Power divider/combiner (DC to 40 GHz)

Power splitters/couplers are components that split the input power of a RF signal to two or more outputs (power splitters) or merge from several inputs into one output (power couplers). Power splitters/couplers are usually the same component, as they must be operated in both directions.
Typically the power split/coupling is equal between input port(s) and output port(s). However, specific power splits are also possible and available.
As the latter mostly involves individual solutions, the probability of finding a product off-the-shelf is correspondingly lower. But this should not be a problem for our customers. With such a wide range of business relationships, it is likely that we would be able to source a comparable component, which can be used for your application and, if not, customer-specific adjustments are our strength.
With normal power splitters all signals on the inputs and outputs are in phase.

In contrast to this, the hybrid coupler allows both a merging and splitting of signal powers, and phasing is shifted between input and output by 90° or 180°, depending on the design. This is because of the hybrid coupler's special construction (see also, hybrid ring). Ultimately the coax hybrid coupler is identical in design to its waveguide equivalent, but its ports are fitted with coax connections.
This also explains why the hybrid coupler is limited in the number of its ports to one input and two outputs. Although it is a 4-port system, only one port is ever the input or output port, and two ports act accordingly as output and input port. The fourth port, however, is isolated from the input port. How the port usage/configuration works depends exclusively on which port(s) are to be operated as input (in the case of power splitter) and/or which as output in the system.
