Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
151 words
A CONVERTER FOR MIXING AN INPUT SIGNAL OF A FIRST FREQUENCY WITH AN OSCILLATOR SIGNAL OF A SECOND FREQUENCY AND DEVELOPING A RESULTANT OUTPUT SIGNAL OF A THIRD FREQUENCY COMPRISING: (1) A TRANSISTOR HAVING BASE, EMITTER, AND COLLECTOR ELECTRODES, (2) INPUT MEANS FOR APPLYING A SIGNAL OF SAID FIRST FREQUENCY TO SAID EMITTER, (3) OSCILLATOR FREQUENCY-DETERMINING MEANS CONNECTED TO SAID COLLECTOR FOR DEVELOPING A SIGNAL OF SAID SECOND FREQUENCY, (4) OUTPUT MEANS DIRECTLY CONNECTED TO SAID COLLECTOR FOR DEVELOPING A RESULTANT OUTPUT SIGNAL OF SAID THIRD FREQUENCY, (5) BLOCKING MEANS CONNECTED TO SAID COLLECTOR AND CONNECTED BETWEEN SAID OSCILLATOR FREQUENCY-DETERMINING MEANS AND SAID OUTPUT MEANS FOR BLOCKING SAID RESULTANT OUTPUT SIGNAL AND ISOLATING SAID OUTPUT MEANS FROM SAID OSCILLATOR FREQUENCY-DETERMINING MEANS, (A) SAID OSCILLATOR FREQUENCY-DETERMINING MEANS BEING CONNECTED TO SAID COLLECTOR THROUGH SAID BLOCKING MEANS, AND (6) REGENERATIVE FEEDBACK MEANS CONNECTED BETWEEN SAID EMITTER AND SAID COLLECTOR THROUGH SAID BLOCKING MEANS.
