    Abstract: A PHS relay station demodulates a digital signal from a received radio-frequency signal by use of a reproduction clock produced from the digital signal. The relay station has an oscillator which generates a clock and a variable-ratio frequency divider for the clock outputted from the oscillator. A bit clock is produced from the output of the divider. A signal processor processes the digital signal by use of the bit clock. A detector detects a specific code in the digital signal in synchronism with the bit clock. The length of time that passes after the specific code detection signal is generated until the reproduction clock changes its level is detected as the phase deviation between the reproduction clock and the bit clock. The phase deviation is eliminated by temporarily changing the frequency division ratio of the divider in accordance with the amount of the deviation.

    Abstract: A first oscillator includes: a ring resonator; an oscillation circuit having a negative resistance active circuit coupled to a first point on the ring resonator for oscillating at an oscillation frequency and resonating the resonator; an output terminal, coupled to a second point on the ring resonator where a voltage is substantially zero with respect to the predetermined frequency when the ring resonator resonates, for outputting a resonant frequency signal, wherein even order harmonic components are outputted with the fundamental component suppressed. A second oscillator includes a ring resonator having points A to D equidistantly dividing the ring resonator, first and second oscillation circuits coupled to the points A and B respectively, first and second grounding capacitors having capacitance equivalent to those of the first and second oscillation circuits. Thus, two independent oscillators which do not affect each other are provided with a single resonator. In the first and second oscillators, grounding capacitors, a resonant capacitor may be provided to miniaturize the oscillator. Variable capacitances may be provided to prevent the point from moving with a change in the controlled oscillation frequency. Frequency synthesizers and communication apparatus including the first or second oscillator are also disclosed.

    Abstract: An oscillator having two oscillation circuits (01, 02) with widely different frequencies with a common passive switched output circuit (OP1). Each oscillator circuit (01, 02) includes a transmission line inductive impedance (L3, L13) between the oscillator output and ground. The inductive impedances (L3, L13) are selected to be open at the operating frequency of the associated oscillator circuit and a short or a low impedance at the frequency of the other oscillator circuit. Each inductive impedance (L3, L13) forms a portion of an impedance matching pad for the other oscillator circuit.

    Abstract: The invention relates to a microwave oscillator comprising a short-circuited wave-guide (1) and a diode (2) arranged therein which receives the supply voltage thereof via a coupling pin (6) conveyed through a wave-guide wall (8). Said oscillator has at least one compensating pin (11) which has an adjustable penetration depth and projects into the wave guide, and is intended to tune in the oscillator frequency. Tuning in of the oscillator frequency can be very accurate because the compensating pin (11) is aligned at an acute angle to the coupling pin (6).

    Abstract: Mittels einer Kapazitätsdiode abstimmbare Mirkowellenoszillatoren weisen für Schwingfreuqenzen von maximal 1 GHz als frequenzbestimmendes Glied häufig einen keramischen Koaxialresonator auf, bei dem an einer Stirnseite die Metallisierung entfernt und dort die Kapazitätsdiode angeschlossen ist. Bei Frequenzen oberhalb von 1 GHz, also insbesondere bei Frequenzen um 2,5 GHz, kommt es zu störenden Resonanzen und damit zu ungewollten Schwingfrequenzen durch den Serienresonanzeffekt der Kapazität der Abstimmdiode mit ihrer Anschlußinduktivität und durch die mechanischen Abmessungen des keramischen Koaxialresonators. Erfindungsgemäß wird deshalb der Emitteranschluß des Oszillatortransistors über einen Koppeldraht mit dem Innenraum des keramischen Koaxialresonators verbunden und die Kapazitätsdiode am anderen Ende des Koppeldrahtes angeschlossen.
