Abstract
The invention discloses a four-stage band line cavity directional coupler and relates to the technical field of couplers. The four-stage band line cavity directional coupler comprises a housing, a coupling straight bar, a coupling curved bar, a resistor and a debugging block, wherein the coupling straight bar and the coupling curved bar are arranged in a cavity of the housing; the two ends of the coupling straight bar are connected with the outside through the housing; one end of the coupling curved bar is connected with the outside through the housing, and the other end of the coupling curved bar is connected with the resistor. The four-stage band line cavity directional coupler adopts a coupling band line four-stage design and can not only meet the requirements of an ordinary cylindrical coupler on the coverage bandwidth, but also reduce the processing requirement precision, the assembly requirements and the production cost in the production process.
Description
Technical field:
The present invention relates to coupler technologies field, particularly relate to a kind of air cavity band line coupler.
Background technology:
The frequency of now widely used cavity directional coupler is between 800-2500MHz, this frequency covers the main frequency of mobile communication, also contemplated the universal frequency of 3G simultaneously, due to popularizing of Digital Television, the frequency that original analog signal cancels 700MHz gradually is probably used on the product of 3G, if want entirely to be with covering, just need the coupler that bandwidth is wider, power splitter, more frequency range can be covered like this, existing coupler generally adopts column Coupling Design, although can more frequency range be covered, but because its production cost is high, machining accuracy is high, the shortcomings such as matching requirements are high, significantly limit the application of this series products.
Summary of the invention:
The object of this invention is to provide a kind of level Four band line cavity directional coupler, it have employed the design of coupled striplines level Four, not only can meet general column coupler for covering the requirement of bandwidth, and the processing request precision reduced in production process and matching requirements and production cost.
In order to solve the problem existing for background technology, the present invention is by the following technical solutions: it is made up of shell, the straight rod of coupling, coupling curved rod, resistance, debugging block, the straight rod of coupling, coupling curved rod is provided with in described enclosure cavity, the two ends of the straight rod of coupling are all connected with outside by shell, one end of coupling curved rod is connected with outside by shell, the other end is connected with resistance, respectively respectively in the straight rod of described coupling, coupling curved rod arranges a debugging block.
The straight rod of described coupling, coupling curved rod are made up of one-level coupled zone, secondary coupled zone, three grade coupled districts, quadrupole district respectively.
Described debugging block is separately positioned on the front end in three grade coupled districts of the straight rod of coupling, coupling curved rod, the immediately position of secondary coupled zone.
Described debugging block cross section is rectangle, and it is long and wide can choose arbitrarily between 1.5 × 1.5mm to 2 × 2mm.
The present invention is provided with the straight rod of coupling in enclosure cavity, coupling curved rod, the straight rod of coupling, coupling curved rod is respectively by one-level coupled zone, secondary coupled zone, three grade coupled districts, quadrupole district is formed, one end, one-level coupled zone of the straight rod of coupling is output, one end, quadrupole district is input, one end, one-level coupled zone contact resistance of coupling curved rod, for isolation end, one end, quadrupole district is coupled end, microwave signal inputs from input, part signal exports from output, produce coupled wave in coupling curved rod simultaneously, another part microwave signal just exports from coupled end, this completes the allocating task of power, because the straight rod of coupling, coupling curved rod adopts the design of air cavity level Four band line, make the bandwidth of coupler wider, 350-2700MHz can be covered, simultaneously at the straight rod of coupling, coupling curved rod on respectively each arrange one debugging block, choose suitable dimension, the isolation effect of coupler can be made better, standing wave change is little, the fluctuation range of the degree of coupling also diminishes, thus reduce its processing request precision in process of production, matching requirements and production cost.
Present invention employs the design of coupled striplines level Four, not only can meeting general column coupler for covering the requirement of bandwidth, and the processing request precision reduced in production process and matching requirements and production cost.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
