Claims19
A temperature stabilized frequency control device comprising frequency determining components including a resonator and frequency determining components other than the resonator, a heat distributor, and a substrate having a thermally conductive layer therein and carrying at least some of the frequency determining components other than the resonator, wherein
- the heat distributor is arranged to define, in conjunction with the substrate, a space in which at least some of the frequency determining components other than the resonator are located,
- the heat distributor is thermally connected to the thermally conductive layer in the substrate,
- the heat distributor is arranged to spread heat throughout the resonator and throughout the said space, and
- wherein the resonator is installed onto the surface of, and in close thermal connection with, the heat distributor.
A temperature stabilized frequency control device comprising frequency determining components including a resonator and frequency determining components other than the resonator, a heat distributor, and a printed circuit board having an internal metal layer and carrying at least some of the frequency determining components other than the resonator, wherein
- the heat distributor is arranged to define, in conjunction with the printed circuit board, a space in which at least some of the frequency determining components other than the resonator are located,
- the heat distributor is thermally connected to the internal metal layer,
- the heat distributor is arranged to spread heat throughout the resonator and throughout the said space, and
- wherein the resonator is installed onto the surface of, and in close thermal connection with, the heat distributor.
