RF directional couplers are electronic devices that couple part of the power travelling along a transmission line to another line which is terminated in a suitable impedance. The commonly used model, CPL-5213-06-TNC-79, is a miniature, high isolation, wet-tested RF directional coupler suitable for UHF applications. This coupler offers excellent performance in a compact package.

The CPL-5213-06-TNC-79 is a four-port device designed to measure the isolated signals in UHF frequency range with higher accuracy. The coupler measures the isolated signal with the help of four branches connected in series, out of which one being the main line, the other three being the isolated arms. It is also used to balance unequal coaxial lines as well as for equalizing long single coaxial lines.

The CPL-5213-06-TNC-79 features a low insertion loss, wide dynamic range, high isolation, and high return loss. The insertion loss is below 0.5dB in the frequency range 790-805MHz, and the maximum return loss of the coupler is 30dB. The isolation of the RF directional coupler is greater than 35dB in the operating frequency range and up to 60dB in the lower frequency range. The coupler offers excellent performance and is ideal for applications such as medical equipment, industrial equipment, military and aerospace, communications, and distributed antenna systems.

The CPL-5213-06-TNC-79 is designed to withstand harsh environmental conditions and temperature extremes, and is suitable for use in both indoor and outdoor applications. The coupler is moisture and corrosion proof and is designed to minimize the risks of electromagnetic interference. The coupler is also resistant to shock and vibration, making it suitable for use in heavy-duty applications.

The working principle of the CPL-5213-06-TNC-79 is based on the idea of Direction Coupling. It works on the principal of allowing a fraction of the transmitted RF power to be diverted to a separate line. The RF directional coupler works to provide the signal measurement, while the four ports are connected in a specific manner to provide the power-splitting functionality.

The CPL-5213-06-TNC-79 is a high-performance RF directional coupler, ideal for use in various applications, from medical to aerospace. It offers excellent performance in a compact package, with low insertion loss, wide dynamic frequency range, high-isolation, and high return loss. With its robust design, it is suitable for both indoor and outdoor applications, and withstands harsh environmental conditions and vibration.
