Gigahertz-bandwidth, designed and built with microwave qualified parts and techniques
11HSP-High-speed Photodetectors
- 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%
