    摘要: A push-push oscillator including a resonator having a transmission line and a capacitance connected to the transmission line in parallel; an oscillating circuit responsive to the resonator for oscillating and for producing first and second outputs having an antiphase relation therebetween; an in-phase combining circuit for summing the first and second outputs of said oscillating circuit to produce a summed signal; and an antiphase combining circuit responsive to two components from the resonator having an antiphase relation for producing a differential signal in accordance with a difference between the two components. Alternatively, the in-phase combining circuit is connected to the resonator and the antiphase combining circuit is connected to the oscillating circuit. The antiphase combining circuit outputs a fundamental wave component of the resonator. The in-phase combining circuit outputs a second harmonic wave component. When this push-push oscillator is used in a PLL circuit to form a frequency synthesizer, a high frequency output is obtained with a low power consumption.

    摘要: A miniaturized circuit for high frequency operation is formed of four successively superimposed dielectric layers, with a microstrip resonance element being sandwiched between two inner dielectric layers which themselves are sandwiched between opposing ground plane layers, and the other dielectric layers being respectively formed upon these ground plane layers. Circuit connection patterns are formed on the outer faces of the latter dielectric layers, and circuit components mounted thereon to form two circuit sections. The microstrip resonance element can be utilized as an inductive reactance element of an oscillator circuit, or as a filter circuit resonator element, and is effectively shielded by the ground plane layers which also effectively mutually isolate the two circuit sections.

    摘要: An oscillator includes an oscillator circuit which includes an oscillator transistor and a resonant circuit. The oscillator circuit can change an oscillation frequency. An amplifier circuit receives an oscillation signal output from the oscillator circuit and amplifies the oscillation signal. The resonant circuit is connected at high frequencies between the base and the collector of the oscillator transistor. The oscillation signal is output from the resonant circuit.
