Unidirectional amplifier consisting of concatenated bidirectional negative resistance amplifiers which are coupled by delay networks and energized sequentially

Claim 1

A UNIDIRECTIONAL AMPLIFIER COMPRISING, AMPLIFICATION MEANS COMPRISING NEGATIVE RESISTANCE CIRCUITS AND DELAY CIRCUITS HAVING THE SAME DELAY TIME, MEANS CONNECTING SAID CIRCUITS ALTERNATELY IN CASCADE, EACH OF SAID NEGATIVE RESISTANCE CIRCUITS HAVING A NEGATIVE RESISTANCE CHARACTERISTIC AND CAPABLE OF AMPLIFYING AN INPUT SIGNAL ONLY WHEN EACH OF SAID NEGATIVE RESISTANCE CIRCUITS IS EXCITED BY AN EXCITING PERIODIC POWER SIGNAL HAVING A DURATION EQUAL TO THE DELAY TIME OF SAID DELAY CIRCUITS AND A DELAY BETWEEN PERIODS EQUAL TO AN INTEGRAL MULTIPLE OF THE DELAY TIME OF SAID DELAY CIRCUITS, SAID NEGATIVE RESISTANCE CIRCUITS COMPRISING MEANS ATTENUATING AN INPUT SIGNAL DURING SAID DELAY BETWEEN PERIODS OF SAID EXCITING SIGNAL, AN EXCITING POWER SOURCE MEANS CONNECTED FOR APPLYING A PLURALITY OF SAID EXCITING PERIODIC POWER SIGNALS WHICH HAVE THE SAME DURATION AND THE SAME DELAY BETWEEN PERIODS RESPECTIVELY AND HAVE A PHASE DIFFERENCE EQUAL TO THE DELAY TIME OF SAID DELAY CIRCUITS SUCCESSIVELY, SAID SIGNALS EQUALING IN NUMBER A NUMBER WHICH IS EQUAL TO THE NUMBER OF SAID NEGATIVE RESISTANCE CIRCUITS, WHEREBY A SIGNAL TRAVELLING IN AN AMPLIFICATION DIRECTION IS AMPLIFIED EACH TIME WHEN THE TRAVELLING SIGNAL PASSES THROUGH SAID NEGATIVE RESISTANCE CIRCUITS, AND ANOTHER SIGNAL TRAVELLING IN AN OPPOSITE DIRECTION TO SAID AMPLIFICATION DIRECTION IS ATTENUATED EACH TIME WHEN THE OTHER SIGNAL HAS PASSED THROUGH EACH OF SAID NEGATIVE RESISTANCE CIRCUITS.
