2522 Microwave Packaged Photodiode
The 2522 packaged photodiode incorporates a high-speed planar
PIN photodiode to provide a highly reliable, high-power photodiode
component. This package is well suited for receiver applications
with optical preamplification. The diode is well matched over the
operating frequency band, thereby simplifying high-speed
integration.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are
absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in
excess of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for
extended periods can adversely affect device reliability.
