Description
Reliable planar InGaAs photodiodes are packaged in hermetically sealed cans with a flat glass window or a ball lens. Which allows to couple with a multi mode fiber efficiently through the ball lens cap. The KPDX4G has a built-in transimpedance preamplifier and bypass chip capacitors, and is encapsulated in a small TO-46 package. A pigtail type is available.
