The Basics of a Power Divider and the L-band Frequency: A Short Guide

Power dividers are passive RF components that divide a single input signal into two or more output signals holding only a minimal loss. Power dividers are commonly utilized in wireless systems to split up the power equally across the entire system. Out signals that are produced by the power divider are typically of the same amplitude and phase; however, based on fundamental requirements, dividers can change the amplitude and phase of the output signals.

Power dividers that work with a certain frequency band are also available to further better the wireless systems signal split up function of the RF components. One example of such is the L-band power divider; the L-band is a frequency range in the electromagnetic spectrum that has a frequency range that ranges from 1 to 2 GHz. The said frequency band can be usually seen in GPS carriers due to it receiving signal transmissions despite the heavy weather conditions.

To further understand both of these components, below are some of the basics of the two:

The Specifications of Power Dividers

Listed below are just some of the major specifications of a single power divider:

• The Power: This refers to the average input power that the power divider can hold.
• The Impedance Factor: Generally, power dividers are available in 50 ohm and 75 ohm configurations.
• The Configuration: This refers to the numerous ways of how the input signals are being divided by the power divider.
• The Insertion Loss: This refers to the lost signal when a single signal is being transformed into multiple signals commonly referred to as insertion loss, and this is measured in dB.
• The Package Type: Power dividers are available in a lot of packages. There are some that will usually include a Module with Connectors, Surface Mount, Plug-in, Flat Pack and Drop In.

The Applications of the L-band frequency

The quickly you understand the functions of the L-band frequency the better so here are some of the applications it’s being used on:

• In Mobile Services: In the European continent, the Electronic Communications Committee (ECC) of the European Conference of Postal and Telecommunications Administrations (CEPT) has corresponded a portion of the L-band (from 1452 to 1492 MH), allowing the individual cities to ratify this spectrum for fixed communications networks. The use of this spectrum can also offer an extra amount of bandwidth for communications from the base station to the mobile device.
• In Aircraft Surveillance: Every form of air transportation can use an automatic dependent surveillance-broadcast (ADS-B) tool at 1090 MHz to communicate positioning data to the ground as well as between them for traffic data and avoidance.
• In Amateur Radio: The Radio Regulations set by the International Telecommunication Union will permit amateur radio operations in the frequency range from 1240 to 1300 MHz. In addition, amateur satellite up-links are permitted in the range of 1260 to 1270 MHz. This is more commonly referred to as the 23-centimeter band by amateur radios and as the L-band by the amateur satellite.

These are just some of the fundamentals that govern an L-band power divider. It’s imperative that one has basic knowledge on the separate components of this RF device to fully comprehend its functionality.
