PRODUCT DESCRIPTION
The ACA2407 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
RF Input
excellent input and output return loss over the 40 to
1000 MHz CATV downstream band is formed when
one ACA2407 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. Pins 11 and 14 are bias feeds for input amplifiers 1A and 1B. No external
DC bias should be applied.
3. Pins 10 and 15 receive DC bias directly from pins 11 and 14. No other
external bias should be applied.
