Description
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.

Features
■ Flat response, ±0.5 dB
■ Frequency response up to 1 GHz
■ High responsivity:
    — >0.85 A/W at 1310 nm
    — 0.95 A/W at 1550 nm
■ Internal current gain, 6 dB (typ.)
■ Up to 3 dBm max. continuous received power (6 dBm max.)
■ 75 Ω impedance-matched

Applications
■ Broadband CATV receivers requiring high input power for improved performance
