A directional coupler, also known as an RF directional coupler, is a two-port network element, which is used to couple signals in RF (radio frequency) circuits. An RF directional coupler is a passive, non-reciprocal device, which allows the user to monitor and measure power levels of signals in an RF system. The directional coupler has the ability to couple or to decouple signals from a common transmission line.

The X3C35F1-05S directional coupler is a 100 to 1000 MHz frequency range waveguide directional coupler. It is a dual directional coupler which provides the user with the ability to measure forward and reverse power levels separately. The coupling factor is 10 dB and it has a designed VSWR of 1.15:1.

The X3C35F1-05S directional coupler is designed for insertion in waveguide systems to split signals into two separate parts. The one part is routed to the monitoring instrument while the other part is allowed to pass unhindered. The RF directional coupler is mainly used in radio communication systems, CATV systems, and broadcast radio and television systems.

The working principle behind a directional coupler is based on the principles of electromagnetic field theory. It is based on the fact that the electric fields of two parallel conductors vary in magnitude and phase with respect to each other depending on the distance between them. By placing two similarly arranged conductors at a certain distance from each other, it becomes possible to measure their voltage differences which indicates the power of the signals on these conductors.

The X3C35F1-05S directional coupler uses a hybrid design to make power measurement even more accurate. This particular design uses two 90° hybrids, one for each of the two ports, as well as a 180° hybrid. This ensures that all power coupled into the monitoring port is equal to the power coupled from the main port, and any power not coupled into the monitoring port can be accurately measured.

The X3C35F1-05S directional coupler is a very useful device in RF systems. It is useful for measuring the power level of signals in an RF system, as well as for monitoring and measuring power levels of multiple signals. It is also used in CATV systems for the purpose of impedance matching, as well as for measuring the power of signals in forward and reverse directions.
