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
Trans-impedance Gain Adjustable from 35 dB to 5 dB @ Vctrl = 0.0 ~ 3.3 V
Gain Flatness: ±1.55 dB over Vctrl = 0.0 ~ 3.3 V @ 50 ~ 860 MHz,
±1.65 dB over Vctrl = 0.0 ~ 3.3 V @ 50 ~ 1000 MHz,
±1.65 dB over Vctrl = 0.0 ~ 3.3 V @ 50 ~ 1200 MHz
Output Power: 84 dBV @ CENELEC-42, 82 dBV @ PAL-98
Single +5 V, 245 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
