​Railtex is the UK’s premier exhibition of railway equipment, systems and services. Taking place from 14th – 16th May at NEC Birmingham, Aspen Electronics will be attending the event to showcase our range of compliance, safety and test equipment for applications including: EMC compliance, EMF monitoring and power measurement.

Each year Railtex attracts over 10,000 industry specialists including rail industry managers, buyers and engineers, along with more than 100 exhibiting companies.

Aspen Electronics will be on stand F93 and will be joined by our technology partners Bird and Wavecontrol. Throughout the three-day event our test, measurement and compliance experts will be available to discuss how Aspen Electronics can provide solutions for your exact test requirements.

SAF Tehnika's e-band spectrum analyser has won a Product Innovation Award at EDI CON China 2019  in the Test & Measurement Category.

​EDI CON China 2019 has announced the winners and presented the trophies to company representatives in its second annual EDI CON CHINA Product Innovation Awards. SAF Tehnika's E-band Spectrum Compact has won the Innovation award in the Test & Measurement category.

The EDI CON Product Innovation Awards honor products introduced in the last year that have had the greatest impact on the industry, providing the tools necessary to bring on the next generation of electronic design innovations.

E-band Spectrum Compact is the world's first battery-operated handheld spectrum analyzer for the 70 - 87 GHz range. It is a ready-to-go solution for E-band link troubleshooting, maintenance and installation. Device has a -90 dBm leading displayed average noise level (DANL) at 10MHz RBW, which makes it a perfect tool for interference detection on installed paths.

Couplers and power dividers are two of the most fundamental components of electronic devices used for the transmission and reception of radio waves. They both are classified as passive Radio Frequency (RF) components and can be found in almost every electronic device that is used for telecommunication purposes. 

Many people think that couplers and power dividers are the same thing. On the contrary, several prominent differences separate the two RF components. Not only do they differ in the functions they perform, they also have different mechanisms for dividing radio signals. 

The Working Of Power Dividers And Couplers 

Couplers and power dividers are termed as passive devices because they don’t contain an energy source that can be used to modify the radio signals that they deal with. However, the basic function of power dividers and couplers is the same: they split incoming signals. Since the input port of a unidirectional power splitter has a greater resistance than the output ports, it is an ideal choice for applications requiring a calibrating device. 

What Are The Differences Between Power Dividers And Couplers?

Here are some of the major differences between coupler and power dividers:

The Number Of Ports

A directional coupler contains 4 ports that allow radio signals to be split unequally. The power of the incoming signal is split at each port with a portion of it going to the next one. In ideal circumstances, the fourth port is completely isolated and no power flows through it. 

On the other hand, power dividers contain 3 ports that split radio signals into two equal parts containing roughly the same amount of power. The two output ports produce signals of equal amplitude and are phase balanced. 

Isolated Port

Power dividers do not contain a single isolated port, whereas one of the output ports of a coupler is always isolated.

Heat Loss Property

An unidirectional or multidirectional coupler has zero power loss because none of the energy passing through the coupler system is transformed into useless heat energy. On the other hand, power dividers may experience a tiny amount of power loss when energy flows through it. 

Applications

The properties of a radio signal, such as its frequency and power, can be measured by using signal sampling techniques. Power dividers are ideal devices for this purpose as they can divert power to several radio antennae at the same time.

Couplers, however, capture a certain amount of energy from transmission lines and are commonly used to transfer a signal from one radio system to another.
