How to Specify Power Dividers
There are a few pertinent parameters that you need to know in order to specify a power divider properly.
- Number of ways
This parameter defines how many output ports that an RF signal gets routed to after passing through the power divider. For example, a 4-way power divider will split an incident RF signal into 4 equal outputs. In theory, you can split an RF signal into as many different paths as you want. The common number of output ports are as follows:
2-way power divider / power combiner
3-way power divider / power combiner
4-way power divider / power combiner
5-way power divider / power combiner
6-way power divider / power combiner
8-way power divider / power combiner
12-way power divider / power combiner
16-way power divider / power combiner
- Frequency of operation
You need to let the manufacturer know what is the frequency of operation for the n-way power divider/combiner. You could classify it by band, for example, L-Band power divider. Or you could specify the exact operating frequency of the power divider or the power divider bandwidth.
For example, you could mention that you need the power divider to operate from 700MHz to 2.7 GHz.
- Type of Connector
You could request for N-type connectors for your power divider or you could specify SMA-connectors.
- Mechanical constraints
If you have size limitations or need us place the connectors of the power divider in a particular fashion, please let us know and we will study the feasibility of doing so.
There are other parameters like port-to-port isolation for power divider and amplitude and phase balance among ports. Unless there are some essential requirements, there is usually no need to specify these.

Applications for Power Dividers and Power Splitters
In radio technology, you’ll see many devices used to distribute, combine, or else transport power in some form to various places that need it. Power splitters are among these devices, being passive devices that use a single input signal and then deliver two or more output signals. Power splitters are usually used in ratio measurements and in source levelling.
If you’re new to the field, however, some of these terms may confuse you. For instance, are power splitters and power dividers interchangeable? Going by the names alone, you’ll be inclined to think that they are. However, ask any power splitter combiner supplier Singapore and you may be surprised to hear that they’re not entirely interchangeable.
To help you avoid misusing one or the other, here’s a brief look at the differences in application for either device.
These devices are RF accessories that provide 50Ω (ohm) resistance at each of its three ports – one for input and two for output. As the name suggests, it’s used to divide power equally between the two output ports to enable comparison measurements.
This device can also be used to measure two different characteristics of a signal – power, for instance, as compared to frequency. Because all three ports have the same resistance, this component is bi-directional, therefore able to act as a power combiner should the signals be reversed.
Another application for power dividers is in measuring diversity gain – the increase in the ratio of signal to interference when two or more communication channels are used to strengthen signals.
These devices are typically constructed of two resistors – passive components that reduce current flow and lower voltage levels within circuits. Such a configuration usually results in only the input port having an impedance of 50Ω (ohm). Some splitters, though, have equal impedance at all three ports (similar to the divider) to lessen measurement uncertainty when it comes to source levelling.
This then means that only certain splitters can be used as power combiners. For one thing, the different impedance measurements at each port will result in a drop in output. This can interfere with comparison measurements and the like.
As such, power splitters are often used to measure gain, compression, and isolation – in addition to rationing and source levelling. In a set-up to test for amplifier gain, the power splitter removes re-reflected signals so that measurements can be taken at different RF power levels. This saves time on the procedure because the technician won’t need to re-calibrate for each power level.
So what does this all mean? Though power splitters and dividers perform similar functions, they’re not always interchangeable – it depends on what you need for your test system. So look at that first before deciding which splitter or divider to get.
