Ceramic filters have been used in the fields of communication, navigation, medical treatment, industrial control, and military communication for decades. CER0393B is a type of surface-mount ceramic filter which is widely used in radio communication because of its high selectivity and low insertion loss.

Applications

In the field of radio communication, CER0393B ceramic filters are mostly used in radio base stations, such as in the multi-pieces of main equipment with digital line in long-distance communication between the different machines used in subway, highway, harbor and other places, where is the need for efficient filtering of communication signals and high reliability. CER0393B ceramic filters are also widely used in radio communication of military, short-distance and satellite communication systems, especially those demanding ultra-high frequency filters. Additionally, CER0393B ceramic filters are widely used in medical equipment, industrial control equipment, navigation systems, digital transceivers, and other related digital electronic equipment.

Working Principle

Ceramic filters are based on quartz and piezoelectric materials, which can be used to convert electrical signals to mechanical vibrations. CER0393B filter contains a quartz crystal, which vibrates at its resonant frequency with the energy supplied from an external source. The vibration wave is propagated and concentrated on the surface of the ceramic material. This wave transmits through the internal grain boundaries of the ceramic material and is intercepted and reflected along its own phase. Consequently, a selective frequency transmission region appears among the passbands of the filters.

The passband width of the CER0393B filter is directly related to the size of the filter. The larger the filter, the wider the passband, and the better the filtering effect for signals of different frequencies. CER0393B filters can be used for both narrowband and wideband applications, and it is possible to design special filters for various special applications.

Advantages

CER0393B ceramic filters offer excellent performance in terms of frequency selectivity and attenuation. Their low insertion loss and excellent temperature stability can guarantee reliable operation and low cost maintenance. Also, the robust construction of CER0393B ceramic filter can withstand high relative humidity and wide temperature range which allows it to be used in harsh environment.
