Abstract

The invention relates to a technique for synthesizing ten paths of power space in a wave guide at the wave band Ku, which adopts two single-path and single-side fin line circuit amplifying boards and four double-path fin line circuit amplifying boards with different length and adopts the symmetrical placing mode of 1+2+2+2+2+1 to realize synthesis of ten paths of power space in a wave guide. The invention has the advantage of synthesizing ten paths of power space in a wave guide by six circuit boards, saves space, reduces volume of models and has the synthesizing efficiency of above 80%.

Description

technical field [0001] The invention relates to a space power combining technology, in particular to a 10-channel combining device for space power combining in a Ku-band waveguide. Background technique [0002] Nowadays, some military and commercial communication systems require higher and higher output power of high-power solid-state amplifiers. In order to obtain high-power output to meet the needs of these systems, the single power device based on semiconductor technology or vacuum microelectronics technology can be improved. The output power can also use power combining technology to superimpose the output power of multiple solid-state devices in phase to obtain the desired power output. However, from two aspects of cost and reliability, the power combining solid-state amplifier system has obvious advantages. Among the existing power combining categories, compared with chip-level and circuit-level power combining, the advantage of spatial power combining is that the siz...
