Crystals: 9C12020001 Application Field and Working Principle

Crystals are a type of semiconductor device with a wide range of applications. The 9C12020001 one is a type of surface acoustic wave (SAW) crystal, specifically designed for low-frequency applications as wireless standards for short-range communication technologies. This article will discuss its working principle and application field.

A 9C12020001 is a type of quartz crystal SAW device. The SAW device consists of a piezoelectric substrate (typically quartz) and two interdigitated transducers (IDTs). By applying an electric field to the IDTs, acoustic waves are generated in the substrate, which act to modulate a desired frequency in the device.

The 9C12020001 is designed to achieve low-frequency ranges as it is a special type of quartz crystal SAW device. The low-frequency range is possible because of its low-cutoff characteristic. This is achieved through the design of the IDT period and number. The number of finger pairs in the IDT period and the finger width are maintained to obtain a low-frequency cutoff.

The 9C12020001 is commonly used in short-range communication technologies, such as Zigbee, Bluetooth, and Wifi. These technologies require low-frequency characteristics to reduce transmission power levels and enable better reception of signals within a short-range. The low-frequency characteristics also enable increased data rate, as higher data rates are easier to achieve at lower frequencies.

The 9C12020001 can also be used in other low-frequency applications, such as the synchronization of pulse signals in broadcast TV systems, optical communication systems, and radar systems. It is also used in wireless sensor networks and wireless medical systems, such as those used for medical monitoring of vital signs or movement tracking.

In summary, the 9C12020001 is a type of quartz crystal SAW device designed for low-frequency applications. It is commonly used in short-range communication technologies, such as Wifi and Bluetooth, as it enables increased data rate and lower transmission power levels. Additionally, it can be used in other low-frequency applications, such as in broadcast TV systems, optical communication systems, radar systems, and wireless sensor networks.
