Thermal Considerations and Package Mounting: The rated power dissipation is only available when the package mounting surface is at 25°C and the junction tem- perature is 175°C. The thermal resistance between junc- tions and case mounting surface is 0.3°C/W. When instal- led, an additional thermal impedance of 0.1°C/W between the package base and the mounting surface is typical. In- sure that the mounting surface is smooth and flat. Thermal joint compound must be used to reduce the effects of small surface irregularities. Use the minimum amount necessary to coat the surface. The heatsink should incorporate a cop- per heat spreader to obtain best results. The package design clamps the ceramic base to the heatsink. A clamped joint maintains the required mounting pressure while allowing for thermal expansion of both the base and the heat sink. Four 4-40 (M3) screws provide the required mounting force. Torque the mounting screws to 6 in-lb (0.68 N-m). .330 .210.210 .375 .570ARF466FL 1.500 .100 .100 .300 .200 .005 .040 .320 1.250 .125R 4 pls .125dia 4 pls DS S SS G ARF466FL C6 R2 150V RF Output RF Input
