These ratings represent the maximum operable values for this device Combinations of supply voltage, supply current, input power, and output power shall not exceed PD at a package base temperature of 70C When operated at this bias condition with a baseplate temperature of 70C, the MTTF is reduced from 4.8E+6 to 1.0E+6 hours Junction operating temperature will directly affect the device median time to failure (MTTF). For maximum life, it is recommended that junction temperatures be maintained at the lowest possible levels.

Recommended Surface Mount Package Assembly
Proper ESD precautions must be followed while handling packages. Clean the board with acetone. Rinse with alcohol. Allow the circuit to fully dry. TriQuint recommends using a conductive solder paste for attachment. Follow solder paste and reflow oven vendors' recommendations when developing a solder reflow profile. Typical solder reflow profiles are listed in the table below. Hand soldering is not recommended. Solder paste can be applied using a stencil printer or dot placement. The volume of solder paste depends on PCB and component layout and should be well controlled to ensure consistent mechanical and electrical performance. Clean the assembly with alcohol.
