Couplers

Coupler

Couplers are of electronic device that joints two electronic circuits or sockets

In an electronic device there are many types of couplers which are known as acoustic couplers

 

In telecommunication device known as a directional coupler

 

A kind of laser mirror known as an output coupler.

 

A connector between two moving parts to relay the motion, such as a Universal joint or an Oldham coupler

 

Acoustic couplers: In these types of couplers transmission of digital data is permitted between modem of computer terminal and telephone line in either direction without making direct connections.

 

Directional coupler:- This types of couplers have four parts in which one is as input ,one is as 'through port where most of incoming signals exists ,one is considered as coupled port where a fixed fraction of input signals appears mostly in dBs and an isolated port which is usually terminated. If the signal is reversed so that it enters in “through port”, most of it exits the "input" port, but the coupled port is now the port that was previously regarded as the "isolated port". The coupled port is a function of which port is the incident port.

Output coupler: -An output coupler is a partially reflective mirror which is used in lasers to extract a portion of laser beam from the optical resonator

 

Oldham coupler:- Through this torque is transferred between two parallel,It has three discs , one coupled to input , one to the output and middle disc is joined to the first two by torque and groove .The Torque and groove on one side is perpendicular to the torque and groove on other .These types of coplers are most compact .

The coupler is named for John Oldham who invented in Ireland in 1820.

Features

 

1. High Performance

The high frequency characteristics of couplers feature extremely low loss, a high degree of matching, and high isolation.

 

2. Power Uniform Distribution and 90°Phase Difference Type

In this coupler has one input, two output (or two input, one output) power uniform distribution type having a 90°phase difference between the two outputs (or two inputs).

 

3. Miniature and Lightweight

Corrosion-resistant aluminum is used in the couplers for the case and some manufacturers has original pattern design of these type of couplers

Which uses a stripline triplate method enables the couplers to be miniature and lightweight?

 

4. Couplers with SMA Connectors

Use of SMA connectors which feature stainless steel for the exterior

Cladding makes these couplers durable.

 

5. Equipped with Tabs

Tabs permit direct mounting to surface circuits in the couplers

 

6. High Power Type

This type of coupler can be used with up to 100 W of power

.

Applications:-

Couplers can be used in mobile phones base stations

Measurement equipment

Radio communication equipment

Couplers as a communication tool can be vital for the public safety and security services in a critical mission".

Any untrained staff can use these types as these are so simple Antenna couplers
