    Abstract: Systems for controlling the frequency of the output signal of a controllable oscillator (202) in a frequency synthesizer (200) are provided. One such system comprises a controllable oscillator (202) and a frequency control circuit (208). The controllable oscillator (202) is configured to generate an output signal that has a predefined frequency. The controllable oscillator (202) is also configured with a plurality of operational states that are controlled by the frequency control circuit (208). Each operational state of the controllable oscillator (202) defines a distinct frequency for the output signal of the controllable oscillator (202). The frequency control circuit (208) receives the output signal of the controllable oscillator (202) and determines the distinct frequency for the output signal that best approximates the predefined frequency. The frequency control circuit (208) may also provide a control signal to the controllable oscillator (202) that is configured to change the controllable oscillator (202) to the operational state corresponding to the distinct frequency that best approximates the predefined frequency.

    Abstract: A resonator (50) is connected in circuit with a negative resistance element (Q3,Q4) for producing oscillation at a resonant frequency of the resonator (50). A digital phase shifter (58) is incorporated into the resonant frequency in accordance with an applied digital signal. The resonator (50) can be connected in series with the negative resistance element (Q3), in which case the phase shifter (58) is connected as either a short-circuit or an open-circuit transmission line. Alternatively, the resonator (50) can be connected in parallel with the negative resistance element (Q4) in a feedback loop. An analog phase shifter (84) can also be provided in the resonator (50') for continuously variably setting the resonant frequency over the tuning increments of the digital phase shifter (58).

    Abstract: A phase modulator includes a digital frequency word generator, an adder and a register arranged to generate recurrent digital sawtooth signals at a carrier rate. A second digital adder is coupled to receive the sawtooth signals and also receives digital information signals. The adder produces recurrent digital sawtooth signals phase-modulated by the information signal. A pair of adders receive the digital sawtooth signals and mutually sign-reversed digital information signals to produce a pair of oppositely phase-modulated constant-amplitude signals in a pair of channels. A sine memory is addressed by the phase-modulated digital sawtooth signals to produce phase-modulated sinusoidal-representative digital signals. The digital signals are then converted to analog signals. Since the two channels contain signals which are phase-modulated but not amplitude-modulated, the signals may be amplified by nonlinear amplifiers. An adder is coupled to the outputs of the two channels to sum together the two phase-modulated signals to produce an amplitude-modulated signal. Combinations of amplitude and phase modulation may be generated by a combined structure.
