PRODUCT DESCRIPTION
The ACA2407E 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 870 MHz CATV downstream
band is formed when one ACA2407E 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.
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.
The device may be operated safely over these conditions; however, parametric
performance is guaranteed only over the conditions defined in the electrical
specications.
