C-Band Power Divider – The Basics of the C-band Frequency and Key Specifications for Power Dividers

Among the entire frequency band, the C-band was the first one to be used for every satellite communication systems. However, when the C-band became overloaded (because the same frequency band was being utilized by terrestrial microwave links) other satellites that were compatible with the other frequency bands were then manufactured, namely the Ku-band frequency. First and foremost, a C-band frequency is the termed referred to the portion in the electromagnetic spectrum that has a frequency range that ranges from 4 to 8 GHz.

Besides from satellite communication systems, the C-band frequency also has uses in RF and microwave components; one example of such is the C-band power divider. Power dividers main function is to take an input signal and then divides it into two or more output signals with a small amount of losses. They’re commonly utilized in every wireless system to divide the power across the system.

The Key Specifications of a Power Divider

Below are some of the key specifications that every power divider has. It’s imperative that one should be completely aware of what they are before buying or using one:

• Configuration: The different methods the input signal is being divided
• Power: The average input power the divider can manage
• Insertion Loss: The signal lost when a single signal is being transformed into multiple frequencies is referred to as insertion loss, and it’s measured in decibels (dB)
• Impedance: A single power divider is typically available in both 50 and 75 ohms configurations.

The C-band and the Ku-Band: Which is better?

As mentioned above, the C-band frequency is the most used frequency band for satellite communications. However, due to the fact that the said frequency is used in terrestrial microwave links, another frequency band is now being used as an alternative for the C-band satellite system; namely the Ku-band frequency.

The question now here is, “Which of the two frequency bands is better?” The answer would be none because both of these frequency bands provide high quality satellite transmissions. However, if choosing the best one is still a problem, one way to pinpoint the best frequency signal is by the external factors that are present. The choice of which frequency band would be better for any system is determined by the external factors.

One of these factors is the location. For example, if one is planning to set up a satellite system and is situated in the Middle East, the Ku-band frequency is highly efficient for that area rather than the C-band. This is due to the fact that the Ku-band satellites are not that expensive and the smaller dish size it has makes it less suspicious and easier to move when changing location is necessary. On the other hand, if the subscriber is in need of a higher bandwidth, the C-band frequency is more suited to provide the required bandwidth.

In RF components, the C-band frequency working in the C-band power divider help better transmit the input signal to the dividers for output signals to be produced due to it being the very first frequency band to be used in satellite communications, and by it having higher amounts of bandwidth.
