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.

1 Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other parameters set at
or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device.
2 Pins 2, 4, 5, and 7 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.
This device must be protected at all times from ESD when handling or transporting. Static charges may easily produce
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.

Package and Handling Information
The PCB layout footprint drawing for the ACA1216 is shown in
Figure 4. The package dimensions for the ACA1216 are shown in
Figure 5. The tape and reel dimensions are provided in Figure 6.
Since the device package is sensitive to moisture absorption, it is
baked and vacuum packed before shipping. Instructions on the
shipping container label regarding exposure to moisture after the
container seal is broken must be followed. Otherwise, problems
related to moisture absorption may occur when the part is
subjected to high temperature during solder assembly.
The ACA1216 is rated to Moisture Sensitivity Level 2 (MSL2) at
260 C. It can be used for lead or lead-free soldering. For
additional information, refer to the Skyworks Application Note,
Solder Reflow Information, document number 200164.
Care must be taken when attaching this product, whether it is
done manually or in a production solder reflow environment.
Production quantities of this product are shipped in a standard
tape and reel format.
