A proximity fuse for high trajectory weapons, comprising a ram air driven generator generating the supply voltage to the electronic circuit elements of the proximity fuse which control the proximity functions of the fuse. The supply voltage from the generator is blocked at decreasing frequency, whereas the blocking is terminated at increasing frequency. Elements for blocking the electronic circuit comprise a differential amplifier to which a top rectified generator voltage is supplied, and the amplifier has a larger gain in the range where the generator voltage changes from a decreasing to an increasing value.
