FOOD PREPARATION
Inexpensive magnetrons
are used by the millions  in microwave ovens.

FUSION
Megawatt gyrotrons
are being developed​
for science applications.
DEFENSE
Thousands of crossed-field amplifiers are used in Navy AEGIS systems.

RADAR & SCIENCE
Megawatt klystrons
are used in radars and accelerators.
  • Klystrons have produced > 1 GW pulsed at S-band and 1 MW CW at X-band.

  • Microwave tubes are reliable. (A traveling wave tube on the Voyager 1
       satellite was still operating after 37 years in orbit. That tube was the backup for
       the solid state transmitter which failed shortly after launch). Traveling wave
       tubes are the amplifiers of choice for most satellite applications.

  • Industrial magnetron efficiencies exceed 80%. Satellite traveling wave tube efficiencies exceed 70%

  • Because they can operate at High temperatures with high efficiency, tubes can be smaller and lighter than solid state devices and still eliminate waste heat.

COMMUNICATIONS
DIRECTTV satellites use nearly 100
traveling wave tubes.
