PRODUCT DESCRIPTION
The ACA2456 is a highly linear high output power RF
amplifier module in the industry standard SOIC-16
SMT package. Designed for Deep Fiber Node CATV
infrastructure applications, the module consists of
two parallel amplifiers in cascade forming a power
doubler optimized for low distortion, high output power
per channel, and very high TCP. A GaN output stage
utilizing patent pending Proven-Power™ circuitry
minimizes operating current making the module an
excellent choice for environmentally friendly “GREEN”
applications.

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.
