Overview

The RG8G3122A is a dual-channel 128Gbaud linear transimpedance amplifier (TIA) for 800G and beyond integrated coherent receivers (ICRs).

The RG8G3122A integrates two TIA signal paths for I and Q channels. The high-performance, low power, and compact design of the RG8G3122A also enable optical subassembly such as u-ICR and IC-TROSA used for small form factor integrated optical modules.
