Description

The ACA2429 is a highly linear, high-output power integrated RF

amplifier designed for CATV head-ends and HFC distribution

systems. The IC consists of two parallel amplifiers that are

optimized for exceptionally low distortion, high-output power, and

high crash-point in a thermally enhanced surface-mount package.

A GaN output stage is incorporated to minimize the operating

(bias) current, thus making this an excellent choice for

environmentally friendly "green" initiatives. The ACA2429

provides high gain over the 50 to 1218 MHz CATV downstream

band, and is cascaded between two transmission line baluns.

A block diagram of the ACA2429 is shown in Figure 1. The device

package and pinout are shown in Figure 2. Signal pin

assignments and functional pin descriptions are described in

Table 1.
