SFT-0100

Preliminary Data Sheet Product Description Sirenza Microdevices’ SFT-0100 is a high performance heterojunction bipolar transistor transimpedance amplifier designed for 10/12.5 Gb/s SONET/SDH applications. The SFT-0100 uses high FT indium gallium phosphide device technology that delivers high transimpedance, large dynamic range, and a typical bandwidth greater than 10.5GHz. Performance is enhanced through the use of a patented circuit topology that reduces duty cycle distortion under high photocurrent conditions and allows high transimpedance with low DC power to be realized. The SFT-0100 is supplied in bare die form and includes a current monitor feature that can be used for fiber alignment or loss of signal (LOS) detection.
