Hybrid coupler.

A 90° Hybrid Coupler is a 4 port device 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 …2. Hybrid Power Splitters: It is use transformers and can provide low levels of loss. While there are some physical losses in the transformer, the major "loss" that arises from the splitting process as the same signal is shared between several outputs. RF Couplers: It separates signals based on the direction of signal propagation.1. Introduction. Hybrid couplers are crucial devices for some HF, VHF and UHF applications such as quadrature combining or power division. Fig. 1 shows the topology of a traditional branch-line hybrid coupler, which is based on a square with two parallel Transmission Line (TL) of a characteristic impedance Z 0 that are perpendicular to the two other transmission lines of Z 0 / 2 [1].KRYTAR's 3 dB, 180-Degree Hybrid Couplers are four-port components with dual input and output ports. The 180-degree hybrids (also referred to as the "rat race" couplers) are four-part devices that are utilized to either equally divide an input signal or to add-up two fused signals. An extra benefit of this hybrid coupler is to alternately ...

Each will typically provide similar port to port isolation, but the Hybrid Coupler/Combiner will handle much more power than a Wilkinson splitter.
