As a wide-range and varied range of RF components, RF directional couplers are commonly used in radio systems. Among all kinds of RF directional couplers, 1K0265-3 stands out for its unique performance. In this article, we will look at the application field of 1K0265-3 and its working principle.

Generally speaking, 1K0265-3 RF directional coupler can apply to the measured performance of almost all wireless communication systems, including DAB (Digital Audio Broadcasting), TETRA (Terrestrial Trunked Radio) and Wi-Fi. It is specifically designed for large signal impedance matching, thus creating optimal performance for the given application. In addition, its low loss characteristics make it an ideal option for testing and design in the areas of high frequency shielding design and RFIC (Radio Frequency Integrated Circuit).

In terms of the working principle of 1K0265-3 RF directional coupler, it is basically based on the transmission line theory. The basic operation principle is ,when the parameter of the transmission line is fixed, the output voltage will be proportional to the input power, and the output will be 180 degree out of phase with the input power. Therefore, the 1K0265-3 RF directional coupler is designed to accurately measure forward and reverse power through two resistors connected in anti-phase, and the signal output is represented by a 180 degree out of phase resistance.

To sum up, 1K0265-3 RF directional coupler can be used in most of the wireless communication systems, especially for signal impedance matching, shielding design and RFIC. Its working principle is based on the transmission line theory with the output signal generated in 180 degree out of phase with the input power.
