A maximum of 10 watt average and two watt peak power ratings are available for CPL-5214-10-NNN-79 Directional Couplers.

Application Field

The CPL-5214-10-NNN-79 series Directional Couplers are designed for the applications in various wireless and communication systems. The CPL-5214-10-NNN-79 series Directional Couplers can be used in the field of microwave amplify, radar and navigation systems. It can also be used as monitoring tool in antenna development or distortion analysis.

In addition, the CPL-5214-10-NNN-79 can be used in various wireless communications, such as radio broadcast and radio LAN, where signal power measurements are needed.

Working Principle

The CPL-5214-10-NNN-79 Directional Coupler utilizes a dual dielectric waveguide technology which combines the two main waveguide principles-magnetism and directivity. It provides a highest directivity available and the utmost accuracy when it comes to power measurement.

The CPL-5214-10-NNN-79 series are constructed from two waveguides arranged in parallel with an outer cover to provide the necessary mechanical protection. The inner waveguide is referred to as the line waveguide and it is connected to the port or receptacle where the signal propagates. The outer waveguide is known as the loop waveguide and it carries the signal from the main waveguide and couples it to the sense waveguide that leads to the power meter.

The Directional Coupler directs a certain amount of signal power to the sense waveguide while allowing the remaining signal power to continue to the main waveguide. The power level at the sense waveguide is analyzed and measured by the power meter and displayed as a value on the LCD screen.

Conclusion

The CPL-5214-10-NNN-79 series is a type of RF Directional Coupler that offers excellent power measurement accuracy for various applications in wireless and communications systems. It utilizes a dual dielectric waveguide technology to provide the necessary directivity and accuracy when it comes to power measurement.
