Medium Gain Broadband Amplifier DC - 54 GHz

The CGY2144UH/C2 is a broadband distributed amplifier designed especially for OC-768 (43 Gb/s) based fiber optic networks. The amplifier can be used as a Transimpedance Amplifier (TIA) or either as a driver amplifier for Electro-Absorption Modulator (EAM). This amplifier can also be used as a flexible multi-purpose gain block.

This device features single ended RF input and output and operates with a power consumption of typically 500 mW. It requires only a single 5 V supply via on-chip bias network and a minimum number of external components.

The MMIC is manufactured using a qualified 0.13 μm pHEMT GaAs D01PH technology. The D01PH process is one of the European Space Agency (ESA) European preferred part list (EPPL) technologies.
