The structure is simple, the size is small, usage is convenient, performance is good and circuit integration is easy.
Description
Technical field
The invention belongs to circulating device, particularly a kind of lumped element circulator device.
Background technology
In the last few years, a series of research about circulator device had been carried out both at home and abroad.In specific frequency range, achieve many achievements, be especially used in WCDMA technology.Circulator is a kind of nonreciprocal many easily mouthpart parts, has along specific direction signal transmission, and the characteristic of opposite direction isolation signals; Important effect is had in the systems such as microwave communication, electronic countermeasures, microwave measurement, phased array radar assembly.As in the base station and mobile system of mobile communication, the common apparatus that circulator is connected with antenna as sending and receiving circuit; At launching and receiving end as the buffer action of power amplifier, switching amplifier and the decoupling effect in measuring system etc., to reach protection system, to improve the object of the stability of a system and reliability.
And traditional circulator device is due to the problem of its circuit structure, make temperature sensitivity extremely strong, applicability is very limited.The present invention is directed to above problem, can effectively solve, to meet system requirements, and stability is high, volume is little, processing is simple, applied widely.
Summary of the invention
The circulating device that the object of the invention is to provide a kind of lump type components and parts to build, has belt effect, structure is simple, volume is little, stability is high, temperature sensitivity is relatively little.
The technical scheme realizing the object of the invention is: a kind of circulating device, comprises three port ones (Port1), port 2(Port2) and port 3(Port3); This circuit structure, by the incident wave of arbitrary port, imports next port into according to certain orientation order.Its feature comprises: port one (Port1) is connected with node 1; Port 2(Port2) be connected with node 2; Port 3(Port3) be connected with node 3; L1C1 parallel resonator unit one end is connected with node 1, and the other end is connected with node 4; L2C2 parallel resonator unit one end is connected with node 2, and the other end is connected with node 4; L3C3 parallel resonator unit one end is connected with node 3, and the other end is connected with node 4; One end of electric capacity C is connected with node 4, and the other end is connected to the ground and connects; Each port all connects 50 ohmages.Each device all adopts lamped element to realize.Its circuit structure can realize signal and go in ring in 1KMz-10GHz frequency range.
Compared with prior art, because the present invention adopts lump structural components to process, the remarkable advantage brought is: (1) signal attenuation is less; (2) small volume; (3) out-of-band noise suppresses good; (4) good stability; (5) temperature-insensitive is strong; Be applicable in the various mobile communication system higher to performance requirement.
