PRODUCT DESCRIPTION
The ACA2402 is a highly linear, monolithic GaAs RF
amplier 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 ampliers that are optimized
for exceptionally low distortion and noise gure. A
S7 Package
16 Pin Wide Body SOIC
with Heat Slug
hybrid equivalent that provides at 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.

Table 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.
Table 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 ampliers 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
specications.
