Abstract
The invention discloses an aluminum oxide ceramic substrate attenuation sheet with power of 1watt (W) and attenuation accuracy of 6dB. The aluminum oxide ceramic substrate attenuation sheet comprises an aluminum oxide substrate of which the size is 2*3.5*0.635mm, wherein a back guide layer is printed on the back side of the aluminum oxide substrate; a wire and film resistors are printed on the front side of the aluminum oxide substrate; the wire is connected with the film resistors to form an attenuation circuit; and the output end and the input end of the attenuation circuit are respectively connected with two bonding pads which are symmetrical about a central line of the aluminum oxide substrate. By utilizing the attenuation sheet, various performance indexes are fully considered in the scheme design, so that the attenuation sheet with the power of 1W can meet the application requirement of a third generation (3G) network at present; and meanwhile, the series production lines of fixed film resistor attenuation sheets with the power of 1W can be extended.
Description
Technical field
The present invention relates to a kind of aluminium oxide ceramics attenuator, the attenuator of 1 watt of 6dB of particularly a kind of aluminium oxide ceramic substrate.
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 6 ± 0.5dB in the 3G frequency range with interior attenuation accuracy, and standing wave requires input, output in 1.2, can satisfy 1 watt of 6dB attenuator of 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:
1 watt of 6dB attenuator of a kind of aluminium oxide ceramic substrate; It comprises that one is of a size of the aluminum oxide substrate of 2*3.5*0.635MM; The back up of said aluminum oxide substrate has back of the body conducting shell; The front of said aluminum oxide substrate is printed with lead and membranaceous resistance, and said lead connects said membranaceous resistance and is connected to form attenuator circuit, and said attenuator circuit is along the center line symmetry of said aluminum oxide substrate.
Preferably, said back of the body conducting shell and lead are formed by the conductive silver paste printing, and said resistance is formed by the resistance slurry printing.
Preferably, the upper surface of said lead and glass protection film also is printed with one deck black protective film.
Preferably, said circuit adopts T type attenuator circuit.
Technique scheme has following beneficial effect: 1 watt of 6dB attenuator of this aluminium oxide ceramic substrate is in a state of symmetry fully by attenuator circuit; This small product size is little; Frequency characteristic is good; The stability of circuit gets a promotion, and has broken the situation that original attenuator can only be applied to low frequency, makes attenuator can be applied to the network of 2G-3G.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; 1 watt of 6dB attenuator of this aluminium oxide ceramic substrate comprises the aluminum oxide substrate 1 of 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 glass protection film 3 that is printed with of R3; The upper surface of lead 2 and glass protection film 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.
It is 50 ± 1.5 Ω that 1 watt of 6dB attenuator of this aluminium oxide ceramic substrate requires the impedance of input and ground connection, and 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.
As substrate, this small product size is little with the aluminum oxide substrate that is of a size of 2*3.5*0.635MM for 1 watt of 6dB attenuator of this aluminium oxide ceramic substrate, and frequency characteristic is good; The stability of circuit gets a promotion; Broken the situation that original attenuator can only be applied to low frequency, special design simultaneously lets attenuator circuit be in a state of symmetry fully, makes the stability of circuit get a promotion; Broken the situation that original attenuator can only be applied to low frequency, made it can be applied to the network of 2G-3G.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 1 watt of 6dB attenuator of a kind of aluminium oxide ceramic substrate that the embodiment of the invention provided has been carried out detailed introduction; 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.
