TAT7457 pHEMT RF Amplifier


The TAT7457 is a low cost RF amplifier designed for applications from DC to 2000MHz. The balance of low noise and distortion provides an ideal solution for a wide range of broadband amplifiers used in cable television applications such as optical receivers and low noise front ends. The TAT7457 features adjustable gain and return loss with an external feedback resistor.

 

Features
  • Gain, return loss, and bias externally adjustable
  • On-chip active bias for consistent bias current and repeatable performance
  • Low noise: typical NF < 2dB to 1000MHz
  • Low distortion
Applications
  • Single-ended and push-pull optical receivers
  • Low-noise drop amplifiers
  • Distribution amplifiers
  • Multi-dwelling units
  • Single-ended gain block

TAT6254B pHEMT RF Amplifier


The TAT6254B integrates two low noise, high gain trans-impedance amplifiers in a differential configuration followed by an output amplifier. It provides a low input impedance to minimize the effects of photodiode capacitances and stray impedance affects on gain flatness. The TAT6254B was designed as a general purpose FTTP receiver, and allows wide flexibility in setting gain, tilt, and bias levels. Gain control is accommodated with a low cost external PIN diode circuit placed between the input trans-impedance amplifier and the output amplifier.

Features
  • Ultra low noise / high gain
  • Ideal for QAM-dominated content
  • Can extend optical system link budget
  • 3.0 pA/rtHz EIN
Applications
  • High dynamic range FTTH
  • Radio Frequency over Glass (RFoG, GPON, FTTH)
  • Multi-dwelling unit TIA
  • Mini-node
