Barth 2238 Series 350MHz Attenuators

Barth 2238 Series 350MHz Attenuators



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

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

Extensive testing during manufacturing ensures 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
