ABSTRACT:
A voltage controlled oscillator provides a trimming stub (3) for adjusting a free-running frequency in parallel to a microstrip line resonator (4). This arrangement makes it possible to easily perform fine adjustment of a free-running frequency used in the voltage controlled oscillator capable of supplying 2 GHz or higher oscillating frequency.
