1. Mainline loss includes theoretical power loss at coupled port.
Outline Drawing
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 35°C/W or less when
the unit is driven at maximum specified RF input power, 55W. At higher ambient temperature, with the same heat sink, input power in watts
must not exceed 55W x (85°C -Tambient) ÷ 60°C.
