What Are Power Dividers and Directional Couplers?

Directional couplers and power dividers are devices that are prevalent in radio technology. They combine electromagnetic power in transmission lines so signals can be used in different circuits. They only combine power that flows in one direction. Any power that enters an output port is put into an isolated port but will not enter the main signal port. Furthermore, special couplers are available that can equally split power between two output ports, known as hybrid combiners. Read on to learn more about the different types of couplers and dividers.

Directional Couplers

The most popular combiner is responsible for pairing transmission lines. They are found in a variety of technologies. You may have heard of them as coupled transmission lines or backward couplers.

Similarly, branch-line couplers have multiple parallel transmission lines combined by branch lines between them. The more sections in this type of coupler, the higher the ratio of impedances is. To reduce this, many manufacturers limit these couplers, so they only hold three lines. However, they generally do not have a wide bandwidth. Instead, they are popular because they can handle high amounts of power.

Power Dividers

The earliest power dividers were known as T-junctions. These suffer from poor isolation. These three port systems are not very efficient and lead to higher losses as well. However, four-port power dividers have become popular and are much more efficient. You will likely hear these called  90-degree or hybrid couplers and hybrid ring or 180-degree couplers. Additionally, there are other types of dividers which have more than four ports. However, these tend to be inefficient, as well.

Power dividers and directional couplers are common devices in radio technology. Directional couplers are designed to combine electromagnetic power in transmission lines. Meanwhile, power dividers are designed for splitting electromagnetic power. Knowing which types are available can help you figure out what you need.…

3 Ways Satellites Improve People’s Lives

Many people go through their everyday lives without stopping to think about all the things that make what they do possible. Satellites are not seen or thought about by most people, but they play an important role in many people’s daily routines. The aid in communication around the globe, collect data that is used in weather prediction and help people navigate unfamiliar areas.

1. Communication

While the use of cellphones continues to rise in popularity around the world, satellite phones are still valuable. Remote areas without cellphone towers depend on satellites for their communication needs. The incredible technology in satellites, like microwave resonators, uses the transmission of radio waves and microwaves to facilitate communication.

2. Weather Prediction

Some satellites collect data about weather patterns observed from space. This information includes wind speed and direction, temperature and cloud movements. Once the data has been collected and analyzed by professionals, weather predictions can be made. While the accuracy of the predictions is not 100% at all times, thanks to the use of satellites and advanced computer programs, it has been drastically improved in the modern period.

3. Guidance

The use of the Global Positioning System by the public has increased rapidly over the past couple of decades. As the technology has improved, it has gone from devices that were specifically designed to only handle GPS signals to being integrated directly into new vehicles and smartphones. Satellites can pinpoint the location of the device to assist in the mapping of the area and allow the program to devise a route to another place. This can allow people to travel to new places more freely, as they do not have to struggle with reading a map or atlas on the way to their destination.

As more people around the world grow to depend on the use of technology in their daily lives, satellites will likely become even more important. Think about satellites and all the other things that make modern life convenient next time a phone call comes in or a storm is predicted.…

In an age of advanced technology like today, buying a laptop must be with full consideration. If in the past we might only buy by considering the capacity of the battery, screen and storage space. But now you also have to consider processors that are tailored to the needs of users.

Because times have evolved, laptops of various types and types and specifications are sold freely. Ranging from cheap to expensive, everything is on the market. But you must pay close attention to whether the laptop is quality or not. The right way is to bring a friend who knows the technology when buying it. here are some tips that you should consider before buying a laptop

Pay attention to the brand

The Top 3 Things To Know About Silicon Wafers

Most people don’t think about the complexity of the technology that they hold in their hand when using their smartphone. We all know that mobile phones can load apps, show our GPS location, and send text messages, but do you know what components go into making this miracle device?

What Are Silicon Wafers?

Silicon wafers were created by Mohamed Atalla in the 1950s. He created a silicon wafer with a layer of si02 which allows electricity to flow on a conductive silicon layer. In 1954, Atalla officially announced the first silicon transistor that became available commercially.

Since then, these silicon wafers have been used by every major electronic company to create microchips in electronic devices. This includes every day household items such as ovens, microwaves, cell phones, and computers just to name a few. If your device uses electricity, it most likely uses silicon wafers to divert and conduct electricity to make it function.

The Size Doesn’t Matter

Many people think that silicon wafers have to be small in order to function properly. In fact, silicon wafers can be any thickness and will still function properly. Thickness of silicon wafers differs based on the application they will be used for. For example, a large appliance may use a thicker silicon wafer than that of a small device such as a cell phone or laptop.

Wafers Can Be Cleaned

Overtime, silicon wafers can collect dust particles, or even be damaged when other components are maintained or swapped out. When this happens, these wafers can be repaired through thin film deposition services to make them look and function like new.

Having silicon wafers repaired, instead of thrown away, can save large electronic manufacturers time and money as they can reuse silicon wafers that may be damaged.

As you can see, silicon wafers play a major part in our everyday lives. Understanding the components that exist in our electronics can help us to appreciate and take better care of them.…

Tips on Choosing a Laptop As Needed

LaptopNot infrequently we are confused when wanting to replace a laptop or buy a new laptop for the appropriate needs. Because there are many brands with different specifications.
