The CGY2112UH is a 10.7 Gb/s TransImpedance Amplifier (TIA), designed for use in optical reception systems.

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 die is manufactured using OMMIC’s 0.18 μm gate length PHEMT Technology. The MMIC uses gold bonding 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.
