Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
82 words
A TRANSISTORIZED CIRCUIT COMPRISING (A) FIRST AND SECOND TRANSISTORS EACH HAVING FIRST, SECOND, AND THIRD ELECTRODES, (B) MEANS COUPLING THE FIRST ELECTRODES OF SAID FIRST AND SECOND TRANSISTORS TO A COMMON REFERENCE POINT, (C) A SERIES RESONANT CIRCUIT COUPLED BETWEEN THE SECOND ELECTRODES OF SAID FIRST AND SECOND TRANSISTORS, (D) MEANS FOR COUPLING AN INPUT SIGNAL VOLTAGE IN SERIES WITH SAID SERIES RESONANT CIRCUIT, AND (E) MEANS FOR COUPLING THE THIRD ELECTRODES OF SAID FIRST AND SECOND TRANSISTORS TO AN OUTPUT TERMINAL.
Claim 2
Dependent Claim
82 words
A TRANSISTORIZED CIRCUIT COMPRISING (A) FIRST AND SECOND TRANSISTORS EACH HAVING FIRST, SECOND, AND THIRD ELECTRODES, (B) MEANS COUPLING THE FIRST ELECTRODES OF SAID FIRST AND SECOND TRANSISTORS TO A COMMON REFERENCE POINT, (C) A SERIES RESONANT CIRCUIT COUPLED BETWEEN THE SECOND ELECTRODES OF SAID FIRST AND SECOND TRANSISTORS, (D) MEANS FOR COUPLING AN INPUT SIGNAL VOLTAGE IN SERIES WITH SAID SERIES RESONANT CIRCUIT, AND (E) MEANS FOR COUPLING THE THIRD ELECTRODES OF SAID FIRST AND SECOND TRANSISTORS TO AN OUTPUT TERMINAL.
Claim 3
Dependent Claim
155 words
AN AMPLIFIER COMPRISING (A) FIRST AND SECOND TRANSISTORS EACH HAVING AN EMITTER, BASE AND COLLECTOR ELECTRODE, THE EMITTER ELECTRODES OF SAID FIRST AND SECOND TRANSISTORSD BEING CONNECTED TOGETHER, (B) A PAIR OF INPUT TERMINALS, (C) A SERIES RESONANT CIRCUIT TUNED TO THE FREQUENCY OF A SIGNAL APPLIED ACROSS AND SAID INPUT TERMINALS, AND SERIES RESONANT CIRCUIT COMPRISING A CAPACITOR HAVING ONE TERMINALS CONNECTED TO THE BASE ELECTRODE OF ONE OF SAID TRANSISTORS AND A TRANSFORMER HAVING ONE WINDING CONNECTED BETWEEN THE OTHER TERMINAL OF SAID CAPACITOR AND THE BASE ELECTRODE OF SAID OTHER TRANSISTOR, SAID TRANSFORMER FURTHER HAVING A PRIMARY WINDING CONNECTED BETWEEN SAID PAIRS OF INPUT TERMINALS, (D) AN OUTPUT PARALLEL RESONANT CIRCUIT COUPLED BETWEEN THE COLLECTOR ELECTRODES OF SAID FIRST AND SECOND TRANSSISTORS, SAID PARALLEL RESONANT CIRCUIT BEING TUNED TO THE FREQUENCY OF THE SIGNAL APPLIED ACROSS SAID INPUT TERMINALS, AND (E) A PAIR OF OUTPUT TERMINALS COUPLED TO SAID OUTPUT RESONANT CIRCUIT.
Claim 4
Dependent Claim
155 words
AN AMPLIFIER COMPRISING (A) FIRST AND SECOND TRANSISTORS EACH HAVING AN EMITTER, BASE AND COLLECTOR ELECTRODE, THE EMITTER ELECTRODES OF SAID FIRST AND SECOND TRANSISTORSD BEING CONNECTED TOGETHER, (B) A PAIR OF INPUT TERMINALS, (C) A SERIES RESONANT CIRCUIT TUNED TO THE FREQUENCY OF A SIGNAL APPLIED ACROSS AND SAID INPUT TERMINALS, AND SERIES RESONANT CIRCUIT COMPRISING A CAPACITOR HAVING ONE TERMINALS CONNECTED TO THE BASE ELECTRODE OF ONE OF SAID TRANSISTORS AND A TRANSFORMER HAVING ONE WINDING CONNECTED BETWEEN THE OTHER TERMINAL OF SAID CAPACITOR AND THE BASE ELECTRODE OF SAID OTHER TRANSISTOR, SAID TRANSFORMER FURTHER HAVING A PRIMARY WINDING CONNECTED BETWEEN SAID PAIRS OF INPUT TERMINALS, (D) AN OUTPUT PARALLEL RESONANT CIRCUIT COUPLED BETWEEN THE COLLECTOR ELECTRODES OF SAID FIRST AND SECOND TRANSSISTORS, SAID PARALLEL RESONANT CIRCUIT BEING TUNED TO THE FREQUENCY OF THE SIGNAL APPLIED ACROSS SAID INPUT TERMINALS, AND (E) A PAIR OF OUTPUT TERMINALS COUPLED TO SAID OUTPUT RESONANT CIRCUIT.
