Solid state microwave source utilizing three tuning means

Claim 1

A SOLID-STATE MICROWAVE GENERATOR, COMPRISING: (A) A TRANSISTOR HAVING AN EMITTER, A BASE, A COLLECTOR, AND A LOW COLLECTOR-BASE TIME CONSTANT; (B) A FIRST TUNING MEANS COUPLING SAID BASE TO A POINT OF SUBSTANTIALLY ZERO R.-F. POTENTIAL, SAID FIRST TUNING MEANS BEING ADAPTED TO TUNE THE BASE CIRCUIT INCLUDING SAID BASE AND SAID FIRST TUNING MEANS TO PARALLEL RESONANCE AT A PREDETERMINED FREQUENCY, AND AT THE SAME TIME ADAPTED TO TUNE SAID BASE CIRCUIT TO SUBSTANTIALLY ZERO R.-F. IMPEDANCE AT AT LEAST ONE INTEGRAL MULTIPLE OF SAID PREDETERMINED FREQUENCY; (C) A SECOND TUNING MEANS COUPLING SAID EMITTER TO A POINT OF SUBSTANTIALLY ZERO R.-F. POTENTIAL, SAID SECOND TUNING MEANS BEING ADAPTED TO TUNE THE EMITTER CIRCUIT INCLUDING SAID EMITTER AND SAID SECOND TUNING MEANS TO PARALLEL RESONANCE AT SAID PREDETERMINED FREQUENCY; (D) A THIRD DISTRIBUTED TUNING MEANS COUPLING SAID COLLECTOR TO A POINT OF SUBSTANTIALLY ZERO R.-F. POTENTIAL, SAID THIRD DISTRIBUTED TUNING MEANS BEING ADAPTED TO TUNE THE COLLECTOR CIRCUIT INCLUDING SAID COLLECTOR AND SAID THIRD TUNING MEANS TO PARALLEL RESONANCE AT SAID INTEGRAL MULTIPLE OF SAID PREDETERMINED FREQUENCY; (E) INJPUT TERMINALS FOR APPLYING A FIXED D.-C. OPERATING VOLTAGE TO SAID TRANSISTOR; AND (F) AN OUTPUT TERMINAL COUPLED TO SAID COLLECTOR FROM WHICH SUBSTANTIAL POWER MAY BE DERIVED AT SAID INTEGRAL MULTIPLE OF SAID PREDETERMINED FREQUENCY.
