POWER DIVIDERS/PHASE SHIFTERS
Our Power Dividers utilize the three-hybrid method to provide continuously variable division of input power from insertion loss to –30dB. Power may be split between the output ports in any desired ratio. One of the outputs of the Power Divider may be equipped with a phase shifter, as shown here, to provide two outputs that are continuously variable in both power and relative phase up to 360 degrees.
The Power Divider and Phase Shifter can be provided as separate units or as an integrated assembly. Models are available for use with vacuum waveguide and for pressurized waveguide.
This type of power divider and phase shifter is inherently narrow band in operation and we can provide units for all popular accelerator frequencies as well as other frequencies from 1 GHz to 18 GHz to meet your specific requirements. These devices are capable of extremely high power handling. Units have been built to handle up to 40 MW peak and 100 kW average in S-Band. For high average power applications, water cooling is required.
These units may be mounted in any position and can be provided with waveguide bends or extended straight sections on any or all of the four ports to integrate easily into your RF system. In addition, we can provide units with directional couplers on any of the ports to monitor power input, output and reflected power.
Manual adjustment of power division and phase is standard. Remote adjustment using an analog controlled motor or a stepping motor is also available. When equipped with a fast stepping motor very fast changes in power division and phase can be made. Rates of change exceeding 1 degree per millisecond have been achieved.
