  • Abstract
    The principle of phase control by harmonic locking is verified experimentally, using a 1 GHz transistor oscillator locked to a 4 GHz source. Phase steps of ±90° can be obtained by the application of positive- or negative-voltage pulses to the locked transistor. Phase switching can be achieved in 40 ns.
