PRODUCT DESCRIPTION
The ACA2404 is a highly linear, high output power,
monolithic GaAs RF amplifier that has been
developed to replace standard CATV hybrid
amplifiers, in new designs. 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 ACA2404 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 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.
The device may be operated safely over these conditions; however, parametric
performance is guaranteed only over the conditions defined in the electrical
specifications.

Notes:
(1) N connector center pin should be approximately 80 mils in length.
(2) T1, T2 balun: 6.5 turns thru, as shown in Figure 15.
(3) Due to the power dissapation of this device, the printed circuit board should be mounted / attached to a heat sink.
(4) 400 mA minimum current rating.
