The FMA3051 is a high performance 12.5-15.5 GHz Gallium Arsenide monolithic amplifier. It is suitable for use in point-tomultipoint communications, sat-com and electronic warfare applications. The die is fabricated using the Filtronic 0.25 m process. The balanced design offers high output power with low return losses. Power detection is achieved with an on-chip coupled detector associated with diode reference voltage. The circuit is DC blocked at both the RF input and the RF output.
