Abstract
A rectangular electrical pulse enters a transmission line structure with single pass transit time equal to ½ the duration of the pulse, open circuit at the extreme end and a switch at its center. After a delay equal to ¾ of the rectangular pulse duration the central switch is closed to couple the contents of the transmission line structure into another transmission line of half impedance. The output pulse maintains the initial voltage, but is of half the initial duration, and double the initial power.
Claims7
A compressor circuit comprising two transmission lines AB and BC each of round trip transit time τ/2 and impedance Z connected to each other at point B with end C open circuit, and a switch S connecting point B to an output transmission line or load of impedance Z/2, wherein:
- with switch S open, a rectangular pulse of voltage V and duration τ enters the compressor at point A and propagates within the compressor for a time 3τ/4 after which switch S closes to connect point B to the output transmission line or load, generating a pulse of voltage V and duration τ/2 therein.
