Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
108 words
An oscillator comprising, in combination; a housing having a resonating cavity; a solid state mechanically tuneable element adjustably disposed in said housing extending concentrically through said resonating cavity, and capable of producing a wave form energy output of a frequency relative to its position in said resonating cavity; a solid state electronically tuneable element in circuit with and arranged and disposed concentrically with the mechanically tunable element; position adjustment means exterior of said housing operably connected to said mechanically tuneable element; mechanical connecting means between the mechanically tunable element and said position adjustment means; and electrical bias sources operably connected respectively to each of the said tuneable elements.
Claim 2
Dependent Claim
108 words
An oscillator comprising, in combination; a housing having a resonating cavity; a solid state mechanically tuneable element adjustably disposed in said housing extending concentrically through said resonating cavity, and capable of producing a wave form energy output of a frequency relative to its position in said resonating cavity; a solid state electronically tuneable element in circuit with and arranged and disposed concentrically with the mechanically tunable element; position adjustment means exterior of said housing operably connected to said mechanically tuneable element; mechanical connecting means between the mechanically tunable element and said position adjustment means; and electrical bias sources operably connected respectively to each of the said tuneable elements.
Claim 3
Dependent Claim
40 words
An oscillator according to claim 1 wherein said mechanical connecting means between the mechanically tuneable element and said position adjustment means is a coaxial cable component, the conductors of which respectively carry the electrical biases to the said tuneable elements.
