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