Hybrid Coupler Basics & Selection

90° Hybrid Couplers

A 90° Hybrid Coupler is a 4 port devices that is used to equally split an input signal with a 90° phase shift between the ports. To illustrate operation, a signal at the input port (port 1) is divided between the two output ports with half the power flowing to the 0° port and the other half flowing to the 90° port. Any reflection from mismatches at the output port flow to the Isolated port (port 4). This is one of the reasons hybrid couplers are used to split signals in applications where unwanted reflections can damage the circuit. This type of coupler is also know as Quadrature coupler.

180° Hybrid Couplers

A 180° Hybrid Coupler is a four port device that is 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. 180° Hybrid Couplers usually consist of a center conductor ring with a circumference of 1.5 times the wavelength (6 times the quarter wavelength). Each port is separated by a quarter wavelength (90° apart). This configuration creates a low loss device with low VSWR and excellent phase and amplitude balance. This type of coupler is also know as “rat race coupler”.

Hybrid Coupler Selection

When selecting a hybrid coupler it is important to know the parameters that you need to specify. The key parameters would be Type, Insertion Loss, Isolation and Power.
