Operating at nominal conditions with TJ < 155C will ensure MTTF > 1 x 106 hours. 9. Assumes maximum gain state. For each dB of attenuation the maximum RF Input Power may increase by 1 dB up to +7 dBm. 10. Junction Temperature (TJ) = TC + JC * (V * I) Typical thermal resistance (JC) = 14.6C/W. a) For TC = 25C, TJ = 71 C @ 6 V, 520 mA (Stage3, ID3 ) b) For TC = 100C, TJ = 141 C @ 6 V, 470 mA (Stage3, ID3 ) Printed Circuit Board (PCB) Thermal Design 11. Assumes maximum gain state, for each dB of attenuation the maximum RF input power may increase by 1 dB up to +10 dBm. 12. Exceeding any one or combination of these limits may cause permanent damage to this device. 13. MACOM does not recommend sustained operation near these survivability limits. Handling Procedures Please observe the following precautions to avoid damage: Static Sensitivity Integrated Circuits are sensitive to electrostatic discharge (ESD) and can be damaged by static electricity. Proper ESD control techniques should be used when handling these devices. To maintain reliable junction temperatures for this high power amplifier the printed circuit board must provide low thermal resistance to the exposed paddle of the IC package. This requires both a large array of high thermal conductive vias beneath the IC as well as good heat sinking at the back of side of the PCB. In general, thinner substrates and thicker plating for vias provide lower thermal resistance. For a standard 62 mil board the following copper plating thickness for vias and top and bottom metal layers are recommended. Vias plated to 2-mil (50 m) thickness of copper. Finished via diameter 9.5 mils (0.25 mm). Via spacing 20 mils (0.51 mm). 2.8-mil (70 m) thick copper for top and bottom metal.
