    Abstract: A stable electromagnetic oscillator (30) comprises an amplifying element (3) in feedback association with a dual mode resonant cavity (12) that provides a double pole bandpass filter function. Two orthogonal modes (1 and 2) of electromagnetic energy resonate within the cavity (12). An output from the amplifying element (3) excitationally couples into the first mode (1), while the second mode (2) couples into the input of the amplifying element (3). The output (8) of the oscillator (30) is obtained from the first mode (1). Optional injection lock can be used for greater stability by means of coupling a stable a.c. reference (9) into the cavity (12) in alignment with the second mode (2). Optional electronic frequency tuning comprises a phase or frequency comparator (11) and a reference a.c. source (13), producing a d.c. feedback signal fed to varactor diodes (10). Coupling ports (4, 5, 6, 7) of the cavity (12) can be, e.g., irises, capacitive probes, coaxial probes, or any combination thereof. The electrical field associated with each port (4, 5, 6, 7) is aligned with the electrical field of the mode (1 or 2) coupled thereby. A dielectric resonator (20) can be positioned within the cavity (12) to allow for physical shrinking of the cavity (12) while maintaining the electromagnetic characteristics of the cavity (12).

    Abstract: 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.

    Abstract: A microwave oscillator suitable for millimetre wavelengths comprises a Gunn diode (3) coupled to a wavelength (1) by a resonant-cap structure (5,6). The diode (3) generates microwave energy both at a fundamental frequency f o which is below the cut-off frequency of the waveguide (1) and at a second harmonic frequency 2f o above cut-off. To control the generation of microwave energy at 2f o , energy at f o may be coupled into the waveguide (1), e.g. from an adjacent further waveguide (9) above its cut-off, by means of an electric probe (8) extending close to the cap (5). The probe (8) may couple in a locking signal at or close to the free-running value of f o from another oscillator having better noise performance and electronic tuning, thereby locking 2f o to twice the frequency of the locking signal, or alternatively may couple to a varactor-tuned cavity resonant at f o .

    Abstract: A voltage-controlled oscillator and a method capable of precisely adjusting a frequency shift amount are provided irrespective of a fluctuation in characteristics of elements such as a strip-line. A center tap 19 is formed in a strip-line 16 of a resonator. A switching element 20 is connected to the center tap 19, and this switching element 20 is turned ON, so that the center tap is shortcircuited to the ground so as to vary the oscillating frequency. A slit A1 is conducted in the vicinity of the center tap 19 along the strip-line 16 and directed toward a shortcircuited end 17 of the strip-line, so that a frequency shift amount is adjusted. Also, a slit B1 is conducted in the vicinity of the shortcircuited end 17 along the strip-line 16 and directed toward the center tap 19, so that a frequency shift amount is adjusted. Also, trimming points are provided on the side of a hot terminal 18 from the center tap 19, and also provided on the side of the shortcircuited end 17 from the center tap 19, and further a slit is conducted along an intersecting direction of the strip-line 16, so that a shift amount is adjusted.
