High Energy Devices’ Power Gaps consist of two metal electrodes hermetically sealed in a gas filled rugged ceramic cylinder. The coaxial electrode system of these devices is designed to handle high energy pulses. The Power Gap is used to protect signal and power lines from transients generated by sources such as lightning and other electro-magnetic impulses. Applications are found in avionics, military, industrial and medical equipment. |

High Energy Devices' Uni-Imp Series provides the
ultimate in surge protection from high energy, fast rising transients.
These devices are constructed using a proprietary semiconductor
junction process which results in nanosecond response times combined
with peak current ratings in the 5,000-10,000 ampere range. A unique
benefit of this technology is that the breakdown voltage is virtually
independent of the rise time of the transient. In addition, the
low capacitance of these devices allows direct placement on high
frequency lines and antenna feeds without excessive loading. Applications
are found in military, industrial and medical equipment. |

High Energy Devices’ Spark Gaps are designed
for a wide variety of applications requiring the efficient transfer
of high voltage, high energy pulses. Typical applications include
overvoltage protection of magnetrons, diodes, capacitors, and other
components in high voltage circuits and as switching devices in
pulse generating circuits. High Energy Devices’ miniature
spark gaps have been designed for applications that have severe
environment and high reliability requirements and where cost is
a major consideration. |

High Energy Devices’ Triggered Spark Gaps, which have main static breakdowns up to 60kVdc, are high energy spark gaps which are capable of switching stored energy in a fraction of a microsecond upon command. Triggered Spark Gaps require no standby power, are extremely rugged and require only a low energy, high voltage pulse. Applications include crowbars, exploding bridge wire systems, and xenon flashlamp triggers. High Energy Devices’ miniature Triggered Spark Gaps, which have main static breakdowns between 2.0 and 10.0kVdc, have been designed for applications where cost is a major consideration, but high reliability switching is still required. |

High Energy Devices’ gas discharge source is the element
in a microwave RF system that makes possible accurate measurements
of the noise figure of the receiver or its components. The requirements
of a device used for making such noise figure measurements include
broad bandwidth inherent in the active element, stability, ease
of operation and long life. When the gas discharge noise tube is
mounted and terminated normally, it presents a “white signal”
of constant intensity over a bandwidth limited only by the system
or mount. In general, the range of usefulness of these noise sources
permits measurements of noise figures from about 2 to 30db. Existing
mountings provide a useful frequency range of approximately 100MHz
to 100GHz. |
