    Abstract: A frequency adjustable surface acoustic wave oscillator uses circuitry in which the phase relationship between the corresponding input and output signals and the voltage applied to or received by transducer fingers is controlled in such a manner that the frequency of the surface acoustic wave oscillator is arbitrarily controlled over a wide range by digital means. This provides an oscillator that exhibits a wide tunable frequency range while providing low phase noise.

    Abstract: A circuit using a voltage-controlled oscillator with a hyperabrupt junction diode in the series resonant circuit is operated as a variable frequency modulation circuit. An amplifier with an inductor in the base circuit of a common base configuration is used to present an impedance with a frequencydependent real part to the series resonant circuit of the oscillator. The nonlinearities in the characteristic of the hyperabrupt junction diode are compensated by the frequencydependent real input impedance to achieve linear operation.
