Power Divider Features

• Power dividers can be used as combiners or splitters
• Wilkinson and High isolation power dividers offer high isolation, blocking signal cross-talk between output ports
• Low insertion and return loss
• Wilkinson and resistive power dividers offer excellent (<0.5dB) amplitude and (<3°) phase balance
• Can be used as combiners or splitters

Learn More About Power Dividers

As the name implies, an RF/microwave power divider will split an input signal into two equal and identical (i.e. in-phase) signals. It can also be used as a power combiner, where the common port is the output and the two equal power ports are used as the inputs. Important specifications when used as a power divider include the insertion loss, amplitude and phase balance between the arms, and return losses. For power combining of uncorrelated signals, the most important specification is the isolation, which is the insertion loss from one equal power port to the other.

High Directivity

These circuits are based on a bridge coupler using one of Marki’s world class baluns, providing the highest possible isolation across a massive broadband covering from kHz to GHz frequencies. These are ideal for power combining uncorrelated signals. Their higher insertion loss and uncontrolled phase balance makes them unsuitable for power dividing applications, typically.

Wilkinson 1:2

A Wilkinson power divider offers the lowest insertion loss (ideally 3 dB, or just the splitting loss) from DC to very high bandwidths. It will also offer isolation across a narrower bandwidth. Marki Wilkinson power dividers offer isolation across extremely broad bandwidth ratios, up to 65:1. As discussed in our tech notes, the required specifications and capabilities for a Wilkinson for power handling and isolation can vary dramatically depending on the application. See our tech notes or contact Marki for further information or to discuss your specific application.

Wilkinson 1:3

Marki offers unique 1:3 Wilkinson power dividers based on advanced circuit analysis techniques. While three way Wilkinson power dividers are theoretically easy to design, they are very difficult to realize due to the impedances necessary. Extensive experimentation and analysis have allowed Marki to realize 1:3 Wilkinsons across broad bandwidths.

Wilkinson 1:4

Marki 1:4 Wilkinsons are realized as a cascade of two 1:2 Wilkinson power dividers. By integrating them together into a single package, Marki is able to optimize the interconnects for minimum insertion and return loss.

Resistive 1:2

A resistive power divider is the smallest, simplest, and most broadband type of power divider. However, due to the high insertion loss and lack of isolation it is rarely the best choice for a given application over a Wilkinson power divider. See our tech notes or contact Marki for further information.
