High Speed Photodetector, Battery Biased InGaAs Detector, 22 GHz

The 818-BB-36 High Speed InGaAs Detector is built from a free-space extended InGaAs photodiode with a 20 um active diameter and a fast <16 ps rise time. It works well in high-frequency heterodyne applications, time domain, frequency response measurements and monitoring output of ultrafast lasers.  It includes a built-in battery-powered 3V bias, an on-off switch and an SMA connector output. The batteries are easily replaceable and by disconnecting the detector from the oscilloscope input, when not in use, you can extend the lifetime of the batteries.
