The CER0230C ceramic filter is a type of filter used to provide narrow band filtering capabilities. The filter is especially useful in a wide variety of applications such as radio transmitters and receivers, in military communication systems, in navigation systems, in point to point radio links, and in satellite communications.

The CER0230C is a surface mount device which consists of two ceramic parts and two electrodes. The inner ceramic part is the resonant cavity, while the outer ceramic part supports it. The two electrodes provide the necessary electrical connection between the resonant cavity and the outside circuitry.

The working principle of a ceramic filter is based on the fact that when an alternating voltage is applied across the two electrodes, an electrical resonance develops in the resonant cavity. This electrical resonance causes the resonant cavity to resonate at a specific frequency, known as the resonant frequency. All the other frequencies are attenuated or completely eliminated. Depending on the design of the filter, either a band-pass or a band-stop filter can be achieved.

The CER0230C offers excellent temperature stability, low insertion loss, and high out-of-band rejection. These features make the CER0230C well-suited for radio communication applications, which require a reliable and consistent performance over a wide temperature range. The filter is also suitable for use in GPS and navigation systems, and for point-to-point radio links. In addition, the filter can be used in military communication systems for applications such as UHF and VHF communication.

In summary, the CER0230C is a ceramic filter used to provide narrow band filtering capabilities that are suitable for a wide range of applications. The filter features excellent temperature stability, low insertion loss, and high out-of-band rejection, making it ideal for radio communication systems, GPS and navigation systems, and point-to-point radio links. Furthermore, the filter can be used in military communication systems.
