Transimpedance Amplifier, 10 Gb/s

The CGY2110UH/C1 is a 10 Gb/s TransImpedance Amplifier (TIA). Typical use is as a low noise preamplifier for lightwave receiver modules in optical fiber networks. The device is intended to be used with a PIN or APD photodetector and is capable of amplifying input current up to 2 mA p.p. at BER of 10-12.The circuit also exhibits exceptional sensitivity. A biasing circuit for PIN photodiode is integrated in the CGY2110UH.

The die is manufactured using 0.18 μm 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.
