416F37423CST Application Field and Working Principle

Crystals, also known as quartz crystal momentary switch, are widely used in electrical circuits and are currently leading the trend of "electronic intelligence" such as aviation and defense, home appliances, communications and computers. Its application early was in the military field, electronic watches and communication equipment, with the development of electronic technology, crystals are also widely used in various fields.

416F37423CST is a three-terminal SMD crystal switch, including a fitting tuning capacitor, designed for wireless communications: it can be used for GPS, WLAN and Bluetooth modules. The switch is miniatured, small capacity current, and low power consumption, which saves PCB area, the cost of electronic circuit, greatly improves the efficiency.

Working Principle of 416F37423CST

The 416F37423CST is based on MEMS (Micro-electro-mechanical System) technology, which integrates MEMS switches and MMICs to provide attractive features such as low insertion loss, low control power, miniaturized size and wide frequency range. The MEMS switch includes a switching membrane on top of a SiO2 post substrate, a SiO2 dielectric cancellation block and a metal contact. When the input voltage of the chip reaches the designated voltage, a MEMS switch turns on, and after the input voltage declines below the designated voltage, the MEMS switch automatically turns off. Therefore the chip can undertake reliable on/off control.

The main reason that makes 416F37423CST switch so popular today is that it can realize the high frequency switch, its frequency of up to 5GHz and beyond on C band. The switch is adopted for wireless wideband applications, such as GPS, WLAN, DTV and satellite communications, it has low insertion loss, low power consumption and power compression.
