445A33A16M00000 Datasheet/PDFThe type of crystal referred to as the 445A33A16M00000 is typically used in a range of microelectronics industries. Commonly referred to as a varactor or variable capacitor, this type of crystal is used as part of a process that uses an electric field to change the capacitance of a circuit. As a result, the frequency in which the device operates can be adjusted. With this type of crystal, the capacitance is manipulated by introducing a reverse bias to the junction of the crystal, and is capable of changing capacitance within its functional range.
This crystal was designed to offer increased consistency in performance and wide tolerances, ensuring that the capacitance is accurately maintained across its entire operation. The range of frequency achieved is also wide, and is usually able to stay within 0.5% of its frequency across its entire range. In addition, the device is designed to limit the amount of power that is used as part of its operation, ensuring power savings wherever possible.
In terms of application, the these crystals are commonly found within different kinds of radio frequency devices, such as mobile phones, radios and advanced transceiver systems. They are also used in short range communication systems such as Bluetooth, and are used for internal circuitry within the design of other electrical applications. By altering the capacitance within a circuit, the overall frequency can be tuned and adjusted to a specific rate in accordance to the application.
The operation of this type of crystal is relatively straightforward. A reverse bias is applied to the junction which effectively lowers the capacitance, shifting the overall frequency in the opposite direction. This type of crystal is commonly used in a voltage controlled oscillator, whereby a specific voltage is used to change the oscillation frequency.
In conclusion, the 445A33A16M00000 crystal is a reliable means of modifying a frequency range. By applying a reverse bias, changes can be made to the capacitance with the result of the overall frequency shifting in the opposite direction. Capable of providing accurate measurements and highly tolerant performance, this type of crystal is commonly used within a range of radio and wireless communication systems.
