Splitters And Dividers
The fundamental difference between power splitters and power dividers (combiners) is the resistor configuration used to separate the power. … The two-resistor configuration of the 11667A and 11667B provides a 50 Ω output impedance to minimize uncertainty in these applications.
Splitters may be small, but they are powerful little pieces of equipment, especially when you need to manipulate your input/output configuration. In fact, one of the first things checked when audio or video gets frozen is the point when cables are connected to appliances. Depending on how you have your equipment set up, however, it may take some time to identify the faulty components.
Splitters, Dividers, and Combiners
Although these devices often look the same and have similar forms of operation, there are a few types of splitters and combiners:
RF (or radio frequency) splitters do what their name says: they split the incoming signal. Sometimes, this component is called an RF divider.
Power splitters or dividers accept power and then divert it toward two or more destinations.
RF combiners combine multiple frequencies into a single line of feed. When this happens, the level of power leaving the output port is the same as the sum of the two input levels.
You need to be familiar with the various options in order to choose the component that will work best for your setup.
Power dividers (also power splitters and, when used in reverse, power combiners) and directional couplers are passive devices used mostly in the field of radio technology. They couple a defined amount of the electromagnetic power in a transmission line to a port enabling the signal to be used in another circuit.
