Transimpedance Amplifier, 2.5 Gb/s

The CGY2102UH is a high performance 2.5 Gb/s transimpedance amplifier (TIA). Typical use is as a low noise preamplifier for lightwave receiver modules in optical fiber networks. The TIA gives an exceptionally good sensitivity and high gain. The device is intended to be used with a PIN or APD photodetector. There is a built in AGC function which limits the peak-to-peak output voltage and protects the device from optical input overload. The CGY2102UH/C2 can be assembled in a small form factor packages, such as TO-46 headers. The die is manufactured using the 0.18 ?m gate length pHEMT technology. The MMIC uses gold bond pads and backside metallization and is fully protected with silicon nitride passivation to obtain the highest level of reliability. This technology has been evaluated for Space applications and is on the European Preferred Parts List of the European Space Agency.
