Abstract :
In this paper, a Ka-band combining power amplifier based on SIW/HMSIW technology is presented and studied. The advantages of this structure are its low profile, low-lost, mass-productive, ease of fabrication and fully integrated with planar circuits. In addition, efficient heat sinking of monolithic microwave integrated circuit (MMIC) devices is achieved. Lastly a SIW/HMSIW power amplifier using eight MMIC amplifiers was designed and fabricated in 33.5-35.5 GHz. The measured results show a good agreement with simulation and a combining efficiency of 72% is achieved at 34.3 GHz.
