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 Oscillation will cease The frequency will decrease Bunching would occur earlier in time Output power would increase Oscillation will cease The frequency will decrease ANSWER DOWNLOAD EXAMIANS APP
