Working principle

The RF directional couplers are components that measure the power transmitted from one port to another. They typically comprise a set of two or more coupled transmission lines, which are physically arranged such as in a pigtail. The coupled lines are then connected to port connectors. The power coupled from one port to another is a function of the internal line length, the line quality, and the coupling factor. The design of the CPL-5217-20-TNC-79 provides a fixed line length, superior line quality, and a high coupling factor, which allows for accurate and repeatable power measurements.

The forward coupling of the coupler is the magnitude of the power coupled from the input port to the output port while the reverse coupling is the magnitude of the power coupled from the output port to the input port. The wide-angle design of the CPL-5217-20-TNC-79 features low insertion loss, excellent return loss, and wide dynamic range. The wide-angle design makes it suitable for use in various applications.

Another feature of the CPL-5217-20-TNC-79 is its wide bandwidth. This ensures that it has the ability to measure power over a wide frequency range accurately. The wide frequency range increases the accuracy and versatility of the device.

The CPL-5217-20-TNC-79 also features a VSWR monitor port. This port allows users to check for degrees of mismatch relative to the system impedance. This is valuable in obtaining precise power measurements. The monitor port is also useful for identifying the causes for any power loss that may have occurred during the transmission and reception.

In conclusion, the CPL-5217-20-TNC-79 is a high-performance, high-dynamic range, wide-band, wide-angle, RF directional coupler designed for use with UHF/VHF frequencies, specifically designed for wireless local loop systems, base station RF systems, broadcast and satellite communication systems, and electromagnetic field measurement systems. Its wide-angle design, wide frequency range, low insertion loss and excellent return loss ensure accurate power measurements. Its integrated monitor port is useful in identifying power losses along the transmission or reception paths.
