  • Frequency adjustable oscillator and methods of operation
    Patent number: 6882234
    Abstract: 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).
