Technical field

One embodiment of the invention is related to a kind of non-reciprocal circuit element (Non-reciprocal circuit Element), the performance of (tuning) isolator (isolator) can more easily be tuned.

Background technique

In recent years, with the increase of wireless communication needs and the development of the communication technology, the demand to communication equipment is continuous Increase, price competition is also growing more intense.

As a result, the case where improving the productivity of communication equipment, reducing cost, requirement increase to the miniaturization of system Under, the requirement to the miniaturization of such as circulator (circulator) or isolator non-reciprocal circuit element for communication equipment Increasingly increase.

Circulator (Circulator) or isolator (Isolator) as microwave or light wave transmitting circuit have can be to The direction transmission electromagnetic wave of transmission line, and the characteristic that the transmission to the electromagnetic wave of opposite direction is blocked, therefore be referred to as Non-reciprocal circuit element (Non-reciprocal Circuit Element).

This irreversible transmitting circuit element (Non-reciprocal Circuit Element) is used as high-frequency communication portion Part, be typically set to by the signal of the input of port (port) as defined according to Faraday rotation (Faraday Rotation) to Defined direction rotates, and is transmitted to another adjacent port.

For circulator (Circulator), usually there are three ports for tool, and the letter inputted from each port It number is typically set to be transmitted to another adjacent port in a manner of carry-over factor having the same and reflection coefficient.Therefore, respectively It can also be that there is directionality for input port while a port can be used as input port (Input Port) (Directivity) output port (Output Port).

On the other hand, it for isolator (Isolator), is set as in three ports connecting eventually in a port It holds resistance (Termination), and each port can only execute an effect.More specifically, by input port into The signal entered is transmitted by output port, and unlike this, it is sent to and is connected with by the signal that output port enters The terminal prot (Termination Port) of terminal resistance (Termination) simultaneously disappears.Therefore, in ideal isolator In the case of, the signal inputted from output port can be blocked, without being sent to input port.

This existing isolator with flowering structure by being constituted: center conductor (center conductor), is conductor material The wave transmissions medium of matter；First and second resonator (resonator) is wrapped up center conductor in the form of interlayer and makes to flow Resonance occurs for the electric wave for crossing center conductor；Permanent magnet provides magnetic force to first and second resonator；The pole piece of magnetic substance material (pole piece) is magnetized by permanent magnet and provides uniform magnetic force to first and second resonator；Nonmagnetic material material The isolator shell of matter, it is interior to be equipped with above structure component；The lid of magnetic substance material, set on isolator shell in sealing Structure member, and keep the certain magnetic field (magnetic field) being formed in around center conductor；And resistor (resistor), the echo (Return wave) from center conductor is converted into thermal energy and to external heat release.

More specifically, the magnetic force from permanent magnet is transferred uniformly into first and second resonator by pole piece, therefore First and second resonator forms certain magnetic field, and there are three the center conductors of terminal by the angle tool with 120 ° for electric wave It is rotated to a direction.In this state, when electric wave is applied to a terminal of center conductor, electric wave according to by first and The effect at Faraday rotation angle caused by second resonator, only flowing to the output terminal of center conductor, (it is relative to input terminal Son, in the angle for rotating 120 ° in one direction).On the other hand, from the subreflexive reflection electricity of the output end of center conductor Wave be induced to resistor terminal (its relative to output terminal, positioned in the angle that an identical direction rotates 120 °, and Relative to input terminal, positioned in the angle that an identical direction rotates 240 °), and be converted into after thermal energy into atmosphere Heat release and disappear, and be transferred to input terminal from the unnecessary electric wave that resistor terminal reflects (it be relative to resistor Terminal, in the angle for rotating 120 ° in same direction, and when relative to input terminal, in 360 ° of angle). Thus, it is suppressed that input terminal is transferred to from output end in the reflection wave of the energy of resistor terminal institute consumption degree, thus real The now isolation from output terminal to input terminal (Isolation).

Isolator is its characteristic to be determined according to the magnetic force of accompanying component, therefore be based on isolation according to prior art The design specification of device, can only restrictively alternative pack magnetic force range, and the position of the magnet for tuning be it is fixed, It makes it difficult to manufacture or tune the isolator with desired characteristic.Therefore, it is considered as that desired performance can be met easily The isolator that mode is tuned.
