What does coupling mean in electricity? What is a coupler?

A logic integrated circuit that operates in the unsaturated region when the transistor is turned on. There are two outputs, "or" and "or". It can form various logical relationships. It is characterized by fast switching speed, even up to sub-nanoseconds, but high power consumption and poor anti-interference power.

Charge-coupled devices:

A device made by using a small number of carriers to store and transfer in a surface barrier. It is composed of an array of metal oxide semiconductor capacitors. There are two types: line array and area array.

It can be used as a delay line and shift register, and can also be used for analog signal processing and storage. Charge-coupled devices are almost exclusively used in current cameras.

A coupler is a passive device that distributes power (the power divider is a special case of the coupler), and the 60dB coupler means that the output power of the branch channel is the input power minus 60dB, and the output power of the main channel is the residual power. If the input power of the coupling is 60dBm, the output power of the branch channel is 0dBm, that is, 1MW, and the output power of the main channel is 1000000-1=999999MW of power, but the general main channel has insertion loss (the branch channel also has insertion loss, but generally a little more power will be allocated to offset the insertion loss), and the output power is smaller. The 3db bridge is a kind of combiner, two in and two out, the bridge and coupler are not a type of passive device.

Analysis: Coupling refers to a metric in which two entities depend on each other. It is divided into the following types:

Non-direct coupling: There is no direct relationship between the two modules, and the connection between them is entirely achieved through the control and invocation of the main module.

Data coupling: When one module accesses another, the input and output information is exchanged through simple data parameters (not control parameters, common data structures, or external variables).

Tag coupling: A set of modules pass record information through a parameter table, which is marker coupling. This record is a substructure of a data structure, not a simple variable.

Control coupling: If a module clearly controls the function of selecting another module by transmitting control information such as switches, logos, names, etc., it is control coupling.

External coupling: A set of modules that all access the same global simple variable instead of the same global data structure, and do not pass the information of that global variable through a parameter table, is called external coupling.

Common coupling: If a set of modules all access the same common data environment, the coupling between them is called public coupling. A common data environment can be a global data structure, a shared communication area, a common footprint for memory, and so on.

Content coupling: Content coupling occurs between two modules if:

1) One module directly accesses the internal data of another module;

2) One module does not go inside another module through the normal entrance of the collapse brigade;

3) Some of the two modules overlap (only in the assembly language);

4) One module has multiple entrances.

Coupling strength. The strength of the coupling depends on the following factors: (1) the invocation of one module to another; (2) the amount of data transmitted from one module to another; (3) the amount of control exerted by one module to another; (4) The complexity of the interface between the modules.

Couplings can be divided into the following types in order from strongest to weakest:

1) Content coupling. Content coupling occurs when one module directly modifies or manipulates the data of another module, or directly transfers it to another module. At this point, the module being modified is completely dependent on the module that modified it.

2) Common coupling. When two or more modules collectively reference a global data item, it is called a common coupling.

3) Control coupling. A module transmits a signal (such as a switch value, flag amount, etc.) on the interface to control another module, and the action of the module receiving the signal is adjusted according to the signal value, which is called control coupling.

4) Marker coupling. Complex internal data structures are passed between modules through parameters, which is called tag coupling. Changes to this data structure will cause the related modules to change.

5) Data coupling. Elementary types of data are passed between modules through parameters, which is called data coupling.

6) Non-direct coupling. When there is no information transfer between modules, it is a non-direct coupling.

If there must be coupling between modules, try to use data coupling, use less control coupling, limit the scope of common coupling, and resolutely avoid using content coupling.

A coupler is a component that realizes the need to divide the power of one microwave into several channels in a microwave system. The main friendliness function of the coupler is to divide the microwave power into several channels proportionally in the microwave system, mainly to achieve power distribution.

The main applications of the coupler are: the application of the logic circuit, the application of the solid switch, the application of the trigger circuit, the application of the pulse amplification circuit, the application of the best circuit, and the application of the vertical application in special occasions.

Direct Coupling Circuits:

A circuit that connects the output of the previous stage directly to the input of the next stage.

Disadvantages of the direct coupling method:

The direct coupling mode is used to connect the direct flow paths between the stages, so the static working points affect each other, and there is a zero drift phenomenon.

Advantages of the direct coupling method:

With good low-frequency characteristics, the key balance can amplify the signal that changes slowly; Since there are no large-capacitance capacitors in the circuit, it is easy to integrate all the circuits on a single silicon wafer to form an integrated circuit.

The term coupling is explained as follows: in physics, it refers to the phenomenon that two or more systems or two forms of motion interact with each other and even unite with each other. For example, the step-by-step amplification of signals between amplifier stages is through resistor-capacitance coupling or transformer coupling; The mutual inductance between the two coils is through the coupling of the magnetic field.

2. Network Explanation.

CouplingIn the field of electronics and telecommunications, coupling refers to the process of energy propagating from one medium (e.g., a metal wire, optical fiber) to another. In electronics, coupling refers to the transfer of energy from one part of an electrical circuit to another.

For example, with conductivecoupling, energy is propagated from a voltage source to a load. Capacitors allow the AC and DC parts of a circuit to be coupled by allowing the AC component to pass through and block the DC component. The transformer can also act as a coupling medium, and the appropriate impedance matching can be achieved by configuring the appropriate impedance at both ends.
