SFT-0100 Datasheet, PDF (1/4 Pages) SIRENZA MICRODEVICES – Transimpedance Amplifier

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 F_T 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 transimped-
ance 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 sig-
nal (LOS) detection.
