The design procedure and the electrical performances obtained with very small ovenized oscillators are presented. The sizes were reduced to 40 by 30 by 19, 40 by 30 by 16, and 36 by 26 by 19 cu mm. The oscillator designs offer 'intrinsic' high performances regarding either aging, frequency stability, or phase noise in the way that these performances can be compared to the one achieved from actual standard oscillators designed in a larger package. One of the keys in getting ovenized oscillators in small package is the resonator definition. The use of SC cut allow good performances in ageing, thermal stability and phase noise, in smaller size than an equivalent AT cut. Miniaturized and stable oscillator specifications can be met by using state of the art of oscillators design and manufacture concepts. The experimental results show that tight requirements are obtained with very good oscillator yields.
