Description

The ACA1216 surface-mount GaAs RF linear amplifier has been developed to provide a high-gain output stage for HFC/FTTC node and ORM RF amplifiers that require highest bit delivery efficiency, low power consumption, and a ultra-small landed product footprint. The MMIC consists of two parallel amplifiers, operating from a 12 volt power supply, forming the industry’s lowest cost per bit delivered power doubler (PD). The balanced amplifier approach is optimized for exceptionally low distortion and noise figure, while providing flat gain and excellent input/output return loss. The ACA1216 is designed as a single amplifier with similar total gain and output power as the combination of ACA1206 and ACA0862 or DOCSIS 3.1 compliant ACA1210 and ACA1216. ACA1216 provides a lower power dissipation solution than discrete amplifier cascades while providing better performance, error-free content delivery to 68 dBmV total composite power, smaller landed footprint, and lower BOM cost. A block diagram of the ACA1216 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.
