Description

The ACA1212 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 cascaded between transmission line baluns that are optimized for exceptionally low distortion, high output power, and high crash point in a thermally enhanced surface-mount package. The ACA1212 covers the full 50 to 1218 MHz CATV downstream band demanded by DOCSIS 3.1 systems. A block diagram of the ACA1212 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. RF Input RF Output12 dB 12 dB 204202-001 Figure 1.

Table 2. Recommended operating conditions are specified in Table 3, and electrical specifications are provided in Table 4. Table 2. ACA1212 Absolute Maximum Ratings1 or below their nominal value. Exceedi ng any of the limits listed here may result in permanent damage to the device. 2 Pins 3 and 6 should be AC-coupled. No external DC bias should be applied. ESD HANDLING: Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device. potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD handling precautions should be used at all times. Table 3. ACA1212 Recommended Operating Conditions1 1 Performance is guaranteed only under the conditions listed in this table. Table 4. ACA1212 Electrical Specifications1 1 Measured with a balun on input and output of the device. See Figure 3 for test setup. 2 Device measured with 79 analog channels, +47 dBmV output power at 1000 MHz with a 3 dB tilt and QAM to 1000 MHz.
