CPL-5048-10-NNN-79 Application Field and Working Principle

The CPL-5048-10-NNN-79 is a type of RF directional coupler which is used to measure the amount of power that is flowing in a transmission line. This device is a passive component, which means that it does not require power from an external source to function. It can also be used to tap off a portion of the line for measurement, or to sample the signal to other parts of the system. This type of coupler is often found in telecommunications systems, test equipment, and radar systems.

Description

The CPL-5048-10-NNN-79 is a directional coupler which works in the frequency range of 50 MHz to 8 GHz. It is a single port device, meaning that there is only one input and one output port. The device features a directivity of 30 dB and a coupling factor of 10 dB. It is a 75 ohm device, and the ports are terminated with SMA connectors. The device housing is made from aluminum and includes a mounting bracket.

Working Principle

The CPL-5048-10-NNN-79 works by passing the incoming RF signal to a pair of two-conductor transmission lines (called “pairs”) which are located inside the device. These pairs are set at 90 degrees from one another, so that when one pair is receiving a signal, the other pair is not. The RF signal is then split into two components – one component is sent to the output port, while the other component is routed to a restraining resistor. This resistor is set to a specific value, which determines the amount of signal that is sent to the output port. The amount of signal sent to the output port is referred to as the coupling factor, which is indicated by the 10 dB marking on the device.

Applications

The CPL-5048-10-NNN-79 is commonly used in a wide variety of applications, including:

• Telecommunications systems
• Test equipment
• Radar systems
• Broadcast systems
• Satellite systems
• Military communications
• Aircraft communications
• Navigational systems

RF directional couplers, such as the CPL-5048-10-NNN-79, are a critical and essential component of any RF system, and are essential for providing accurate measurements of the RF power flow and for routing a portion of the signal to other parts of the system. They can also be used for signal sampling, making them a versatile and essential component for any RF system.
