The CPL-5216-20-SMA-79 RF Directional Coupler is a two-port coupled device with an arrangement of two ports in a cascade configuration. The coupler is designed and manufactured with very high precision to provide accurate readings from both output ports. This coupled system uses a combination of inductors and capacitors to transfer the signal from one port to the other in a balanced manner. The two ports are typically referred to as the input port and the output port.

Application Field

The CPL-5216-20-SMA-79 RF Directional Coupler is mainly used to measure the signal coming in from one port and the amount of signal going out from the other port. It is most commonly used in instrumentation and communications systems. It is widely used in the broadcast and wireless industries, as well as in medical and military applications. The device allows engineers to unit test the components of a wireless system to make sure that they are functioning as expected.

For example, it can be used in wireless communication systems to check the signal’s strength or the impedance balance, or to measure the sensitivity and frequency of the system. It can also be used in radio direction finding systems to identify a transmitter’s location or to determine the angle of arrival of a signal.

Working Principle

The CPL-5216-20-SMA-79 RF Directional Coupler works on the principle of mutual inductance. This means that the coupled connection between the two ports has an electromechanical connection with no electrical connection. The electromechanical connection is created by a pair of electromagnetic coils that are placed on either side of the coupled device. These coils form a closed loop of magnetic field that allows the input signal to be transferred with minimal power loss.

When a signal is sent in from the input port, it will travel through the inductors and capacitors of the device and will be coupled between the two ports with minimal power consumption. The coupled signal will travel to the output port in a balanced manner and will contain the frequency, amplitude, and power of the original signal. This allows the device to measure the signal’s power, frequency, and impedance balance.

The CPL-5216-20-SMA-79 RF Directional Coupler is a highly precise device that can be used in a variety of applications. It can be used to measure the signal’s strength or impedance balance, to measure the sensitivity and frequency of a wireless system, or to identify a transmitter’s location. Thanks to its small size and high precision, it is highly versatile and can be used in a variety of applications.
