Qorvo's TAT2814A 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 step 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.\nThe TAT2814A meets the stringent DOCSIS 3.0 output linearity specifications with extra margin to overcome additional losses before the output connector.\nThe TAT2814A is packaged in an industry standard 7x7 mm 48-pin QFN and consumes less than 5 watts between a 5 V input amplifier supply and an 8 V output amplifier supply. The TAT2814A utilizes proven GaAs pHEMT at Edge QAM optimized voltage to significantly reduce power consumption of the output stage.\n
