ABSTRACT:
The broadband injection locked oscillator system comprises a first voltage controlled oscillator having a signal output for a first signal controlled to have a first frequency in a first relatively broad frequency range, and a second voltage controlled oscillator having a signal output for a second signal controlled to have a second frequency in a second relatively broad frequency band. The output of the second oscillator is coupled to a signal input of the first oscillator to injection lock the first oscillator to the second oscillator. The second frequency is harmonically related to the first frequency when the injection lock occurs.
