HUGHES 8000H SERIES
Instrumentation TWT Amplifiers
1.0– 50.0 GHz, 1-70 Watts
FEATURES:
• 30 Models 1-50 GHz, 1-70 Watts • IEEE-488 Data-Bus Interface and other
options available
• Lightweight and compact • Low Spurious Modulation
• High reliability • Automatic Recycle
The Hughes 8000H Series Instrumentation Traveling-Wave Tube Amplifiers are specifically
designed for general purpose system and component testing and laboratory experimentation and
measurement.
The 8000H Series offers power levels of 10, 20 and 30 Watts in the 1 to 18 GHz range, along
with 1 and 10 watt levels between 18.0 and 50.0 GHz. High power narrow band bodels in the
30, 35 and 45 GHz ranges are also available.
Automatic Recycle
This feature automatically recycles the TWTA from ready to “RF on” in the event of a momentary
fault condition such as a power outage of less than 3 seconds, low line voltage, overtemperature,
or helix current overload. In the event of two consecutive helis current overload faults, the
TWTA will revert to the off mode and require manual reset.
