TAT7457 - CATV 75 Ohm pHEMT Adjustable Gain RF Amplifier

General Description

The TAT7457 is a low cost RF amplifier designed for applications from DC to 2000 MHz.

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.

Key Features

  • Gain, return loss and bias externally adjustable On-chip active bias for consistent bias current and repeatable performance DC.
  • 2000 MHz bandwidth Low noise: typical NF < 2 dB to 1000MHz Flexible 5 V to 8 V biasing IDD(5V) = 120 mA typical in.
