Abstract
The utility model discloses a high-power microwave power combiner module, aiming to provide a microwave power combiner module, which has high power capacity, small volume and high reliability. The high-power microwave power combiner module comprises a cylindrical metal shielding cavity, wherein an output microwave coupling probe is positioned at the center of the shielding cavity; and input microwave coupling probes, encircling the output microwave coupling probe and fixedly linked with an external connector of the shielding cavity, are arranged at the periphery of the shielding cavity. In the utility model, the metal microwave coupling probes capable of bearing high power are integrally processed and molded with the connector, so that high-capacity microwave power combination is realized, and the problems such as low power capacity and large volume in the present microwave power combiner adopting a micro-strip structure are solved.
Description
Technical field
The utility model relates to a kind of High-Power Microwave power combiner module.
Background technology
At present, microwave power synthesizer generally is to use Wilkinson merit branch/blending theory, and little band theory is the microstrip line form microwave power mixer of basic engineering.
The factor of the power capacity of decision microwave power mixer microstrip circuit is more, as the dielectric constant of substrate, thickness, the coefficient of heat conduction, and the material of the thickness of copper-clad, adhesive force, overlay coating etc.When now selecting with the substrate of mixer, above parameter is conventional value (dielectric constant 2.55, thickness 1.5mm, 2 pounds of adhesive force, overlay coating are nickel).Because microwave power mixer not emphasis is considered the power capacity problem, causes the power capacity of mixer to be subject to baseplate material.In addition, the microwave power mixer has the conversion of coaxial connector and little band at high-power output position.Because the existence of microstrip circuit Insertion Loss, and the difference of coaxial microband transfer point welding and assembling technics, surpass 1000W for a long time in transmission signal strength, especially when the part heat radiation can't guarantee, the fusion of output coaxial microband transfer point meeting occurrence temperature causes exporting standing wave and worsens reflection enhancement, aggravation microstrip line temperature rises, and burns until microstrip line.
When little band power combiner designed, because the input way is more, and in order to improve power capacity, volume was all very big.
Summary of the invention
Low for overcoming the microstrip line power capacity, bulky the problems referred to above.The utility model provides a kind of power capacity height, and volume is little, the microwave power synthesizer module of the brand-new form that reliability is high.
The concrete technical scheme that the utility model adopted is: a kind of High-Power Microwave power combiner module, comprise, a cylindrical metal shielding cavity, it is characterized in that, in the central authorities of described shielding cavity, be provided with an output microwave coupling probe that is in the cavity center, around described shielding cavity, be periphery around this output microwave coupling probe, and the input microwave coupling probe that connects firmly with the shielding cavity aerial lug.
The beneficial effects of the utility model are:
The utility model is changed the pattern that tradition is used microstrip line design power synthesizer, an output microwave coupling probe is positioned over the cavity center, eight input microwave coupling probes are evenly distributed on the cavity inner periphery, reach the synthetic effect of microwave power, have reduced the volume of microwave power synthesizer.Adopt high-power metal microwave coupling probe, and probe and the whole processing of input and output connector, having improved power capacity, form is simple, the reliability height, cost is lower.
