A RF Directional Coupler, such as the 1Z0280-3, is an instrument used for measuring power or insertion loss in a given RF transmission line. Typically mounted on the end of a coaxial cable or antenna, they are designed to sample a portion of the current passing through the coaxial cable and then split it into two separate lines. This allows the current to be monitored at two independent outputs at the other end of the device.The 1Z0280-3 is designed to provide highly accurate insertion loss measurements with minimal insertion loss. It features a frequency range of 50MHz to 6GHz, insertion losses of less than 1.5dB, accuracy of ±1.5dB and isolation of more than 15dB. It is also designed for use in RF applications such as microwave transmission systems, cellular base station systems, avionics systems, military communication systems and GPS systems.As with all RF directional couplers, the 1Z0280-3 works by splitting the base signal into two separate paths and then combining them again at the other end. This allows a portion of the signal to be sent to a secondary path, while the remainder is sent to the main communications line. By measuring the differences between the input and output signals, the directional coupler can accurately measure the insertion loss or forward and reverse isolation of the RF network.The 1Z0280-3 also features a high-power capability, allowing it to measure signals up to 10W without distortion or power loss. It also provides a linear response from 50MHz to 6GHz, so that it can accurately measure power levels across a wide range of frequencies.The 1Z0280-3 is an ideal tool for measuring and monitoring RF networks and transmission lines. It provides accurate and reliable measurements of insertion loss, as well as allowing for precise monitoring of power levels in RF environments. It is a cost-effective solution for applications that need reliable and accurate measurement and monitoring of power levels, insertion loss and isolation levels in RF networks.
