Abstract: In order to investigate parameters and design methods of SAW stabilized microwave generators a methodology is elaborated. The generator is divided into four different blocks: SAW resonator, power divider, attenuator, and amplifier. This solution allows each block to be measured and analyzed separately. The amplitude and phase condition for generation can be calculated and the resonant frequency of the oscillator can be predicted. The measurements of the microwave oscillator are done in time and frequency domain by frequency meter and spectrum analyzer. The jitter and the spectrum are ob
