2609B Broadband Photodiode Module
Description
The 2609B is a packaged impedance-matched photodiode module with internal gain designed for use in
optical broadband receivers in fiber-optic networks.
The patented impedance-match technology results in
improved gain-bandwidth product compared to external circuits due to better control of parasitics between
the photodiode and the impedance-matching circuit.

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.
