A symmetrical transistor oscillator with low second-harmonic distortion
W. M. Grim · Transactions of the American Institute of Electrical Engineers Part I Communication and Electronics · 1956
THE oscillator described in this paper was designed to supply the excitation or carrier signal for a second-harmonic type of magnetic modulator. A brief discussion of the modulator will show the necessity for the unusual characteristics of the oscillator; namely, low second-harmonic distortion combined with amplitude and frequency stability.
