摘要: A resonator (5) includes a substrate (15) to which are attached trimmable capacitance (31, 32A) and inductance (37, 38) portions which together with a varactor (7) and transistor (8) form an oscillator circuit. The resonator (5) mounts orthogonally in a slot (10) on an oscillator board (9) to reduce microphonic effects from a cover (6) that otherwise would degrade the oscillator performance.

摘要: A resonator (5) for a high frequency electric oscillator is disclosed. The resonator is an integrated capacitor and inductor. The capacitance (9) and inductance (10) of the resonator are continuously and simultaneously adjustable (26). The resonator includes a coaxial portion and a conductor portion. The coaxial portion has an inner dielectric (13) with a longitudinal aperture (14) and an outer conductive sheath or outer conductor (12). The conductor portion has a straight section (18) slidable in the aperture (14) and a V-shaped bent or oblique section (10).

摘要: An oscillator voltage regulator includes a substantially constant voltage device (D1) in series with the bias network dividing resistors (R1 & R2) to reduce current flow and provide a substantially constant voltage drop, and an impedance (R3) connected between the first and second resistors of the dividing resistors (R1 & R2) and the tank circuit (T) and the base of the amplifier transistor (A) so as to reduce the loading on the tank circuit and so as to improve stability, reduce phase noise, and increase power output from the amplifier. The use of silicon PN junction (D1) and a NPN transistor (A) provides temperature compensation for hot and cold ambients to allow the oscillator to operate substantially a constant supply current (I4).
