TAT7472A1F

Applications  Edge QAM Gain Stage  MDU Output  RF Distribution Amplifiers  AH22 Replacement Product Features  75 Ω, 50 MHz to 1218 MHz Bandwidth  Low Noise Figure: < 3 dB  pHEMT Device Technology  SOIC-8 Package  Enhanced Gain and Bandwidth  Adjustable Bias General Description The TAT7472A1F is a 75 Ω RF Amplifier designed for CATV use, but capable of operation up to 1218 MHz. The TAT7472 A1F contains two separate amplifiers for push pull applications. It is fabricated using 6-inch GaAs pHEMT technology to optimize performance and cost. Each amplifier contains on-chip active biasing. The bias current set point of each amplifier is adjustable with a single resistor from the input to ground. Typical supply voltage is +5 V, IMD performance and bandwidth can be enhanced with +5.5 V and +6 V operation.
