20 GHz Linear InGaAs PIN Photodetector, Temperature Qualified

The Optilab PD-20-TQ is a highly linear, 20 GHz bandwidth InGaAs PIN photodetector that is ideal for use in O/E front-ends requiring wide band frequency response. The coplanar waveguide photodiode design optimizes speed and sensitivity for the 1260 nm through 1610 nm wavelength range, and assures a 20 GHz frequency response necessary for digital and analog applications. The front-illuminated mesa-structured PIN design allows a high input power level of up to 40 mW. The PD-20 is available in a standard 2-pin package with SMA RF connector output for ease of assembly, and can be ordered with or without the external protective housing. Contact Optilab for more information.
