Ceramic Filters

Ceramic filters, also known as ceramic resonators, are an important type of RF filter used for the control or manipulation of radio frequency signals. A ceramic filter consists of two components: a ceramic resonator and an associated circuit. The ceramic resonator is typically an ower frequency unit, usually below 500KHz, while the associated circuit is a high-frequency unit, usually above 500KHz up to several GHz. Ceramic filters are commonly used in radio receivers and transmitters, amplifiers, interfaces and audio systems.

CER0395A is one of the more popular models of ceramic filters. It is specially designed for high stability communication systems, such as GSM and CDMA. The device has a small footprint and low weight, making it suitable for portable applications. It is also highly immune to radiation, which makes it ideal for space applications. The device is frequency agile and can be adjusted between frequencies ranging from less than 15 MHz up to 600 MHz.

Working Principle

Ceramic filters work by filtering out unwanted frequencies in the radio spectrum. The filter is made of a pair of ceramic membranes, or resonators, that vibrate at a specific frequency. Inside the ceramic resonator is an associated circuit that is used to adjust the resonance frequency of the membranes. This allows the filter to work over a certain range of frequencies, with the exact range and characteristics of the filter determined by the electrical components used in the associated circuit.

When the filter is in operation, input signals that are at an unwanted frequency are absorbed and dissipated. The desired frequency signals, on the other hand, are passed through the filter and allowed to continue. Because of the precise nature of their operation, ceramic filters are widely used in applications that require high performance.

Applications

Ceramic filters are widely used in a range of applications, including:

• Radio receivers
• Television receivers and transmitters
• Mobile phones
• Radar and navigation systems
• Satellite communication systems
• Electronic warfare systems
• Wireless communications

CER0395A is specifically designed for high stability communication systems, such as GSM and CDMA. It is also suitable for frequencies up to 600 MHz, making it ideal for space communications.
