It closes；
The inner sleeve and the pedestal press fit；The inner surface of inner race is that impedance converts section structure；
The pedestal and the outside of inner cover are socketed with radiator, the radiator and the inner sleeve and the pedestal close-fitting
Close connection；
The upper end of the resistance connects the connector by contact pin.
Preferably, the radiator is aluminium alloy, and the depth of 0.2-0.5um below the extexine of the radiator passes through electricity
Swimming oxide blacking generation has oxide layer.
Preferably, the resistance is beryllium oxide resistance slurry；Resistance includes being sintered by thick film circuit printing technology
High-frequency integrated circuit.
As it can be seen that ultra-wide band radio-frequency load proposed by the present invention, resistance and pedestal and inner surface of inner race tight fit connection, inner sleeve
Be connected with radiator with pedestal, thus the heat of resistance can be transferred to the pedestal and inner sleeve of its tight fit connection radiator into
Row heat dissipation, ensure that the heat dissipation of rf load, prevent resistance from burning because of heat accumulation.
Detailed description of the invention
Fig. 1 is the cross-sectional view for the ultra-wide band radio-frequency load that the embodiment of the present invention proposes；
Fig. 2 is the main view of the mounting hole for the ultra-wide band radio-frequency load that the embodiment of the present invention proposes.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
As depicted in figs. 1 and 2, the embodiment of the present invention proposes a kind of load of ultra-wide band radio-frequency, including connector 1, resistance 2,
Inner sleeve 3, pedestal 4 and radiator 5；
The pedestal 1 is provided with the mounting hole 6 of protrusion, the side wall setting fluted 7 of the mounting hole 6；
The lower end of the resistance 2 and 6 tight fit of mounting hole；The inner surface of the side of the resistance 2 and the inner sleeve 3
Tight fit；
The inner sleeve 3 and 4 press fit of pedestal；3 inner surface of inner sleeve is that impedance converts section structure；
Radiator 5, the radiator 5 and the inner sleeve 3 and the bottom are socketed with outside the pedestal 4 and the inner sleeve 3
4 tight fit connections of seat；
The upper end of the resistance 2 connects the connector by contact pin.
As it can be seen that the ultra-wide band radio-frequency load that the embodiment of the present invention proposes, resistance and pedestal and inner surface of inner race tight fit connect
It connects, inner sleeve and pedestal are connected with radiator, so that the heat of resistance can be transferred to the pedestal and inner sleeve of its tight fit connection
Radiator radiates, and ensure that the heat dissipation of rf load, prevents resistance from burning because of heat accumulation.
In a preferred embodiment of the invention, the radiator is aluminium alloy, below the extexine of the radiator
The depth of 0.2-0.5um has oxide layer by the generation of electrophoresis oxide blacking.
It is aoxidized by the appearance in cooling fin by electrophoresis and carries out blackening process, the antirust ability of cooling fin can be increased.
Meanwhile it can be in the depth shape of the extexine 0.2-0.5um once of radiator by electrophoresis oxide blacking
At one layer of fine and close oxide layer, come out to can more effectively be absorbed internal heat by oxide layer when radiating, in turn
It is dispersed into air.
In a preferred embodiment of the invention, the resistance is beryllium oxide resistance slurry；Resistance includes passing through thick film
High-frequency integrated circuit made of circuit printing processes sintering.
In the present embodiment, resistance material is the resistance slurry for using the NEW TYPE OF COMPOSITE of beryllium oxide, and is printed using thick film circuit
High-frequency integrated circuit made of the sintering of dataller's skill, so that resistance can satisfy the high frequency requirements of 10G.
As it can be seen that the wide band radio-frequency load that the embodiment of the present invention proposes, resistance material are the electricity with the NEW TYPE OF COMPOSITE of beryllium oxide
Resistance paste, and the high-frequency integrated circuit made of the sintering of thick film circuit printing technology, alternating-current resistance own frequency meet 10G
High frequency requirements；Alternating-current resistance is placed in pedestal, pedestal is with reeded mounting hole, since the side wall of mounting hole is equipped with recessed
Slot, the opening of groove extend to the top of mounting hole, so as to adapt to the slight change of resistance radius；It is to have outside resistance
The inner sleeve for having impedance step by step to convert, the inner sleeve are the structures come out by electromagnetic-field simulation, are designed using impedance transformation section,
The electromagnetic field that a transformation is formed around resistance, transmits electromagnetic wave smoothly around resistance, Jin Erneng
Amount can be fully absorbed and areflexia by resistance, meet the requirement of voltage standing wave ratio≤1.2；Inner sleeve and radiator pass through tight fit
Be attached, guarantee that heat can be all transferred to above radiator, thus guarantee resistance itself will not because heat gathers and
