    摘要: Power amplifiers with injection-locked oscillator are provided. In certain configurations, a packaged module includes a package substrate, a semiconductor die attached to the package substrate and having a power amplifier formed thereon, and an output matching network attached to the package substrate and operable to provide output impedance matching to an output of the power amplifier. The power amplifier includes two or more stages electrically coupled between the input and an output, and the two or more stages include an injection-locked oscillator stage that receives a radio frequency input signal and generates an injection-locked radio frequency signal.

    摘要: An element which oscillates or detects terahertz waves includes a resonance unit including a differential negative resistance element, a first conductor, a second conductor, and a dielectric body, a bias circuit configured to supply a bias voltage to the differential negative resistance element, and a line configured to connect the resonance unit and the bias circuit to each other. The differential negative resistance element and the dielectric body are disposed between the first and second conductors. The line is a low impedance line in a frequency fLC of resonance caused by inductance of the line and capacitance of the resonance unit using an absolute value of a differential negative resistance of the differential negative resistance element as a reference.

    摘要: In a SAW oscillator, each of a first SAW element and a second SAW element includes interdigital electrodes and a reflector formed on a piezoelectric material. A first oscillating circuit part forms an oscillating loop including the first SAW element. A second oscillating circuit part forms an oscillating loop including the second SAW element. The first and second oscillating circuit parts have an identical admittance property. The first and second SAW elements are configured that an electrode pitch is identical and an admittance property indicating a relation between a frequency and an admittance value is different therebetween. Further, a first intersection point between the admittance property of the first SAW element and the admittance property of the first oscillating circuit part and a second intersection point between the admittance property of the second SAW element and the admittance property of the second oscillating circuit part are at different frequencies.

    摘要: A hyperfrequency generator comprising a source element (5) of negative resistance adjacent to a cylindrical resonant cavity (2) closed at opposite ends by two transversal closure plates (4, 7) for the purpose of tuning over a frequency band. The source element (5) is installed directly in the resonant cavity (2) such that there is a direct coupling between the source element (5) and the resonant cavity (2). One of the closure plates (7) is movable toward and away from the other for rough tuning.

    摘要: By using an EIP source lock counter, a frequency of a Gunn oscillator is stabilized. This increases the frequency stability of a circuit. An oscillation output of the Gunn Oscillator is supplied to the EIP source lock counter, and a phase lock signal indicative of a phase shift of the oscillation frequency from the EIP source lock counter relative to a preset reference frequency is supplied to a driver circuit. The driver circuit includes level shift circuit which level-shifts the phase lock signal thereof. A phase compensation circuit in the driver circuit boosts a gain as well as advances a phase at a high frequency region. The current amplifier circuit amplifies a current amplitude of the output of the level shift circuit, and the amplified output therefrom controls an oscillation frequency of the Gunn oscillator using negative feedback.

    摘要: An injection-locked waveguide oscillator comprises a first diode (3) having a free-running fundamental frequency above the local cut-off frequency of the waveguide (1) and a second diode (4) having a fundamental frequency below and a higher harmonic above the local cut-off frequency. The first diode (3) may be an IMPATT diode and the second diode (4) a Gunn diode. The free-running fundamental frequency of the first diode (3) is close to the higher harmonic of the second diode (4) so that the second diode (4) injection-locks the first (3). Locking in the reverse sense is inhibited by the inherent loss in conversion from the higher harmonic to the fundamental in the second diode (4), thus avoiding the need for a circulator or isolator. The two diodes (3, 4) preferably are mounted in a common waveguide (1) for a simple compact structure.
