Combinations of supply voltage, supply current, input power, and output power shall not exceed PD. When operated at this bias condition with a base plate temperature of 85 C, the MTTF life is 2 E+8 hours. Junction operating temperature will directly affect the device median time to failure (TM). For maximum life, it is recommended that junction temperatures be maintained at the lowest possible levels. 2 TriQuint Semiconductor Texas Phone: (972)994-8465 Fax: (972)994 8504 Email: info-mmw@tqs.com Web: www.triquint.com Advance Product Information Aug 16, 2005 TGA2923-SG TABLE II RF CHARACTERIZATION TABLE (TA = 25qC, Nominal) (Vd = 8 V, Idq = 1.2 A) TEST CONDITION f = 3.5 GHz f = 3.5 GHz f = 3.5 GHz f = 3.5 GHz SYMBOL Gain IRL ORL Psat PARAMETER Small Signal Gain Input Return Loss Output Return Loss Saturated Output Power TYPICAL 9 12 15 40 UNITS dB dB dB dBm TABLE III THERMAL INFORMATION Parameter RJC Thermal Resistance (channel to backside of package) Test Conditions Vd = 8 V ID = 1.2 A Pdiss = 9.6 W TCH (oC) 162 RTJC (qC/W) 8 TM (HRS) 7.7 E+8 Note: Package backside was soldered to carrier at 85C baseplate temperature.

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.
