FREQUENCY DOUBLER Russian patent published in 2012 - IPC H03B19/00 

FIELD: electricity.

SUBSTANCE: frequency doubler comprises an input transformer, outputs of the secondary winding of which are connected to appropriate inputs of a diode double half-wave rectifier, one output pole of which is connected to one output of the output loading resistor, the other output of this loading resistor is connected to a common bus, i.e. grounded, between a grounded output of the loading resistor, and by the other pole of the diode double half-wave rectifier additionally a resistive-capacitance circuit is connected from parallel connected capacitor and additional resistor, value of resistance of which must be chosen as considerably higher than the value of resistance of the loading resistor, the value of the capacitor capacitance must be selected so that product of this capacitor capacitance by resistance of additional resistor is many times more than period of output oscillations.

EFFECT: reduced duration of output pulses.
