Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
136 words
A HIGH FREQUENCY GENERATOR COMPRISING: A RESONANT CAVITY; A STEP RECOVERY DIODE COUPLED TO EXCITE SAID CAVITY; A RESONANT CIRCUIT TUNED TO A FIRST FREQUENCY COUPLED TO SAID STEP RECOVERY DIODE; MEANS FOR EXCITING SAID STEP RECOVERY DIODE AND SAID RESONANT CIRCUIT WITH AN ALTERNATING SIGNAL TO TURN ON AND OFF SAID STEP RECOVERY DIODE, SAID DIODE GENERATING A SIGNAL HAVING HIGH HARMONIC CONTENT AS IT IS TURNED OFF; AND MIXING MEANS INCLUDING SAID DIODE, COUPLED TO SAID RESONANT CIRCUIT AND TO SAID RESONANT CAVITY FOR MIXING SAID HIGH HARMONIC CONTENT SIGNAL AND SAID FIRST FREQUENCY SIGNAL ON SAID RESONANT CIRCUIT AND FOR EXCITING SAID CAVITY WHEN SAID DIODE IS OFF, SAID CAVITY BEING TUNED TO THE ALGEBRAIC SUM OF SAID FIRST FREQUENCY AND AT LEAST ONE OF THE HARMONICS OF SAID HIGH HARMONIC CONTENT SIGNAL.
