ASA303A Overview
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.
