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

■ 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
