<2 GHz Amplified Photodetectors Data Sheet

<2 GHz Amplified Photodetectors

EOT's <2 GHz Amplified Photodetectors contain PIN photodiodes that utilize the photovoltaic effect to convert optical power into an electrical current and a fixed gain transimpedance amplifier allowing measurement of <1 mW input powers. When terminated into 50 Ω into an oscilloscope, the pulsewidth of a laser can be measured. When terminated into 50 Ω into a spectrum analyzer, the frequency response of a laser can be measured. EOT's <2 GHz Amplified Photodetectors come with their own wall plug-in power supply. Plugging a coaxial cable into the photodetector's BNC output connector and terminating into 50 Ω at the oscilloscope or spectrum analyzer is all that is required for operation.

Applications:

· Monitoring high repetition rate, externally modulated CW lasers

· Viewing <1 mW laser powers

Features:

· Built-in transimpedance amplifier
