CPL-5232-10-NNN-79

RF Directional Couplers are one of the most commonly used devices in microwave electronics and communication systems. This article will discuss the CPL-5232-10-NNN-79 RF Directional Coupler and its application field and working principle.

Introduction to RF Directional Couplers

RF Directional Couplers are devices used to couple signals together and allow for the accurate transfer of signals from one port to another. This coupling process is known as “directional” coupling because the signal is usually only transferred in a single direction. Directional couplers are used in radio frequency (RF) applications where signals need to be averaged or measured. The couplers also enable the device to monitor signal amplitude without its own interference.

CPL-5232-10-NNN-79 RF Directional Coupler

The CPL-5232-10-NNN-79 RF directional coupler is a highly reliable four-port device that is designed for use in stringent military and aerospace applications. The coupler comprises four ports, two of which allow for the coupling of signals. The directional coupler is designed to be highly directional, allowing signals from one port to be transferred simultaneously to another port and then out of the device.

The CPL-5232-10-NNN-79 has a frequency range of DC-18G Hz and is capable of handling power up to 1.3kW. It has a directivity of 20dB and an isolation of 60 dB. The coupler is extremely compact, with an overall size of just 7.00”x 2.38”x 1.50”. Additionally, it is designed to withstand environmental conditions such as shock, vibration and temperature.

Application Field

The CPL-5232-10-NNN-79 is designed for use in a variety of RF applications, including military communications, radar systems, test and measurement, and satellite communications. The coupler can be used in devices ranging from aircraft to ground control stations. Additionally, the coupler is suitable for use in high-interference environments such as those encountered in electromagnetic compatibility (EMC) testing and communication jamming.

Working Principle

The CPL-5232-10-NNN-79 directional coupler works on the principle of balanced transmission lines. In this type of transmission line, the signal is directed from port 1 to port 2. Port 3 of the coupler is connected to ground. This detuning connection reduces the interaction between the two ports. Additionally, port 4 of the coupler is connected to the input port of the device. As a result, the signal fed to port 4 will be coupled to port 2, while port 1 acts as an output port. The directivity of the device allows the signal to travel in a single direction only.

Conclusion

The CPL-5232-10-NNN-79 RF directional coupler provides an efficient and reliable signal transfer from one port to another. The device is designed to withstand harsh environmental conditions and provide accurate and consistent signal transfer between ports. This makes it suited for a wide variety of military and aerospace applications.
