Crystal-controlled transistor reflection oscillator easily tunable and stable, consumes little power, and costs less than other types of oscillators operating at same frequencies. Made possible by design concept that includes operation of transistor well beyond 3-dB frequency of current-versus-frequency curve. Concept takes advantage of newly available crystals resonating at frequencies up to about 1 GHz. Useful in determining approximate frequency of oscillation and major elements determining frequency.
