1. A digitally-controlled SAW stabilized FSK oscillator circuit comprising:

  • an oscillator;

    a single-port SAW resonator having a predetermined circuit resonant frequency and being coupled to the oscillator for establishing a first oscillator output frequency, FSAW ; and

    a transistor having an ON and an OFF state, only said transistor being coupled in series with the single-port SAW resonator for establishing the first frequency, FSAW, when the transistor is in the ON state and causing said oscillator to shift its output frequency from the first frequency, FSAW, to a second frequency, F2, when said transistor is in its OFF state.
