EMCORE 2609B

DATASHEET | JULY 17, 2003
2609B Broadband Photodiode Module
The 2609B is a packaged impedance-matched photodiode module with
internal gain designed for use in optical broadband receivers in fiberoptic
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 impedancematching circuit.
Features
Flat response to + 0.5 dB
Frequency response up to
860 MHz
High Responsivity
>0.85A/W at 1310 nm
>0.95 A/W at 1550 nm

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.
