Description

Barth High Voltage pulse attenuators are matched impedance coaxial attenuators for use primarily in pulsed 50 ohm systems, or where occasional transients would damage ordinary units.

  • input impedance very close to 50 ohms
  • as good or better than most microwave attenuators.
  • ideal for use in nuclear and high energy experiments.

Extensive testing during manufacturing insures very high reliability for single-shot experiments.  A voltage coefficient of the resistive film of less than .0001%/V allows low voltage calibration of most systems.

Advantages over standard RF Attenuators:

– Low reflection coefficient
– Withstands high voltage pulses
– Pulse power rated
– Low voltage coefficient
– High reliability
– Input/Output impedance held very close to nominal

** Any male or female (GR, N, HNB, GHV) can be supplied

* Unit is supplied with a Barth Model 404-HMM low reflection HNB male to male adapter, so that either the input or output can be adapted to a male connection

NOTE: Our type HN (HNB) connectors are specially designed to obtain minimum reflection coefficient for fast risetimes.  For best pulse response, our model 401-HNB male or 402-HNB female cable connector for RG213/214 coax should be used for interconnection
