PRODUCT DESCRIPTION
The ACA2407 is a highly linear, monolithic GaAs RF
amplier that has been developed to replace, in new
designs, standard CATV hybrid ampliers. 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
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 ACA2407 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. Pins11and14arebiasfeedsforinputampliers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.
The device may be operated safely over these conditions; however, parametric
performance is guaranteed only over the conditions defined in the electrical
specications.
