1. mainline loss includes theoretical power loss at coupled port. 2. the user must provide adequate means of heat removal to limit the temperature of ground connections 2,3,6,7 to 85c, in order to ensure proper performance. at 25c ambient temperature this requires thermal resistance of the user's pc board heat sink to be 35c/w or less when the unit is driven at maximum specifed rf input power, 55w. at higher ambient temperature, with the same heat sink, input power in watts must not exceed 55w x (85c -t a m b i e n t ) 60c. freq.
