Mega industries produces custom designed, coaxial power combiners for most any application.
Our three main types of Power Combiners are Impedance, Hybrid and Gysel.
Learn about our three main types of Power Combiners:
Essentially these are multi-port power splitters used in reverse to combine multiple inputs that are in-phase and of equal amplitude. This type of combiner offers no form of isolation between inputs in that if there is an imbalance of either phase or amplitude, there will be significant power reflected back towards the input source. There are no loads in this device and as long as the inputs are equal power and phase, this form of combining is very efficient and cost effective.
Hybrid Network Combiner
Using a corporate, or linear arrangement of 4-port hybrids, multiple inputs can be combined to a single output. This type of combiner can have multiple inputs of different amplitude and/or phase and offer the feature that the input port will always present a matched load, no matter the state of the other input sources. The loads present on the “isolation” port of the each hybrid absorbs the imbalance portion of the source power. The insertion loss of this traditional type of power combining tends to be the highest of three types.
Like the impedance combiner, multiple input sources can be combined in a low insertion loss manner. However, our Coaxial Gysel Combiners include an additional network structure to provide isolation much in the same manner as the hybrid network, but in a very compact system. This system requires one load per input that does not see any power unless there is an unbalance in the amplitude or phase of the sources. Additionally, the loads need only be rated to approximately 75% of a single input source, contrary to the hybrid combiner, where the load rating needs to commensurate with the actual power present in that particular hybrid.
Mega Industries manufactures a comprehensive line of coaxial transmission line and components in sizes from type N through 14-inch diameter. Copper and aluminum alloy tubes are available for outer conductors and high conductivity copper tubes are utilized for inner conductors. Teflon line supports are used in standard transmission line and rexolite or ceramic supports are available for special applications.
In addition to coaxial power combiners, other coaxial products such as 45- and 90-degree miter bends, special angle bends, directional couplers, impedance transformers, impedance matchers, tee junctions, hybrid couplers, phase shifters, attenuators, and coaxial accessories are available to complete your systems.
All Mega Industries coaxial power combiners are manufactured to exacting electrical and mechanical tolerances to provide maximum stability and minimum VSWR.
