UHF WATER COLUMN LOADS

P-Cube's family of water loads gives the end user the lowest price-to-kW ratio design available for the UHF market.  The load combines the lossy element and the load coolant as a single unit, eliminating the fragile resistor which is normally cooled by a liquid in direct contact with a resistive element.  

The loads are extremely rugged since the resistor is liquid and no finger contacts are used.  A dielectric transformer on the inner conductor distributes power evenly throughout the coolant.  This provides exceptional thermal stability over a wide range of temperature and power levels.  Each load has a low VSWR across the UHF band.  Units can be tuned to a specified UHF channel to approximately a 1.05 VSWR.
