TriAccess introduces RFICs for CATV hybrid applications

TriAccess Technologies of Santa Rosa, CA, USA, a fabless semiconductor company that provides CATV (cable TV) and FTTH (fiber-to-the-home) RFICs for amplifying high-quality multimedia content, has launched a series of RFICs that feature its patent-pending on-chip linearization for use in CATV hybrids.

The TAT8807 and TAT8857 are 75 Ohm RFIC amplifiers that work for applications operating at 50-1000MHz and 24V. Gain can be adjusted easily by varying external components. This flexibility enables CATV hybrid module makers to develop entire families of efficient modules around a single RFIC, says the firm.

TriAccess claims that its RFICs are the first to apply on-chip linearization fabricated in a single-die GaAs IC developed specifically for CATV networks. By incorporating on-chip linearization, the TAT8807 and TAT8857 yield higher gain (25dB) and consume very little power (350mA from a 24V supply) compared with other currently available products, it is claimed. The result is a compact, reliable, high-performance RFIC that takes up to one-third less power while maintaining high RF output. TriAccess says that it has developed this use of on-chip linearization for cable television applications in direct response to requests from key CATV customers for greater power efficiency.

“Both international cable operators and MSOs (multi-system operators) are looking to extend their existing infrastructures and increase the available services to their CATV subscribers,” says president & chief technology officer Chris Day. “Boosting the RF signal enables cable operators to carry more bandwidth-consuming services on their existing networks,” he adds. “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.”

Designed for use in CATV line amplifiers and CATV system amplifiers and distribution nodes, the new TAT8800 family of RFICs is fabricated using the commercial foundry GaAs process of TriQuint Semiconductor Inc of Hillsboro, OR, USA. By integrating amplifier and linearization functions, the TAT8800 family achieves both excellent 2nd- and 3rd-order distortion performance, TriAccess claims.

The new RFICs are being debuted and exhibited - along with TriAccess’ complete portfolio of products and solutions - by sales representative WaiTat Electronics Ltd and Mitron at the China Content Broadcasting Network (CCBN) Conference at the China International Exhibition Centre in Beijing (21-23 March).
