ASA303A Data Sheet
50 ~ 1200 MHz Gain Adjustable Trans-impedance Amplifier MMIC
1. Product Overview
1.1 General Description
ASA303A, 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 -8 dBm to +2 dBm
