0 with +4 dB typical performance margin < 5 Watt nominal power consumption Low-reflection differential input/output stages 18 dB typical return loss across entire gain range Variable gain attenuator: 18 dB typical range 30 dB typical max gain +49 dBm typical OIP3 2.
7 dB typical noise figure Typical Input stage bias: 5 V, 290 mA Typical Output stage bias: 8 V, 415 mA 48-pin 7x7mm QFN laminate package  General Description The 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.
The TAT2814A meets the stringent DOCSIS 3.
0 output linearity specifications with extra margin to overcome additional losses before the output connector.
The TAT2814A is packaged in an industry standard 7x7 mm 48-pin QFN and consumes 5 W between a 5 V input amplifier supply and an 8 V output amplifier supply.
The TAT2814A utilizes proven GaAs pHEMT to optimize performance and cost.
It allows the designer to optimize output stage voltage to significantly reduce power consumption in Edge QAM applications.
