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.
