Product specification

870 MHz optical receiver

with integrated gain control

CGO869

FEATURES

• Excellent linearity

• Extremely low noise up to 870 MHz

• Excellent flatness (straight line)

• Standard CATV outline

• Rugged construction

• Gold metallization ensures excellent reliability.

APPLICATIONS

• CATV systems operating in the 40 to 870 MHz

frequency range.

DESCRIPTION

Hybrid high dynamic range optical receiver amplifier

module in a SOT115AD package where the non-jacketed

fibre has no connector. Two of the module pins are for

connection to 24 V (DC), one for amplifier supply voltage

and the other for the photodiode bias.

The module contains a monomode optical input suitable

for wavelengths from 1290 to 1600 nm, a terminal to

monitor the photodiode current and an electrical output

with an impedance of 75

Ω. The gain of the amplifier can

be adjusted with one module pin.
