ASA306B Data Sheet
50 ~ 1200 MHz Gain Adjustable Trans-impedance Amplifier MMIC
1. Product Overview
1.1 General 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. The amplifier is available in a
QFN24 plastic encapsulated package and passes through the stringent DC, RF, and reliability tests.
1.2 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 dBV @ NTSC 79 channels
Single +5 V, 290 mA
1.3 Applications
FTTH
Optical Receiver
Distribution Amplifier
Drop-in Amplifier
1.4 Package Profile & RoHS Compliance
QFN24, 4x4 mm2, surface mount
RoHS-compliant
