Summary:The design of the 330 GHz continuous-wave clinotron oscillator with the modified circuit is presented together with the simulation results of the cold cavity including the circuit coupled to the power output. The simulations revealed the effective broadband conversion of the surface wave excited by the sheet electron beam moving above the grating to the TE10 mode of the oversized output waveguide. The experimental studies of the clinotron oscillator demonstrated the operating frequency range from 280 to 335 GHz and the output power up to 110 mW. Finally, both simulation and experimental results revealed the excitation of the surface wave with one node of E-component along the grating lamella width that effectively transfers to TE20 mode of the waveguide output.
