PRODUCT DESCRIPTION
The ACA2402 is a highly linear, monolithic GaAs RF
amplifier that has been developed to replace, in new
designs, standard CATV hybrid amplifiers. Offered
in a convenient surface mount package, the MMIC
consists of two pairs of parallel amplifiers that are
optimized for exceptionally low distortion and noise
figure. A hybrid equivalent that provides flat gain
response and excellent input and output return loss
over the 40 to 870 MHz CATV downstream band is
formed when one ACA2402 is cascaded between
two appropriate transmission line baluns.

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. No external DC bias should be applied.
3. Pins 11 and 14 are bias feeds for input amplifiers 1A and 1B. No
external DC bias should be applied.
4. Pins 10 and 15 receive DC bias directly from pins 11 and 14. No other
external bias should be applied.

Notes:
1. Via holes should be 35 mils (0.89mm) in diameter, and plated to 1 mil (0.025mm) thickness. They need not be
solder-filled.
2. WARNING: Due to the power dissipation of this device, the printed circuit board should be mounted/
attached to a heat sink.
