ASA306B - Gain Adjustable Trans-impedance Amplifier MMIC

Description

ASA306B, a trans-impedance amplifier (TIA) with voltage controlled attenuator, has a high linearity and low noise over a wide range of frequency up to 1.2 GHz, being suitable for use in the FTTH, optical receiver, distribution amplifiers, and drop-in amplifiers of CATV systems.

Features

  • Operating Frequency at 50 ~ 1200 MHz.
  • Optical Input from -7 dBm to +1 dBm.
  • EIN: 3.1 pA/rtHz.
  • Trans-impedance Gain Adjustable from 38 dB to 18 dB @ Vctrl = 0.0 ~ 4.3 V (adjustable).
  • Gain Flatness: ±1.2 dB over Vctrl = 0.0 ~ 4.3 V and 50 ~ 1200 MHz.
  • Output Power: 86 dBV @ NTSC 79 channels.
  • Single +5 V, 290 mA 1.3.
