PRODUCT DESCRIPTION
The ACA2402E 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 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 ACA2402E 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.
