Description
The 2609B 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 better control of parasitics between the photodiode and the impedance-matching circuit.

Features
■ Flat response to ±0.5 dB
■ Frequency response up to 860 MHz
■ High responsivity:
    —>0.85 A/W at 1310 nm
    —0.95 A/W at 1550 nm
■ Internal current gain, 6 dB (typ.)
■ 75 Ω impedance-matched

Applications
■ Broadband CATV receivers
