TAT2814A1L(2014) Datasheet PDF - TriQuint Semiconductor

General Description
The TAT2814A1L is an RFIC for DOCSIS 3.0 Output Sections, such as CMTS and Edge QAM. It combines a low-reflection differential input stage, a variable gain attenuator and an efficient output amplifier to provide significant reduction in power consumption and PC board space. It replaces circuitry requiring up to 10x the board space and 2x the power.
