MDL variable power dividers are widely used in resonant rings, and can serve as attenuators, particularly where high power is involved. Their peak power handling capacity (without additional pressure) ranges from 18KW in WR28 to 2.5MW in WR284. For applications requiring high average power, provisions can be made for water cooling. The power division is not inherently linear with frequency: however, calibrations can be supplied for specified frequencies. All models may be modified mechanically or electrically to meet customers’ special requirements.
