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 Oscillation will cease 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 ANSWER DOWNLOAD EXAMIANS APP
Microwave Communication The antenna separations (in meters) required for optimum operation of a space diversity system can be calculated from:where R = effective earth radius (m) and L = path length (m) S = λR/RL S = λR/L S = 3λR/L S = 2λR/L S = λR/RL S = λR/L S = 3λR/L S = 2λR/L ANSWER DOWNLOAD EXAMIANS APP
