What do you mean by 'smaller', Mike? If it's physical size, there were a helluva lot of 1nF tubular ceramics doing a fantastic job in the 30MHz - 40MHz range decoupling TV IF strips. If its value you mean, I'm sure that very low values of ceramic capacitor with carefully specified temperature coefficients have been used to build frequency stable RF oscillators.
