PWD-5520-12-NNN-79

Introduction

RF Power Dividers/Splitters are devices that are used to divide an RF signal into multiple copies with the same amplitude and phase. The PWD-5520-12-NNN-79 is a type of power divider that has various applications and a specific working principle.

Applications

The PWD-5520-12-NNN-79 power divider is used in two main applications. The first application is for signal distribution. The divider can be used to distribute an RF signal into several outputs, group them into different segments and amplify them if necessary. It is suitable for commercial broadcast transmission, power line communication and direct broadcasting systems.

The second application is signal combining. The divider can be used to combine multiple input signals into one output. This is useful in applications such as antenna remoting and base station antenna combining. This enables the user to output a single signal with multiple inputs while avoiding interference and improving signal strength.

The PWD-5520-12-NNN-79 power divider also has a wide range of other applications, including: communications amplifiers, telemetry systems, GPS signal processing, frequency hopping, multi-band antennas and antenna arrays.

Working Principle

The PWD-5520-12-NNN-79 power divider is a three-way, Wilkinson type power divider. It consists of three outputs, two main branches and one tap section. The two main branches are resistively coupled and resistively terminated, while the tap section is isolated from them both by a combination of resistive and capacitive coupling devices. The power divider operates by splitting the input signal into two main branches which are in turn combined and recombined in the tap section. This process creates multiple copies of the original signal with a 50/50 power split between the two main branches.

The PWD-5520-12-NNN-79 power divider is designed such that the outputs are precisely matched. This is achieved by controlling the resistive coupling and termination of the main branches and the capacitive coupling in the tap section. This ensures that the signal is carefully divided into the correct amount of copies, with the correct amplitude and phase.

Conclusion

The PWD-5520-12-NNN-79 power divider is a three-way Wilkinson type power divider. It has two applications, signal distribution and signal combining, and is suitable for a wide range of applications. The power divider works by splitting the input signal into two main branches and combining them in the tap section, creating multiple copies of the original signal with a 50/50 power split. The outputs are precisely matched through a combination of resistive and capacitive coupling devices.
