Abstract
The invention discloses a circulator. The circuit structure is achieved through three LC resonance units connected in series and three grounded capacitors. Three ports are distributed in the 120-degree direction, incident waves of any port are transmitted to the next port according to the certain direction and the certain sequence, and the functions such as signal transmission and signal isolation are completed. The circulator can be widely used in a wireless mobile communication system. The circulator is simple in structure, small in size, convenient to use and excellent in performance and brings convenience to circuit integration.
Description
Technical field
The invention belongs to circulator, particularly a kind of lumped element circulator circuit.Belong to electronics and communication field.
Background technology
In the last few years, carried out a series of research about circulator circuit both at home and abroad.In specific frequency range, get
Obtained 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; In the systems such as microwave communication, electronic countermeasures, microwave measurement, phased array radar assembly, there is important effect.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; Launching with receiving terminal as the buffer action of power amplifier, switching amplifier and the decoupling effect in measuring system etc., to reach the object of protection system, the raising stability of a system and reliability.
And traditional circulator circuit is due to the problem of its circuit structure, make temperature sensitivity extremely strongly, 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 object of the invention is to provide a kind of lump type components and parts to build, have belt effect, the lumped element circulator that simple in structure, volume is little, stability is high, temperature sensitivity is relatively little.
The technical scheme that realizes the object of the invention is: a kind of circulator, comprises three port ones (Port1), port 2(Port2) and port 3(Port3); Three series LC resonant elements, three ground capacities realize; Wherein each port is connected with a series LC resonant element, and the other end of three series LC resonant elements is connected in a bit jointly; Each electric capacity one end is connected with port, and the other end is connected to the ground and connects; Each port all connects 100 ohmages.Wherein three ports are pressed
direction distributes, and by the incident wave of arbitrary port, imports next port into according to certain orientation order, the function such as transmission and isolation of settling signal; Each device all adopts lamped element to realize.Its circuit structure can be realized signal and go in ring in 1KMz-10GHz frequency range.
Compared with prior art, form because the present invention adopts lump structural elements device fabrication, the remarkable advantage bringing is: (1) signal attenuation is less; (2) small volume; (3) out-of-band noise suppresses good; (4) good stability; (5) temperature-insensitive is strong; Applicable to various in the higher mobile communication system of performance requirement.
