Surface acoustic wave (SAW) filters are a type of electromechanical filter used to reduce interference while improving signal strength. The ECS-D479.5B filter is an example of a SAW filter used in a variety of applications. It is designed to reject interference while allowing signals to pass through. This article discusses the applications of the ECS-D479.5B filter and its working principle.

ECS-D479.5B Application Field

The ECS-D479.5B filter is primarily used in the military, communication and industrial sectors. In the military sector, it is used to control radio interference when a sensitive signal is present. In the communication sector, it can be used in cellular phones, Wi-Fi routers, radio transmitters, and other digital communication systems. It is also used in industrial environments to increase signal reliability and reduce noise. It can be used in a variety of industrial applications including assembly lines, manufacturing plants, and data centers.

Working Principle

The ECS-D479.5B filter is made up of two quartz crystals which are joined together and held in place by a constant spring. The two crystals generate an acoustic wave when vibration is applied to them. The frequency of the vibration is determined by the thickness and mass of the crystals, as well as the tension of the spring. The vibration is then transformed into electrical signals. This process allows the ECS-D479.5B to selectively filter out certain frequencies, allowing signals to pass while rejecting interference.

The ECS-D479.5B can be tuned to different frequencies depending on the application. The filter has a frequency range between 740MHz and 1250MHz, with a response time of less than 10nS. It also has a temperature range of -60C to +125C and a power rating of 400mW. This makes it suitable for use in a range of applications.

Conclusion

The ECS-D479.5B is a SAW filter designed to reduce interference while improving signal strength. It is used mainly in the military, communication, and industrial sectors. Its working principle is based on the use of two quartz crystals which generate an acoustic wave when vibration is applied to them. This wave is then transformed into electrical signals, allowing the ECS-D479.5B to selectively filter out certain frequencies. The filter is tuned to different frequencies depending on the application, and it has a frequency range of 740MHz to 1250MHz, a response time of 10nS, and a temperature range of -60C to +125C. This makes it a suitable choice for a variety of applications.
