PHOTODIODE
GaAs PIN photodiode with preamp
G9842 series
TO-46 package, 0.85 µm, 2.5 Gbps
G9842 series is a family of high-speed receivers specifically developed for 0.85 µm band optical fiber communications. These devices
incorporate a high-speed, high-sensitivity GaAs PIN photodiode integrated with a high-speed preamp, allowing easy connection to a
latter-stage circuit. Lens window types are also available for efficient and easy coupling to an optical fiber.
