40 GHz Linear InGaAs PIN, Wide Temperature Qualified (PD-40-TQ)

Data Sheet

The Optilab PD-40-TQ is a highly linear, 40 GHz bandwidth InGaAs PIN photodetector that is ideal for use in O/E front-ends requiring wide band frequency response.

Product Overview

The Optilab PD-40-TQ is a highly linear, 40 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 1000 nm through 1650 nm wavelength range, and assures a 40 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 50 mW. The PD-40-TQ is available in a standard 2-pin package with K output connector for ease of assembly, and can be ordered with or without the external protective housing, or with FC/APC connectors for standard. Contact Optilab for more information.
