Description

The 2611A is a packaged impedance-matched pho- todiode 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 exter- nal circuits due to control of parasitics between the photodiode and the transformer. Additionall y, the 2611A is designed for superior dis- tortion performance at up to 6 dBm (received) input power. Pin Information Table 1. Pin Descriptions
