Abstract :
Staggered double vane structure was used as the slow wave circuit and sheet beam was applied to design a 140GHz backward wave oscillator. A transition structure for the circuit was proposed to minimize the attenuation and reflection of the system. Numerical calculation results demonstrated that the oscillator can produce the average output power in excess of 1 watt ranging from 134-146GHz with the beam current of 10mA and accelerating voltage around 20kV. Such design offers the microwave community a promising solution for short-millimeter wave radiation source.
