摘要
A power-amplifier array based on a slotted-waveguide power divider is presented for quasi-optical applications. The advantages of this structure are its low profile and ease of Fabrication. Furthermore, efficient heat sinking of power devices is achieved. An X-band version of the power amplifier using eight MESFET's was designed and fabricated. An output power of 14 W was obtained. At 10 GHz, the amplifier gain and power-combining efficiency were 6.7 dB and 88%, respectively. The 3-dB bandwidth for the circuit was approximately 5%, This technique has the potential to meet the increasing demand for solid-state power amplifiers used in millimeter-wave communications and radar systems.
