ABSTRACT:
The present invention relates to a storage device for high-frequency electrical signals.
In the units employed for the storage of electrical signals and consisting of a capacitor in series with a diode constituted by an insulated electrode 10 applied to a semi-conductive substrate marked 3 arranged between the electrodes 2, 5, the invention utilises the piezo-electric substance 40 coupled to a transducer 7 to which they are applied the electrical signals for storage, and a network of diodes applied in the variant embodiment shown in the figure, to said substance and aligned in the direction of propagation of the acoustic waves. Voltage of opposite direction are alternately applied between the electrodes to effect storage and to effect read-out of the signal.
Application to radio frequencies of the order of 100 MHz.
