Ceramic filters are a type of filter that utilizes a piezoelectric material as the active filter element. The CER0358B is a ceramic filter that combines the features of high-frequency & high off-frequency selectivity, low insertion loss, and high cutoff frequency with low temperature drift. The filter is designed for applications in frequency bands ranging from 5GHz to 40GHz and offers a low pass frequency range of up to 1000MHz with high stop-band rejection and pass-band ripple specs of ± 1dB typically over the full frequency range.

The CER0358B ceramic filter can be utilized in a variety of applications including microwave antennas, digital set-tops, satellite systems, consumer communication receivers, and wireless system base stations. It is also capable of being used in GPS and Point-to-Point communication systems, signal conditioners, audio filters, modulators, and filters for multiple sources.

The filter utilizes a small surface mounted component which takes only a few millimeters of board space, reducing system costs while offering high band selectivity. The filter also features low signal distortion, high input and output impedance, and good power handling capabilities. The filter also provides a wide pass-band frequency range with no phase distortion, which makes it ideal for radio modem applications.

The working principle of the CER0358B filter is based on the piezoelectric effect. In this module, a piezoelectric crystal is used as a filter element. When an electrical signal is applied, the crystal vibrates according to its physical properties. This vibration causes the filter to absorb certain frequencies, while allowing others to pass through. This allows the filter to produce gain across a specific frequency band while rejecting signals outside of this band.

The CER0358B filter is designed with a low-pass characteristic for applications up to 40 GHz. The filter offers a good level of suppression over the stop band, while maintaining a low pass-band insertion loss. This helps to reduce the cost of the system while maintaining a high-level of performance. The filter also offers wide-band selectivity, along with good linearity and power-handling capabilities.

In conclusion, the CER0358B ceramic filter offers a cost-effective solution for applications where wide band selectivity, low-pass characteristics, and high off-frequency selectivity is needed for radio communications. The filter also offers a low insertion loss, and good linearity and power handling capabilities. The filter utilizes a small surface mounted component which takes up only a few millimeters of board space, and is ideal for applications that require high band selectivity while keeping costs low.
