Abstract
The utility model relates to a miniaturized ultra-wideband coupler which comprises a single-stage micro-strip coupler wired directly on a printed circuit board, wherein a microwave amplifier is welded at a coupling end of the single-stage micro-strip coupler. According to the utility model, an original multi-stage coupler can be replaced and the volume of the coupler can be greatly reduced just by integrating the single-stage micro-strip coupler and the microwave amplifier. The miniaturized ultra-wideband coupler has the advantages of integration, small volume, good reliability, simple design and low cost, the performance indicators of the miniaturized ultra-wideband coupler meet the user requirements, and the miniaturized ultra-wideband coupler is applicable to a variety of microwave systems.
Description
Technical field
The utility model relates to microwave system integrated technology field, especially a kind of pocket super-broadband coupler.
Background technology
At present, in microwave system, coupler is a kind of widely used microwave device, along with the extensive use of coupler, its bandwidth is had higher requirement in recent years.Conventional ultra broadband coupler is passive device, and there are following all drawbacks in it: use multistage coupling to realize that volume is excessive; Design and difficulty of processing are large, expensive etc.
The utility model content
The purpose of this utility model be to provide a kind of cost low, effectively dwindle the pocket super-broadband coupler of coupler volume.
For achieving the above object, the utility model has adopted following technical scheme: a kind of pocket super-broadband coupler, comprise the single-stage microstrip coupler that directly connects up at printed circuit board (PCB), and weld microwave amplifier on its coupled end.
Described microwave amplifier adopts little band Surface Mount encapsulation.
Described single-stage microstrip coupler is comprised of first and second the little band that directly connects up at printed circuit board (PCB), the two ends of first little band are respectively little tape input end, little band output, one end of second little band is isolation end, and the other end is coupled end, welds microwave amplifier on the coupled end of second little band.
The coupled end of described single-stage microstrip coupler is as the input of microwave amplifier, and the output of microwave amplifier is as the output of ultra broadband coupler.
As shown from the above technical solution, the utility model only need adopt the integrated mode of single-stage microstrip coupler and microwave amplifier, just can substitute original multistage coupler, has greatly dwindled the volume of coupler.The utlity model has integrated small size, good reliability, simplicity of design, advantage that cost is low, performance index meet customer requirements, are applicable to multiple microwave system.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of pocket super-broadband coupler comprises the single-stage microstrip coupler 10 that directly connects up at printed circuit board (PCB) 30, the upper welding of its coupled end 12b microwave amplifier 20, and described microwave amplifier 20 adopts little band Surface Mount encapsulation, as shown in Figure 1.Single-stage microstrip coupler 10 directly is produced on the printed circuit board (PCB) 30, and microwave amplifier 20 is selected little band Surface Mount encapsulation, is positioned on the residing printed circuit board (PCB) 30 of single-stage microstrip coupler 10 coupled end 12b solder joint is set, and microwave amplifier 20 is welded on this solder joint.
As shown in Figure 1, described single-stage microstrip coupler 10 is by directly being with 11,12 to form in that first and second of printed circuit board (PCB) 30 wirings is little, first little two ends with 11 are respectively little tape input end 11a, little band output 11b, a second little end with 12 is isolation end 12a, the other end is coupled end 12b, the upper microwave amplifier 20 that welds of second little coupled end 12b with 12.The coupled end 12b of described single-stage microstrip coupler 10 is as the input of microwave amplifier 20, the output of microwave amplifier 20 utilizes the complementary characteristic between amplifier gain and the coupler coupling coefficient to realize the ultra broadband coupling as the output of ultra broadband coupler.
Single-stage microstrip coupler 10 in the utility model adopts single-stage arrowband couplers, can be easily carries out integratedly with microwave amplifier 20, and coupled end 12b carries out exporting after equilibrium amplified through microwave amplifier 20.
In a word, the utility model only need adopt the integrated mode of single-stage microstrip coupler 10 and microwave amplifier 20, just can substitute original multistage coupler, has greatly dwindled the volume of coupler.The utlity model has integrated small size, good reliability, simplicity of design, advantage that cost is low, performance index meet customer requirements, are applicable to multiple microwave system.
