Newport1.2 to 10 GHz? Biased AC Coupled Optical Receivers

These free space photoreceivers consist of high speed Si, GaAs or InGaAs photodetectors with a built-in amplifier with up to 26 dB of gain. They are excellent for viewing rapid modulation of low-power CW lasers or other light sources in the µW regime. The detectors are AC coupled and feature a bandwidth ranging from 1.2 GHz up to 10 GHz.

特征

Silicon Optical Receiver

The 818-BB-21A features a 0.4 mm diameter silicon photodetector with a wavelength range of 300 to 1100 nm. 
This 24 V biased free space receiver has an acceptance angle of
10°.
The
Amplified PIN Photodetector
utilizes the photovoltaic effect to convert optical power into an electrical current.

InGaAs Optical Receiver

The 818-BB-30A features a 0.1
mm diameter InGaAs
photodetector with a wavelength range of 1000 to 1600 nm. 
This 24 V biased free space receiver has an acceptance angle of 20°.
The
Amplified PIN Photodetector
utilizes the photovoltaic effect to convert optical power into an electrical current.

Measure Pulsewidth or Frequency Response

These high speed detectors make a great free space
front end for an scope or spectrum analyzer.
When terminated into 50? into an oscilloscope, the pulsewidth of a laser can be measured. When terminated into a spectrum analyzer, the frequency response of a laser can be measured.

Optical Post Mounting

An 8-32 threaded hole at the bottom of 818-BB biased photoreceivers allows for optical post mounting.

Handle With ESD Care

These detectors are very susceptible to damage by electrostatic discharge (ESD). Please use ESD protective measures, like the FK-STRAP , when unpacking and handling these devices.
