Description
The RG8G3122B is a dual‑channel, 150Gbaud linear transimpedance amplifier (TIA) for 800G and beyond integrated coherent receivers (ICRs). The device integrates two TIA signal paths for the I and Q channels. It is a high‑performance, low‑power, and compact design that enables an optical subassembly, such as micro‑ICR or IC‑TROSA, for use in small‑form‑factor (SFF) integrated optical modules.
