The 2611A 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 control of parasitics between the photodiode and the transformer. Additionally, the 2611A is designed for superior distortion performance at up to 6 dBm (received) input power.
