PRODUCT DESCRIPTION
The ACA2402 is a highly linear, monolithic GaAs RF
amplifier that has been developed as an alternative
to 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
RF Input
hybrid equivalent that provides flat gain response and
excellent input and output return loss over the 40 to
1000 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.

APPLICATION INFORMATION
Figure 16: Evaluation Board Layout
Notes:
1. Via holes should be 35 mils (0.89 mm) in diameter, and plated to 1 mil (0.025 mm) thickness. They need not be solderfilled.
2. WARNING: Due to the power dissipation of this device, the printed circuit board should be mounted/attached
to a heat sink.
3. More assembly details, such as via hole diameters, via spacing, solder paste application, and soldering recommendations are provided in the application note entitled, “Thermal Management of ANADIGICS’ Surface Mounted Amplifiers”.
