A side appending three-cavity transmit time oscillator is proposed. Through 1-D single particle theory, the effects of the direct current transit angle and the volt modulating coefficient on the microwave power conversion efficiency are analysed. Numerical simulation is done to verify the theoretical analysis results. Numerical simulation indicates that the foilless oscillator can output an average power of 8 GW at 3.9 GHz when excited by a 400 keV, 60 kA radial electron beam, with an impedance of 6.7 n.
