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 85°C, in order to ensure

proper performance. At 25°C ambient temperature this requires thermal resistance of the user's PC board heat sink to be 27°C/W or less when

the unit is driven at maximum specified RF input power, 10W. At higher ambient temperature, with the same heat sink, input power in watts

÷ 60°C.
