Figure 16 shows a schematic diagram of an 11 GHz oscillator stabilized by a dielectric resonator.

To determine the optimum temperature coefficient, the simplest solution is to make a first assembly with a material of zero or given coefficient τ_f0, optimizing all parameters other than temperature stability (center frequency, spectral purity, insertion losses, ripple...). The coefficient τ_f1 of this assembly is then measured, and a second assembly is then made with a material of coefficient –τ_f1 + τ_f0 reproducing as closely as possible the coupling conditions...
