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 microwave 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 operation-

al sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.
