TriQuint touting new GaAs amplifiers for CATV
TriQuint Semiconductor is unleashing two new TriAccess amplifiers designed to replace multiple products in CATV systems.
Both products will be released in conjunction with the ANGA Cable Show, taking place in Cologne, Germany between June 12th and 14th, 2012.
TriQuint says its new devices are economical and built with its market-tested GaAs technology, offering greater functional integration and higher efficiency.
The TAT6281 variable gain receiver for single family units (SFUs) employs PIN diode variable attenuation to provide a consistent, low-distortion method of adjusting gain. TriQuint’s integrated module delivers low-noise RF performance while simplifying FTTH amplifier designs and reducing bills of materials (BOMs). The TAT6281 builds on the success of TriQuint’s TAT6254 product line, millions of which have been deployed in CATV / FTTH networks worldwide.

TriQuint’s new TAT2814A satisfies the DOCSIS 3.0 specification with more than 4dB (typical) margin. By integrating two stages of amplification and a variable gain attenuator, TriQuint says its TAT2814A can greatly simplify CATV RF design by reducing the number of discrete RF components. According to the company, other solutions require up to five-times the PCB space to deliver DOCSIS 3.0 performance while consuming up to twice the electrical power.
TriQuint’s new product solution is ideal for DOCSIS 3.0 output stage amplifier designs including Edge QAM and CMTS (cable modem termination system) applications. The TAT2814A is also ideally suited for Ethernet over Coax (EOC) supporting DOCSIS 3.0 PA levels.
