Abstract
The fine protection circuit arrangement is to reduce the remaining residual impulses on gas tube charge eliminators. This is to be achieved by means of a cascading of a gas tube charge eliminator or a .lambda./4 shorting stub with a fine protection circuit. The fine protection circuit connected to the gas tube circuit eliminator or .lambda./4 shorting stub reduces the relatively high residual voltage at the output of the gas tube charge eliminator or .lambda./4 shorting stub to a minimal value.
