Application Notes: Power Dividers

Werbel Microwave designs, develops and manufactures its own line of power dividers splitters combiners in a variety of technologies.  This allows us to support the product indefinitely.  All of our products are backed by a one year warranty.

Power dividers are important components in communications networks. At the end of the day, wireless signals must be distributed on some sort of physical medium such as coaxial cable. Werbel Microwave dividers are available in a variety of configurations and frequencies, from 2 to 32 outputs.  From several MHz to 20 GHz.

Divider types are available in the following technologies.  Each has their own advantages and disadvantages, depending on the application.

How well the output port paths are isolated from each other will depend largely on the technology used.  Isolated outputs is important in applications in which a failure or open circuit on one part would have catastrophic consequences on adjacent networks.

Wilkinson Dividers

Wilkinson dividers are commonly used from a few hundred MHz to several GHz.  They offer low insertion loss, and high isolation over a wide bandwidth.  These are available in both microstrip and stripline.  Werbel Microwave prefers stripline for higher performance at frequencies above 6GHz, while microstrip at lower frequencies helps us offer a performance product at a competitive price.

Resistive Dividers

Resistive dividers offer extremely wide bandwidths down to DC at the expense of higher insertion loss and lower isolation.  The insertion loss of an N-way resistive splitter is double that of an N-way Wilkinson.  This makes the suitable for lower power applications, where gain blocks may be added elsewhere in a system.

Ferrite and coax dividers

Variations of Wilkinson dividers that use inductive elements in place of printed transmission lines.  The main reason for this is to achieve performance at frequencies below about 300 MHz, where printed transmission line lengths become impractically long.  The disadvantage is the high frequency cutoff of about 2 GHz.

Reactive splitters

Reactive or "resistorless" dividers are a way to distribute high power signals with minimal risk of damage to the product.  These units are used for splitting power, and are capable of handling hundreds of watts, as there is no resistive element to concern with dissipating power.  Of course, the disadvantage is the lack of isolation between outputs, which must be accounted for elsewhere in the system.
