Description
RF/microwave couplers are passive coaxial devices that are used to sample high frequency signals. Couplers take one signal as the input and supplies two outputs. One output is the regular output and the other one is the coupled output. The power level of the coupled signal can be specified according to the required application. RF couplers are used in a broad range of applications, including power monitoring, antenna reflection monitoring, automated gain control, test & measurement, and much more. The key parameters of couplers include type, frequency, insertion loss, isolation, and power.
Types of couplers and hybrids
Directional couplers are four-port devices with an input and output port, a port for the coupled signal and a port that is terminated internally. Directional couplers sample signal from the main line in forward direction.
Bi-directional couplers have two coupled ports to sample signal from the forward or reflected signal paths as needed.
Dual directional couplers allow simultaneous sampling of both thru- and reflected signal power.
90° Hybrid couplers are four-port devices that are used to equally split an input signal with a 90° phase shift between the ports.
180° Hybrid couplers are four-port devices that are used either to equally split an input signal with a 180° phase shift between the ports or to combine two signals that are 180° apart in phase.
