Abstract: A microwave electrothermal thruster (MET) and its control system is disclosed and claimed. The MET control system uses a dielectric resonator oscillator (DRO) in series with a GaN MMIC-based Solid State Power Amplifier (SSPA) to generate microwave energy, transfer it to a thrust chamber, and heat a propellant that exits a nozzle, providing thrust. The control system uses feedback to provide autonomous control of the MET. A wide variety of propellants may be used, including, for example, hydrazine, ammonia, and water.
