Abstract

The present invention relates to a waveguide internal solid state push-pull amplified power synthesizer based on finline balun. It includes two open power synthesis modules, between said two open modules is assembled a closed waveguide formed from at least a H-shaped power synthesis module and a partial waveguide block, several pairs of push-pull MMIC of every module are directly welded and mounted on the heat sink, and the input and output graded slit-width finline balun arrays of several finline balun structures are three-D stereoscopically placed on the electric field directions of input and output waveguide sections, and the graded slit-width finline balun array and several pairs of MMIC using push-pull mode to work are adopted to implement power synthesis in closed waveguide. It has wide frequency band, high gain and ideal linearity, so that it can be substituted for high power electric vacuum device.

Description

technical field [0001] The invention relates to a high-power solid-state amplifier technology for microwave and millimeter-wave transmitting systems, in particular to a solid-state push-pull amplifying power combiner in a waveguide based on a fin-line balun structure. Background technique [0002] At present, the frequency of solid-state devices has been extended to hundreds of GHz, that is, the submillimeter wave band. In the microwave and millimeter wave bands, hybrid integrated circuits of single solid-state devices and monolithic microwave millimeter wave integrated circuits (MMICs) have been widely used, and low-noise and low-power electric vacuum devices (TWT & Klystron) have been completely replaced. [0003] However, in terms of high-power broadband, solid-state devices are still insufficient, and electric vacuum devices are still dominant. However, due to the advantages of solid-state devices such as small size, light weight, low voltage, high reliability, long lif...
