An oscillator ( 100, 200 ) and a method of adjusting the frequency of oscillation of the oscillator ( 100, 200 ) are disclosed for generating a signal with an adjustable frequency in a frequency range from 1 GHZ to 200 GHz. The oscillator ( 100, 200 ) includes a loop circuit. The loop circuit has an amplifier ( 101 ), a delay element or filter ( 103 ), a phase shifter ( 102 ), a device for adjusting the phase shifter ( 102 ), and a coupler ( 104 ) to provide an output signal. The adjusting device is coupled to the phase shifter ( 102 ).
