870 MHz optical receiver
with integrated gain control
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.
