PRODUCT DESCRIPTION
The ACA2461 is a highly linear low noise high gain
RF pre-amplifier module in the industry standard
SOIC-16 SMT package. Designed to drive D3.1
compliant power doublers in Deep Fiber Node CATV
infrastructure applications, the module consists of
two parallel amplifiers in cascade forming a push-pull
optimized for low noise, low distortion, high output
power per channel, and high TCP. Advanced GaAs
optimizes operating current making the module an
excellent choice for environmentally friendly “GREEN”
applications.

Storage Temperature
Stresses in excess of the absolute ratings may cause permanent damage.
Functional operation is not implied under these conditions. Exposure to
absolute ratings for extended periods of time may adversely affect reliability.
Notes:
(1) Pins 2, 4, 5 and 7 should be AC-coupled. No external DC bias should be
applied.
(2) Pin 6 should be AC-grounded and/or pulled to ground through a resistor for
current control.
(3) Pins 10, 11, 14 and 15 should have no other external bias applied.
