PRODUCT DESCRIPTION
The ACA2402E 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 ACA2402E is cascaded
between two appropriate transmission line baluns.

T able 2: Absolute Mimimum and Maximum Ratings
ELECTRICAL CHARACTERISTICS
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.
T able 3: Operating Ranges
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.
The device may be operated safely over these conditions; however, parametric
performance is guaranteed only over the conditions defined in the electrical
specifications.
