Product Description

Key Features

Low loss: This is the biggest advantage. Waveguide transmission loss is much lower than that of coaxial cable and microstrip line, resulting in a very low insertion loss in the combiner.

High power handling: Due to its hollow structure, there is no easily broken center conductor, allowing it to withstand very high power and is commonly used in high-power radar systems.

High isolation: A well-designed combiner ensures that the signals between its two input ports are "invisible" to each other, resulting in high isolation and preventing signal interference.

Large size and high cost: Compared to PCB-based microstrip combiners, precision-machined metal waveguide combiners are bulkier and more expensive.


Waveguide combiners are commonly used in applications requiring extremely high performance and power:

Radar systems: Especially high-power and weather radars, which require combining the power of multiple transmitters.

Satellite communications: Used in ground stations and satellite payloads to combine signals from different beams or channels.

High-energy physics: Applications such as particle accelerators require high-power microwave sources.

Test and measurement systems: As part of high-end test equipment, they are used for signal combination and separation.
