Ceramic Filters

Ceramic filters have been used in electronic frequency selection for many decades. Their properties enable them to be used in many applications, including hum and noise cancellation, signal amplification, and signal mixing in both military and commercial applications. The CER0839B is a specific type of ceramic filter designed for use in those applications. It is a surface mount filter which offers excellent performance with low insertion loss and high out-of-band rejection.

CER0839B application fields

CER0839B is a DC blocking type of low insertion loss, low pull-in, and push-pull design, suitable for various applications like base station, mobile communication, wireless communication equipment, signal amplifying and other devices. It can be widely used in low-noise RF amplifier, VCO, transmitter, receiver, signal multiplexer, oscillator, and other applications where a signal needs filtering.This type of filter is offered in several variations including types with 80, 120 and 150MHz bandwidths, among others. Some of the benefits include low power consumption, high voltage capability, low leak current, and low out-of-band rejection.

CER0839B\'s Working Principle

CER0839B ceramic filters are constructed of several components such as a ferrite core, capacitor plates, and coils. The ferrite core is made up of a metal oxide material like iron, nickel, manganese, cobalt, aluminum, or other materials. This material has properties that make it excellent for blocking out unwanted frequencies while allowing those frequencies in the desired range to pass through. The capacitor plates are designed to store electrical energy while the coils give the filter its selectivity, allowing only the wanted frequencies to pass through.In operation, a signal that has components both inside and outside of the frequency range desired is applied to the filter. The energy of the unwanted frequencies is blocked by the ferrite core, while the desired frequencies pass through. The capacitor plates store the energy of the frequencies which are blocked. The coils act as an inductor, separating the frequencies and letting the desired frequencies pass through. The CER0839B is a surface mount ceramic filter, meaning that it is mounted directly onto the circuit board and can be installed in confined spaces. This filter offers excellent performance, robustness, and reliability compared to other filter types.Ceramic filters have become increasingly popular in recent years, as they offer excellent performance in a variety of applications. The CER0839B is one such filter, offering broad band rejection and low insertion loss in a packaged form. It is ideal for use in corporate, consumer, and military applications due to its low power consumption, robustness, and reliability.
