Abstract
There is disclosed a first stub short bonded across conductive runners of a tuning stub at a distance preferably greater than a distance resulting in the desired frequency of operation of a voltage controlled oscillator tuned by the tuning stub. Thereafter, the voltage controlled oscillator is powered and tested to determine the frequency of operation of the voltage controlled oscillator. The position of a second stub short is determined based on the frequency of oscillation of the oscillator due to the presence of the first stub short, the geometry of the tuning stub and the desired frequency of operation of the voltage controlled oscillator. A second stub short is precisely positioned along the stub using automated equipment, relative to the position of the first stub short, to result in the desired frequency of operation of the voltage controlled oscillator. Depending on the relative positions of the first and second stub shorts relative to the voltage controlled oscillator, the first stub short may be removed. The voltage controlled oscillator may again be powered and tested to confirm the desired frequency of operation of the voltage controlled oscillator.
