10.1.6 Temperature Protection
The temperature protection circuitry will protect the unit against over-temperature condi-
tions by reducing the output power. The reduction will start at 71 °C. At 81 °C, the power will
be reduced to 50% and at 85 °C to around 6%.
10.1.7 VSWR Protection
The VSWR protection circuitry will protect the unit against high VSWR conditions by reduc-
ing the output power. This protection will reduce the output power to 50% when the reverse
power is 10% of the forward power.
