RF directional couplers are passive RF devices used to sample the power of a signal on one transmission line over the entire set of frequencies in the chosen frequency band. In this way, they are essential components for the accurate testing and measurement of electrical signals and components. The CPL-5213-30-TNC-79 is an RF directional coupler designed for use in frequencies up to 10 GHz and manufactured by Kaelus. This unit is composed of an electromagnetic TNC connector and a dielectric protected enclosed housing. In addition, the unit is fitted with one female TNC connector for the Input port and one female TNC connector for the Through port. The unit has a coupled output port with a female TNC connector.

The CPL-5213-30-TNC-79 RF directional coupler is typically used as a signal sampling tool to allow continuous monitoring of an RF system. Its main characteristic is the ability to measure the amplitude of the signal over a wide frequency range while isolating noise from the overall signal. It is also used to monitor signals for RF downlink performance measurements, power test measurements, and spectral parameters. Additionally, it is designed to perform better when used for directional measurements in the X-band.

The working principle of the CPL-5213-30-TNC-79 RF directional coupler is based on the physics of resonance and transmission line theory. This type of coupler has an input transmission line that is shorted at the midpoint while the transmission line is terminated to match the system impedance at the end. This results in a half-wavelength dipole structure in which the two halves are connected in series with the source. The source power is detected on either side of the dipole and is connected to a balanced detector unit that makes use of a diode bridge or a transformer to measure its amplitude.

The input signal is then divided into two equal-amplitude portions and reconstructed to form a single output signal. The output signal can be used for various purposes, such as power measurements, network monitoring or signal analysis. In addition, the CPL-5213-30-TNC-79 RF directional coupler allows for the use of different types of transmission line impedances, which makes it suitable for use in a wide variety of applications. Furthermore, the unit has a broad frequency response, with a wide dynamic range for more precise measurements.

In summary, the CPL-5213-30-TNC-79 RF directional coupler is an ideal choice for all high-frequency applications, such as radio frequency downlink performance measurements, power test measurements, and spectral parameters. The unit is designed to operate up to 10 GHz and has a wide dynamic range for more precise measurements. It works on the principle of resonance and transmission line theory and is suitable for a wide variety of different transmission line impedances. This ensures that the unit can be used in a variety of applications and provides more accurate results compared to other directional couplers on the market.
