Recommended operating conditions are specified in Table 3, and electrical specifications are provided in Table 4. Table 2. ACA1212 Absolute Maximum Ratings1 Parameter Minimum Maximum Units Amplifier supplies (pins 11 and 14) 0 +15 VDC RF input power (pins 3 and 6) - +70 dBmV Storage temperature –6 5 +150 °C Soldering temperature - +260 °C Soldering time - 5.0 sec 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 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. 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. Table 3.

The package dimensions for the ACA1212 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 ACA1212 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.
