Nautel believes our technology is the best in the world

• DC to RF power conversion efficiencies between 94 and 98%

• Totally Solid State offering significant operational benefits incomparison to vacuum tube technology

• Precise digital control of operating frequency and power levels.

• Safe operating area protection allows wider range of operating impedance levels and improved reliability

• Continuous digital measurement of RF impedance and power levels.

• Custom high performance control algorithms may be implemented with relative ease using DSP based technology.

• Air and water cooled applications.

Technology Leadership


.

Operational benefits of solid state amplifiers include:

• Highest reliability

• Soft failure modes

• No wear-out mechanisms

• Reduced on-site technical support

• Amplifiers without frequency selective parts allows instant frequency change with acceptable impedance matching

• 1 to 4 dollars per watt range depending on frequency and other system requirements.
