EFC-H836MTCD1 Filters

SAW filters are widely used in the telecommunication field. The device comprises of a basic building block, namely an acoustic surface wave (SAW) filter, which is used to filter out unwanted signals from a communication system. The EFC-H836MTCD1 is one such device that is designed to meet rigorous demands for high-performance communication systems. This article discusses the application field and working principle of the EFC-H836MTCD1.

Application Field

The EFC-H836MTCD1 device is designed to meet stringent requirements for high-performance communication systems. It features low insertion loss, high selectivity, fast settling time and good temperature stability. It is suitable for use in sectors such as mobile communication, satellite communication, navigation, and communication military systems as well as industrial, scientific and medical (ISM) systems.

Working Principle

The working principle behind the EFC-H836MTCD1 SAW filter is based on its acoustic resonance behaviour. A thin film of piezoelectric material is placed on a specially designed metal waveguide surface. This film is excited by an alternating electric field which produces a standing wave having nodes and antinodes. When a signal of a particular frequency is sent to the device, it produces a resonant frequency determined by the geometry of the device and the material used for the waveguide. This resonant frequency is then used to select the wanted signals while rejecting unwanted ones.

Conclusion

The EFC-H836MTCD1 is a SAW filter designed to meet the needs of demanding high-performance communication systems. It features low insertion loss, high selectivity, fast settling time and good temperature stability. This device is suitable for use in sectors such as mobile communication, satellite communication, navigation, and communication military systems as well as industrial, scientific and medical (ISM) systems. It works on the principle of acoustic resonance behaviour, wherein a resonant frequency is used to select the wanted signals while rejecting unwanted ones.
