CPL-5214-20-SMA-79

RF Directional Coupler

The CPL-5214-20-SMA-79 is an RF directional coupler, which is widely used in circuit designs of satellite communication, ship-borne navigation equipment, military antennas, and other high-frequency communication facilities. It is an essential component in the RF signal path; it can offer a variety of features such as selective directivity, directional capability, power monitoring, impedance matching, and so forth.

The CPL-5214-20-SMA-79 is a two-port device, consisting of a primary main line and a secondary auxiliary line. The primary main line is connected to the transmit and receive antenna, while the secondary auxiliary line is connected to port A and B, where the RF signal is monitored.

The working principle of this device is based on the power divider and combiner. The power divider is used to divide the input signal into two parts and the combiner is used to combine two separate signals. The CPL-5214-20-SMA-79 works as a power divider in receive mode and as a power combiner in transmit mode.

The CPL-5214-20-SMA-79 can also serve as a directional coupler when two or more antennas are employed. In this case, the device works as a radio frequency (RF) controller to control and monitor the output power of the antenna. It can be used to adjust the transmission power of the antenna to ensure that the desired power output is achieved, while also providing a high degree of accuracy.

In addition to its use as a directional coupler, the CPL-5214-20-SMA-79 can also be used as a power monitor. The device is equipped with both a directivity indicator and a power meter, which can be used to measure and adjust the signal level. This feature is especially useful when the signal has to be distributed over a wide area.

The CPL-5214-20-SMA-79 is a reliable and efficient RF directional coupler. It is designed to provide a high degree of accuracy and stability, as well as a wide range of features and capabilities. It is an ideal choice for RF signal monitoring, power monitoring, and antenna control applications.
