A number of services are coming available with the increasingly efficient use of cable spectrum. Whether its Video on Demand, higher throughput DOCSIS data, or Switched Digital Video channels, the use of efficient and compact Edge QAM systems facilitates the successful system rollouts.
TriAccess Technologies has developed a product line of RFIC products specifically designed to meet the stringent RF requirements of DOCSIS based Edge QAM systems. TriAccess solutions saves up to 50% on power consumption and 1/3 on space requirements. The TAT7466, TAT7464, TAT7472, TAT7467, provide a complete set of options for low power consumption EdgeQAM. The energy savings thermally enable closer component spacing and smaller heat-sink areas for an overall reduced footprint.

For medium output low distortion applications, the TAT7464 (5V, 50-2600 MHz) and the TAT7466 (5 and 6V, 50-1000MHz), reduce power consumption by up to 50% in 3 stage Edge QAM applications. Using the core technology of the TriAccess Technologies single ended amplifiers (TAT7461 and TAT7460), these push pull amplifiers are ideally suited for Edge QAM initial stage as well as other medium output applications.
The TAT7467 is the breakthrough Edge QAM-optimized output amplifier providing a number of industry first designs. This RFIC saves approximately 40% on power consumption through the use of on-chip linearization, externally adjustable bias, and DOCSIS-specific design optimization.
The TAT7468 and TAT7469 provide ideal input stage performance saving 30-50% over current input stage solutions. The gain levels of these devices enable a two stage approach to the amplifier chain, saving further on space and power consumption.
