Types of Microwave and RF Power Combining Solutions
Microwave Techniques manufactures several different types of high-power microwave and RF waveguide power combiners. With a variety of devices to choose from, we recommend exploring options early in the development of a new system. Additionally, with RF combining playing a key role in system performance and power combiners being a critical instrument within the system, we suggest taking on a partnership with our team to understand the development process of new designs. Efficiency, cost, and space can be optimized with the right attention to the combiner.
In designing robust RF combining systems, understanding the different types of RF devices and waveguide power combiners is critical. Most combiners can be broken down into one of two categories: isolating and non-isolating.
Types of Isolating Power Combiners
- Gysel
- Hybrids
- Wilkinson
- Magic Tees
Types of Non-Isolating Power Combiners
- Tees
- Radial Combiners
- Waveguide Transitions/Combiners
Similarities
- Both will have the same inefficiency during fault conditions
- Neither style combiner will reduce the terminating load VSWR
Differences
- Isolating combiners are typically larger and more expensive
- Isolating combiners will absorb energy due to unbalanced conditions
- Non-isolating will reflect that energy back to the source
