Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, other drawings may also be obtained based on these drawings.
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
In order to make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
Referring to Fig. 1,800 watts of high-power resistors provided by the utility model comprising bottom plate 100, oxidation beo substrate 200,
Grounding electrode 300, silver electrode 400, resistive film 500 and lead 600.
The back side for aoxidizing beo substrate 200 is equipped with roasting silver 210, and oxidation beo substrate 200 is connect by roasting silver 210 with bottom plate 100,
Bottom plate 100 is the heat dissipation area for increasing the application, to improve heat dissipation effect.
Grounding electrode 300, silver electrode 400 and resistive film 500 are separately positioned on the front of oxidation beo substrate 200, and electricity
Resistance film 500 can form distributed attenuation network structure by being connect with grounding electrode 300 and silver electrode 400, and the distribution declines
Subtracting network structure can be connected to by roasting silver 210 with bottom plate 100, so as to make entire attenuator circuit earth-continuity.
Lead 600 is connect with oxidation beo substrate 200, is for external signal to be imported into oxidation beo substrate 200
On, external signal first passes through gradually absorption of the resistive film 500 to power, so after lead 600 enters in oxidation beo substrate 200
Whole power are absorbed by 210 connection bottom plate 100 of roasting silver from grounding electrode 300 afterwards and are consumed by radiating mode.
In addition, being extended with inductance compensation line in the input electrode of lead 600, standing wave can be reduced by inductance compensation line
Than.
Resistive film 500 in the application is specifically made using vacuum sputtering tantalum nitride thick-film technique.
In addition, resistive film 500 is specially thermal oxide resistance trimming structure, the impedance of its input terminal and ground terminal is enabled in this way
All it is 100 ± 5 Ω.
Oxidation beo substrate 200 is specifically located at the intermediate position of bottom plate 100, and it is generally symmetrical to aoxidize beo substrate 200
Structure, grounding electrode 300 and resistive film 500 are located on the antimere of 200 side of oxidation beo substrate, and silver electrode 400 is arranged
At the intermediate position of oxidation beo substrate 200, so that the efficiency of entire attenuator circuit reaches maximum.
By the setting of above structure, the power capacity of parent itself may make to reach 800W, and it is small, have it is good fast
The heat-sinking capability of speed, stability is good, reproducible, can be widely applied to the equipment such as Aeronautics and Astronautics, radar, radio station, broadcast communication
Field.
