Frequency multiplier utilizing composite multiple resonant circuits

Claim 1

A FREQUENCY MULTIPLIER FOR PROVIDING AN OUTPUT SIGNAL AT A HARMONIC FREQUENCY OF AN APPLIED INPUT SIGNAL HAVING A FUNDAMENTAL FREQUENCY COMPRISING: (A) AN ELONGATED CONDUCTIVE ENCLOSURE FORMING A TRANSMISSION LINE OUTER CONDUCTOR; (B) A FIRST ELONGATED CONDUCTIVE MEMBER DISPOSED WITHIN SAID CONDUCTIVE ENCLOSURE, ONE END OF SAID FIRST MEMBER BEING CONDUCTIVELY CONNECTED TO SAID ENCLOSURE AND THE OTHER END BEING BIFURCATED TO FORM ELONGATED SUBSTANTIALLY COEXTENSIVE PARALLEL SPACEDAPART PORTIONS, SAID FIRST MEMBER IN ITS ENTIRETY FORMING AN INPUT TRANSMISSION LINE CENTER CONDUCTOR, SAID PARALLEL SPACED-APART PORTIONS FORMING A FIRST PAIR OF BALANCED TRANSMISSION LINE CENTER CONDUCTORS; (C) SECOND AND THIRD ELONGATED CONDUCTIVE MEMBERS DISPOSED WITHIN SAID CONDUCTIVE ENCLOSURE, SAID SECOND AND THIRD MEMBERS BEING SUBSTANTIALLY COEXTENSIVE PARALLEL AND SPACED-APART TO FORM A SECOND PAIR OF BALANCED TRANSMISSION LINE CENTER CONDUCTORS, SAID SECOND AND THIRD MEMBERS EXTENDING SUBSTANTIALLY COLLINEARLY WITH THE PARALLEL SPACED-APART PORTIONS OF SAID FIRST MEMBER, ONE END OF SAID SECOND AND THIRD MEMBERS BEING CONDUCTIVELY CONNECTED TO SAID ENCLOSURE AND THE OTHER END OF SAID SECOND AND THIRD MEMBERS BEING ADJACENT AN END OF THE PARALLEL SPACED APART PORTIONS OF SAID FIRST MEMBER; (D) FIVE CAPACITORS HAVING ONE TERMINAL CONNECTED TO SAID ENCLOSURE, THE REMAINING TERMINAL OF ONE OF SAID CAPACITORS BEING CONNECTED TO SAID FIRST MEMBER INTERMEDIATE THE CONNECTION OF SAID FIRST MEMBER TO SAID ENCLOSURE AND SAID PARALLEL SPACED-APART PORTIONS FOR TUNING SAID FIRST MEMBER TO BE RESONANT IN QUARTER-WAVE MODE AT THE FUNDAMENTAL FREQUENCY, TWO DIFFERENT ONES OF SAID CAPACITORS HAVING THEIR REMAINING TERMINALS CONNECTED TO SAID PARALLEL SPACEDAPART PORTIONS FOR TUNING SAID FIRST PAIR OF BALANCED TRANSMISSION LINE CENTER CONDUCTORS TO BE RESONANT IN QUARTER-WAVE MODE AT THE HARMONIC FREQUENCY, THE REMAINING TWO OF SAID CAPACITORS HAVING THEIR REMAINING TERMINALS CONNECTED TO SAID SECOND AND THIRD MEMBERS, RESPECTIVELY, FOR TUNING SAID SECOND PAIR OF TRANSMISSION LINE CENTER CONDUCTORS TO BE RESONANT IN QUARTER-WAVE MODE AT THE HARMONIC FREQUENCY; (E) A PAIR OF ELECTRICALLY VARIABLE CAPACITANCE DIODES, ONE OF SAID CAPACITANCE DIODES BEING CONNECTED FROM ONE OF SAID PARALLEL SPACED-APART PORTIONS OF SAID FIRST MEMBER TO SAID SECOND MEMBER, THE OTHER OF SAID CAPACITANCE DIODES BEING CONNECTED FROM THE OTHER OF SAID PARALLEL SPACED-APART PORTIONS OF SAID FIRST MEMBER TO SAID THIRD MEMBER, SAID CAPACITANCE DIODES BEING POLED OPPOSITELY; (F) A SOURCE OF POTENTIAL COUPLED TO SAID CAPACITANCE DIODES AND POLED TO BIAS SAID CAPACITANCE DIODES IN A NONCONDUCTING DIRECTION; (G) AN INPUT LOOP COUPLED TO SAID FIRST MEMBER INTERMEDIATE THE CONNECTION OF SAID FIRST MEMBER TO SAID ENCLOSURE AND SAID PARALLEL SPACED-APART PORTIONS FOR COUPLING AN INPUT SIGNAL INTO SAID ENCLOSURE AND INTO SAID FIRST MEMBER; (H) AND AN OUTPUT LOOP COUPLED TO SAID SECOND AND THIRD MEMBERS AND LOCATED SYMMETRICALLY THEREBETWEEN FOR COUPLING AN OUTPUT SIGNAL OUT OF SAID SECOND AND THIRD MEMBERS AND OUT OF SAID ENCLOSURE.
