Abstract :
A periodic second-harmonic spatial power combining oscillator is designed and fabricated. This circuit does not require an external resonator. It is planar, and therefore it makes the design of monolithic circuits easier. In this work, four X-band Gunn diodes are used. The effective radiated power is 370 mW at 18.6 GHz. The isotropic conversion efficiency is 10.2%.<>
