AMT8650 is a 10Gb/s optical receiver from ANADIGICS company. It has the characteristics of low cost, high performance, high bandwidth and high gain. The product adopts a 5-pin high-density package and is suitable for SONET OC-192/SDH STM-64 and 10Gb/s Ethernet applications.
The AMT8650 provides a high‑performance PIN photodiode and low‑noise, high‑gain transimpedance amplifier in a hermetic 5‑pin package. It supports 10 Gb/s operation over 1250‑1620 nm wavelength range and is suited for SONET OC‑192/SDH STM‑64 and 10 Gb/s Ethernet applications.
Key electrical specifications include a typical sensitivity of –19 dBm, overload handling up to 3 dBm, and a small‑signal transimpedance gain of 10 kΩ with an 8.5 GHz 3‑dB bandwidth. The device is offered in several package options, including ball‑lens and SC/APC pigtail variants, and can be mounted on evaluation boards for testing.
