders to develop entire families of efficient modules around a single RFIC.

TriAccess Technologies’ RFICs are the first to apply on-chip linearization fabricated in a single-die GaAs integrated circuit developed specifically for CATV networks. By incorporating on-chip linearization, these RFICs provide a solution that consumes very low power and yields a higher gain than other currently available products. The result is a compact, reliable, high performance RFIC that takes up to one-third less power while maintaining high RF output. TriAccess, responding directly to the requests of key CATV customers for greater power efficiency, has pioneered this use of on-chip linearization for cable television applications.

“Both international cable operators and MSOs are looking to extend their existing infrastructures and increase the available services to their CATV subscribers,” said Chris Day, TriAccess Technologies president and CTO. “Boosting the RF signal enables cable operators to carry more bandwidth-consuming services on their existing networks. Boosting an entire distribution node, especially those with long trunk cabling and a large number of subscribers, can be very expensive and our lead customers for the TAT8807 and TAT8857 RFIC amplifiers recognize the value of these products for delivering higher performance at lower cost and lower power.”

TriAccess is utilizing TriQuint (TQNT) Semiconductor’s Commercial Foundry GaAs process for the fabrication of the TAT8800 product line. By integrating amplifier and linearization functions, the TAT8800 achieves both excellent 2nd and 3rd order distortion performance.

The TAT8807 and TAT8857 operate within a bandwidth of 50 – 1000MHz with a gain of 25dB and consume as low as 350mA from a 24v supply. The TAT8807 and TAT8857 will be debuted and exhibited – along with TriAccess’ complete portfolio of products and solutions, in TriAccess Technologies sales representative booths at the China Content Broadcasting Network (CCBN) Conference at the China International Exhibition Centre in Bejing, March 21, 2009 to March 23, 2009.
