What is a crystal oven?
Crystal oven is a sealed environment located around a quartz crystal in high -precision devices. These furnaces maintain a constant temperature and pressure and insulate the internal crystal from changes in the environment. Generally, a crystal oven is used only on extremely high -accurate devices such as military radio systems and cellular towers. On lower exact devices, the advantage is far bent down the costs and possible most devices.
When a quartz crystal is used as a resonator in the device, it is the main part of the sending and receiving signals. The resonance frequency of quartz is used to tune the transmitter and maintain stable signals sent. The frequency of quartz is determined by several factors, including the size of the crystal. As quartz is heated and cooled, it can expand and download. This results in a change in small size that changes the frequency of crystal.
devices that cannot afford to have a frequency fluctuation use a crystal oven to keep crystalline stable. By maintaining a hundredCrystal's brandy situation, regardless of the real conditions, will never change its frequency. The most common form of crystal furnace is used inside the crystal oscillator.
The crystal oscillator is a common component found in precise measuring devices, broadcasts and reception. These devices can be very small and are often integrated directly into the perimeter of the device. When a crystal oven is used in these devices, it is usually an insulating device that is not driven. It relies on its mechanical construction to maintain crystalline stable.
other devices have larger furnaces that work on a completely different scale. These devices are built as sealed canisters containing their own stable environment. These furnaces often require external performance and specially designed crystals. While this type of crystal oven can be much larger than the version of the oscillator, the version E is still dFurthermore, small to connect directly to the circuit system.
In most cases, crystal furnaces are not unnecessary. On common electronic devices, the accuracy degree given is much more than the user requires. This, along with the added costs of their construction to the equipment, causes many manufacturers to skip them into their designs.
On the other hand, users require a very high level of accuracy or stability. This usually occurs at the consumer level in high -end watches, diagnostic tools and sound devices. At a commercial level, they use local transmission hubs such as cellular towers or radio transmission stations, these furnaces to maintain their frequencies in the correct bandwidth. Finally, military systems use these furnaces to maintain narrow transmission belts to prevent unwanted bleeding to neighboring frequencies.
