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.
