Abstract
The utility model provides an absorption load with a broadband resistance conversion unit. The absorption load comprises at least one broadband impedance converter, at least one terminal load sheet, an aluminium alloy upper cover plate and an aluminium alloy pedestal. The broadband impedance converter is embedded into the center of the aluminium alloy pedestal and is connected with the terminal load sheet. The absorption load exhibits good application effects, and helps to solve problems that a conventional load is high in price and is liable to be burnt.
Description
Technical field
The utility model relates to a kind of absorbing load, relates in particular to a kind of absorbing load with resistance conversion unit, broadband.
Background technology
Absorbing load is used for absorbing unwanted power, or when system is in non-equilibrium state, comes the assurance system in running order by absorption portion power.
In radio and television emissions antenna transmission system, the absorbing load equipment that is absolutely necessary.The existing load great majority of using are therein formed in succession by a plurality of chip attenuators, and chip attenuator cost is high, and heat dispersion is general, and are therefore high by the load price of its production and burn easily.
The utility model content
The purpose of this utility model provides a kind of high-power absorbing load that is comprised of the high terminate load sheet of cost performance, and it can solve the problem that load price in the prior art is high and burn easily, and effect is good.
The utility model provides a kind of absorbing load with resistance conversion unit, broadband, and described absorbing load comprises at least one broadband impedance transformer, at least one terminate load sheet, aluminium alloy upper cover plate and aluminum alloy base; Described broadband impedance transformer is embedded into the centre of described aluminum alloy base and is connected with described terminate load sheet.
Preferably, described broadband impedance transformer is the red copper broadband impedance transformer of gradual change height.
Preferably, described aluminum alloy base has the curve elongated slot of one fixed width even depth.
Preferably, described terminate load sheet is a plurality of and parallel with one another.
Preferably, the resistance value of described absorbing load sheet is 50 ohm.
Absorbing load with resistance conversion unit, broadband of the present utility model also comprises input interface and fin; Described input interface is connected with described broadband impedance transformer and/or described terminate load sheet, and described fin is fixed on the metallic object outside that is comprised of upper cover plate and base by heat-conducting silicone grease and stay bolt.
The advantage of described absorbing load of the present utility model is: use the terminate load sheet to replace the chip attenuator, cost performance is high, and perfect heat-dissipating is difficult for burning.
Description of drawings
Fig. 1 is schematic diagram of the present utility model.
Description of reference numerals is as follows:
Aluminium alloy upper cover plate 1, impedance transformer 2, terminate load sheet 3, aluminum alloy base 4.
Embodiment
For making the auditor can further understand structure of the present utility model, feature and other purposes, now being accompanied by accompanying drawing in conjunction with appended preferred embodiment is described in detail as follows, the illustrated embodiment of this accompanying drawing only is used for the explanation the technical solution of the utility model, and non-limiting the utility model.
See also schematic diagram of the present utility model, Figure 1 shows that the absorbing load with resistance conversion unit, broadband, described absorbing load comprises aluminium alloy upper cover plate 1, broadband impedance transformer 2, terminate load sheet 3, aluminum alloy base 4, and broadband impedance transformer 2 is connected connection with the terminate load sheet.Wherein, broadband impedance transformer 2 is the red copper broadband impedance transformer of gradual change height.Broadband impedance transformer 2 is embedded into the centre of aluminum alloy base 4 and is connected with terminate load sheet 3.The curve elongated slot that processing has the one fixed width even depth on the aluminum alloy base 4.Terminate load sheet 3 is 2, and is in parallel between 2 terminate load sheets.The equivalent resistance of impedance transformer 2 after with terminate load sheet 3 parallel connections that connect later is transformed into 50 ohm, and sets the lower limit of described absorbing load operating frequency by the length of regulating this impedance transformer.
Described absorbing load of the present utility model can also comprise the input interface of standard and the fin of suitable size.Wherein, the standard input interface is connected with described broadband impedance transformer 2 and/or described terminate load sheet 3, and aluminum alloy base 4 is connected with fin.Thus, absorbing load described in the utility model can realize good radiating effect, is difficult for being burnt, long service life, and the characteristic impedance of its impedance and feeder line is close to and equates, can be connected with the device such as antenna transmission system, brings into play the effect of its high-power absorbing load.
What need statement is that above-mentioned utility model content and embodiment are intended to prove the practical application of technical scheme that the utility model provides, and should not be construed as the restriction to the utility model protection range.Those skilled in the art are in spirit of the present utility model and principle, when doing various modifications, being equal to and replacing or improve.Protection range of the present utility model is as the criterion with appended claims.
