ly 2 Watts, if desired, to reach the 20-Watt output level. This will be described in detail later. Three VN67AF VMOS FETs are used in parallel to generate the 20 Watts of rf power Each FET supplies about 1 3 of the total power. Because of the VMOS's built-in zener diode, CR1 has been added to the circuit, It clips the input sine-wave signal so that it does not go negative. If CR1 was not in the circuit, the FET would quickly be destroyed. There is no forward bias used on the FETs and thus the...
