Abstract
The invention discloses a 26dB attenuation sheet with power of 1 watt. The attenuation sheet is formed by printing various sizing agents on an aluminum oxide substrate, the size of the aluminum oxide substrate is 2*3.5*0.635 millimeters, a back face of the aluminum oxide substrate is printed with a back guide layer, a front face of the aluminum oxide substrate is printed with guide lines and membrane-shaped resistors, the guide lines are connected with the membrane-shaped resistors to form a T-shaped attenuation circuit, the attenuation circuit is symmetric along a central line of the aluminum oxide substrate, an output end and an input end of the attenuation circuit are respectively connected with a pad, and the two pads are symmetric along the central line of the aluminum oxide substrate. On a scheme design, various performance indexes are fully considered, the attenuation sheet has high frequency and no induction, the situation that the attenuation sheet only can be originally applied to low frequency is broken through, the application requirement of the current three generation (3G) network can be met, and meanwhile, series product lines of a 1-watt fixed membrane-shaped resistance type attenuation sheet are expanded.
Description
Technical field
The present invention relates to a kind of aluminium oxide ceramics attenuator, particularly a kind of power is 1 watt 26dB attenuator.
Background technology
The attenuator of at present integrated three membranaceous resistive arrangement is widely used in apparatus field such as Aeronautics and Astronautics, radar, radio station, broadcast communication.The working load sheet can only merely consume the power of absorbing redundant; Analyze and use attenuator can also extract the signal that needs simultaneously at the power that absorbs reverse input; And on high-frequency circuit, adjust power level, and decouple, relevant device has been played protective effect.
Since more Zao with manufacturing abroad than domestic starting to the research and development of like product, the status of on product line still is product performance, all having the advantage.Existing attenuator attenuation accuracy is low on the domestic market simultaneously, and employable frequency range relative narrower.The attenuator that we hope is a power consumption component, can not be influential to two terminal circuits, that is to say, and all mate with two terminal circuits.When attenuation accuracy or VSWR do not reach when requiring, the signal that output obtains does not meet actual requirement.
Summary of the invention
Deficiency to above-mentioned prior art; The technical problem that the present invention will solve provides a kind of impedance and satisfies 50 ± 1.5 Ω; Is 26 ± 1dB in the 3G frequency range with interior attenuation accuracy, and standing wave requires input, output in 1.2, can satisfy 1 watt of 26dB attenuator of power aluminium oxide ceramic substrate of the application requirements of present 3G network; Replace external like product, and on characteristic, fill up the blank of home products.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of power is 1 watt 26dB attenuator; Its said attenuator prints various slurries by aluminum oxide substrate and forms; Said aluminum oxide substrate is of a size of 2*3.5*0.635MM, and the back up of said aluminum oxide substrate has back of the body conducting shell, and the front of said aluminum oxide substrate is printed with lead and membranaceous resistance; Said lead connects said membranaceous resistance and is connected to form T type attenuator circuit; Said attenuator circuit is along the center line symmetry of said aluminum oxide substrate, and the output of said attenuator circuit, input are connected with a pad respectively, and said two pads are along the center line symmetry of said aluminum oxide substrate.
Preferably, be printed with the high temperature resistance diaphragm on the said membranaceous resistance.
Preferably, said lead is formed by the high temperature silver slurry printing of anti-silver ion migration.
Technique scheme has following beneficial effect: this power is 1 watt 26dB attenuator, and anti-silver ion animal migration is good, and resistance value is stable, so the pad value precision is high.The symmetric figure resistive arrangement, electric performance stablity property is good.Frequency of utilization is wide, and volume is little, and cost is low, can be widely used in the production of microwave products such as apparatus field isolator, circulator such as Aeronautics and Astronautics, radar, radio station, broadcast communication.
Above-mentioned explanation only is the general introduction of technical scheme of the present invention, understands technological means of the present invention in order can more to know, and can implement according to the content of specification, below with preferred embodiment of the present invention and conjunction with figs. specify as after.Embodiment of the present invention is provided by following examples and accompanying drawing thereof in detail.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described in detail.
As shown in Figure 1; This power is the aluminum oxide substrate 1 that 1 watt 26dB attenuator comprises a 2*3.5*0.635MM; The back up of aluminum oxide substrate 1 has back of the body conducting shell, and the front of aluminum oxide substrate 1 is printed with lead 2 and membranaceous resistance R 1, R2, R3, and membranaceous resistance R 1, R2, R3 are connected to form attenuator circuit through lead; Attenuator circuit is electrically connected with back of the body conducting shell through the silver slurry, thereby makes the attenuator circuit earth-continuity.This attenuator circuit is along the center line symmetry of aluminum oxide substrate; Membranaceous resistance R 1, R2, the last high temperature resistance diaphragm 3 that is printed with of R3; The upper surface of lead 2 and high temperature resistance diaphragm 3 also is printed with one deck black protective film 4, can form protection to lead 2 and membranaceous resistance R 1, R2, R3 like this.
This power be 1 watt 26dB attenuator to require the impedance of input and ground connection be 50 ± 1.5 Ω, the impedance of output and ground is 50 ± 1.5 Ω.Signal input part gets into attenuator, through the progressively absorption to power of membranaceous resistance R 1, R3, R2, exports actual needed signal from output.
This power is 1 watt 26dB attenuator, and anti-silver ion animal migration is good, and resistance value is stable, so the pad value precision is high.The symmetric figure resistive arrangement, electric performance stablity property is good.Frequency of utilization is wide, and volume is little, and cost is low, can be widely used in the production of microwave products such as apparatus field isolator, circulator such as Aeronautics and Astronautics, radar, radio station, broadcast communication.
More than be that 1 watt 26dB attenuator has carried out detailed introduction to a kind of power that the embodiment of the invention provided; For one of ordinary skill in the art; According to the thought of the embodiment of the invention, the part that on embodiment and range of application, all can change, in sum; This description should not be construed as limitation of the present invention, and all any changes of making according to design philosophy of the present invention are all within protection scope of the present invention.
