Located in the field of ceramic filters, CER0325C is a high-performance ceramic filter. It boasts excellent temperature stability, high frequency accuracy, low insertion loss, and high out-of-band rejection.

CER0325C is widely used in the fields of digital TV, radio, and mobile phones, as well as other receivers requiring high linearity. It has served as an essential component in communication systems and high-precision analog circuits.

CER0325C consists of a dielectric substrate made of a ceramic barium titanate material. This supports two small copper pieces that serve as the antenna and terminal. This filter also provides dual band filtering to ensure high signal integrity, shielding against unwanted signals, and a low insertion loss of up to 0.14dB. It operates in temperatures ranging from -25°C to +85°C.

The working principle of the CER0325C is based on impedance matching. This filter uses a radio-frequency (RF) signal, which passes through two pairs of high and low impedance resonators. The resonators help to match the impedance of the signal through the filter, while also optimizing the signal’s bandwidth. In order to achieve this, the resonators must be tuned to the same frequency as the signal, which allows the signals to travel through the filter with minimal loss.

CER0325C also includes an amplifier, which effectively boosts the signal-to-noise ratio so that the signal can be read without experiencing any distortion or signal loss. It also uses a voltage taps input, which allows the input level of the signal to be adjusted. This makes it possible to obtain a desired signal-to-noise ratio depending on the application.

CER0325C has a wide range of applications across various industries. It is widely used for TV, radio, and mobile communication systems, as well as consumer electronics and defense systems. It is used in high-precision analog circuits for filter signal transmission, in high-frequency radio receivers for eliminating noise, and in high-speed communication networks.

The working principle and application field of the CER0325C ceramic filter make it an ideal component for high-precision communication systems. Its excellent temperature stability and high frequency accuracy ensure reliable performance and signal integrity. Furthermore, its low insertion loss and high out-of-band rejection provide protection against interference and other external signals. This makes it an invaluable component for a variety of applications across numerous industries.
