Data corresponds to the typical application circuit and component values shown on page 3 of this datasheet. Parameters shown at nominal I = 290 mA unless otherwise noted. I is the total DC current draw from the V supply. As shown on page 3, it is distributed to CC CC CC pins 9 and 12 by balun T2 and pins 10 and 11 directly. Resistor R2 determines the DC voltage of A and thereby I at approximately BIASA/B CC 0.25 mA/. See page 5 for a typical I vs. R2 relationship assuming V = 5 V. CC CC 7,8 Absolute Maximum Ratings Handling Procedures Please observe the following precautions to avoid Parameter Absolute Maximum damage: Input Power 11 dBm V 6 V CC Static Sensitivity 9,10 Junction Temperature +150C Gallium Arsenide Integrated Circuits are sensitive to electrostatic discharge (ESD) and can be Operating Temperature -40C to +85C damaged by static electricity. Proper ESD control Storage Temperature -65C to +125C techniques should be used when handling these devices. 7. Exceeding any one or a combination of these limits may cause permanent damage to this device. 8. MACOM does not recommend sustained operation near these survivability limits. 9. Operating at nominal conditions with T 150C will ensure J 6 MTTF > 1 x 10 hours. 10.Junction Temperature (T ) = T + jc * (V * I) J C Typical thermal resistance ( jc) = 15 C/W. a) For T = +25C, T = 47C 5 V, 290 mA C J 22 b) For T = +85C, T = 107C 5 V, 290 mA 2 C J M/A-COM Technology Solutions Inc.
