In many applications, for example a direct digital synthesis, it is necessary to use the high quality and on higher overtone working crystal oscillator. One of the best circuits for this purpose is Butler oscillator as emitter follower. By this circuit is possible to design a high frequency oscillator working up to hundred megahertz. In this paper the design of the Butler oscillator at 2^26 Hz by use of a feedback loop analysis in resonance frequency vicinity of the crystal is showed. Influence of the circuit elements values is calculated in Matlab environment. This is important for low phase noise (high short-term stability) oscillator design and stability of the output signal amplitude. The design is oriented on the maximum short-term stability. The next step is determination and optimalization of the power dissipation in the crystal unit. For decreasing of this power dissipation we use limiting diodes.
