DATASHEET | JULY 17, 2003 2611A Broadband Photodiode Module The 2609C 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 Additionally, the 2611A is designed for superior distortion performance at up to 6 dBm (received) input power Features Flat response, + 0.5 dB Frequency response up to 1 GHz High Responsivity >0.85A/W at 1310 nm >0.95 A/W at 1550 nm PIN Information Table 1.
