Variable gain DOCSIS 3.0 amplifier
The RFIC meets the stringent DOCSIS 3.0 output linearity specifications with extra margin to overcome additional losses before the output connector.
Key specifications include meeting DOCSIS 3.0 requirements with +4 dB typical performance margin, 18 dB typical return loss across entire gain range, 30 dB typical maximum gain, +49 dBm typical OIP3, and 2.7 dB typical noise figure. Typical input stage bias is 5 V, 290 mA, while typical output stage bias is 8 V, 415 mA.
The TAT2814A comes in an industry standard 7- x 7-mm 48-pin QFN and consumes less than 5 W between a 5 V input amplifier supply and an 8 V output amplifier supply. The device utilizes proven GaAs pHEMT at Edge QAM optimized voltage to significantly reduce power consumption of the output stage.
