High-Speed Photodetector
High-Speed Photodetector
Fast Photodetector ALT-FD-47p:High speed Si photodiode with a low junction capacitance for sub ns pulse waveform measurements.
High speed InGaAs photodiode for nanoseccond and sub-nanoseccond pulse waveform measurements.
Applications:- Pulse shape measurements
- Pulse duration measurements
- Precise synchronization
- Mode beating monitoring
Fast Photodetector ALT-FD-180p:High speed InGaAs photodiode for ns and sub ns pulse waveform measurements.
Applications:- Pulse rorm measurements
- Pulse duration measurements
- Precise synchronization
- Mode beating monitoring
HSP-High-speed Photodetectors:High-speed compact Photodetectors for your applications.
Only gigahertz-bandwidth qualified components are used in those
high-speed photodetectors.
An impedance matched microstrip line is used to couple the diode’s
output to the output connector.
A microwave quality SMA electro-magnetic wave launcher is used to couple
the signal to the scope.
Each detector is tested using a 20-Ghz sampling scope and passed only if
the peak-to-peak distortion due to ringing is <4%.
