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.
Additionally, the 2611A is designed for superior dis-
tortion performance at up to 6 dBm (received) input
power.
