An electronic gate circuit is described which has better than 1% linearity for pulses in the range 1 to 70 volts. The circuit gives an inverted output with a gain very close to unity and accepts positive inputs. The leakage of a 70‐volt pulse through the closed gate is 0.6 volt and the largest negative going portion of the gating transient is 0.2 volt. The gate can be reliably opened with positive trigger pulses in the range 4 to 9 volts and the time jitter over this range is the same as the rise time of the trigger pulses. The inherent rise time of the gate output is about 50 millimicroseconds.
