General Overview

Ciao Wireless features a full product line of Radial Power Combiners and Radial Power Dividers from frequency ranges that begin at UHF up through KU-Band, with N-Way options available from 4:1 through 90:1. 

With today’s demands for increased power levels in all applications, whether it be EW/ECM, Contemporary Radar and Phased Arrays, and Communications Systems, the Radial Power Combiners/Dividers offered by Ciao can provide the commercial, technical, and reliability solutions required in order to meet any program needs.

​While Ciao offers a broad variety of catalog models, most units are built and fully customized to meet the individual customer's unique requirements.

Technical and Commercial Advantages

Radial Power Combiners and Dividers offer many advantages to the customer. These advantages include:

• Ultra-Low Insertion Loss
• Graceful Power Degradation versus TWT
• Apmlitude and Phase Stable

Hot Replacement

Radial Power Combiners and Dividers allow an amplifier system to remain on the air should one or more amplifier modules fail. And, “hot replacement” of failed amplifiers is permitted while the system remains in operation, assuming that the customer has the appropriate equipment available to accommodate this action. In addition,  RPC/RPD’s are tolerant to amplifier phase and amplitude mismatches, of which, the effects can be accurately simulated.

Proven Design Techniques

Ciao Wireless Radial Power Combiner/Divider units are N-Way, in-phase, non-resonant radial transmission line structures. They combine or divide in a single step.  This means that Ciao’s RPC/RPD units have inherently lower losses than those of corporate structures such as binary trees of Wilkinson combiners. In addition, and unlike most corporate combiners, Radial Combining orders NEED NOT BE BINARY multiples. Ciao utilizes an air-dielectric and purely reactive design. Ciao does not use mode suppressors or isolation resistors, thereby avoiding topology interference, heat-sinking problems, and associated losses. All units are precision machined and feature field replaceable connectors. The design, although simple, but rugged, is made to perform within and withstand harsh environments.

Flexible Configuration and Packaging ​

Ciao’s design flexibility allows for a wide variety of packaging, mounting and connector configurations, including “Combined-Stacked” units in which the RPC and RPD are integrated within the same housing, reducing overall size (as seen in the photo to the left).  While most of Ciao’s designs are customer, all are developed around standard and previously developed design concepts, in order to meet specific electrical, mechanical, and environmental requirements. Isolators can be easily integrated into Ciao’s RPC/RPD units.
