SOAR f = 175 MHz Th = 70 C Rth mb-h = 0,45 K/W VCCnom = 13,5 V PS = PSnom at VCCnom = 13,5 V and VSWR = 1 The transistor has been developed for use with unstabilized supply voltages. As the output power and drive power increase with the supply voltage, the nominal output power must be derated in accordance with the graph for safe operation at supply voltages other than the nominal. The graph shows the permissible output power under nominal conditions (VSWR = 1), as a function of the expected supply over-voltage ratio with VSWR as parameter. The graph applies to the situation in which the drive (PS/PSnom) increases linearly with supply over-voltage ratio.
