Microwave Communication A reflex klystron is oscillating at the frequency of its resonant cavity. If the reflector voltage is made slightly less negative, the Bunching would occur earlier in time Output power would increase The frequency will decrease Oscillation will cease Bunching would occur earlier in time Output power would increase The frequency will decrease Oscillation will cease ANSWER DOWNLOAD EXAMIANS APP
