The Hughes 8000 Series of Standard Band Traveling Wave Tube Amplifiers cover the 1 to 40 GHz frequency range with a minimum power output of 10/20 watts CW. Each amplifier consists of a PPM metal-ceramic traveling-wave tube, a regulated solid state power supply and complete air cooling system assembled within a compact instrument case. The 8010/8020's light-weight compactness makes it ideal for either bench or 19-inch rack mounting. This size-weight feature is the result of the unique circuit design. The 8010/8020's have a wide variety of uses in such applications as EMI testing, antenna testing, communications, component testing, system testing and general laboratory requirements.
