Ceramic Filters offer very high selectivity and high power handling capabilities for applications such as mobile and wireless communications, base station transmitters and receivers, medical devices and instrumentation. In these applications, they provide radio frequency (RF) signal conditioning by rejecting undesired signals while allowing in-band signals to pass. CER0139B is a high performance packaged ceramic filter with superior RF characteristics, wide operating temperature range, and low power consumption.

The CER0139B is designed to emphasize a wide passband insertion loss while still providing good rejection and steep roll-off characteristics. It provides high selectivity and low insertion loss from 10MHz to 1770MHz with S.D.R. up to 30 dB. The CER0139B is available in a RoHS compliant lead-free, low-thermal-conductivity, sealed package.

The CER0139B filter has excellent environment-resistant properties for long-term stability and reliable performance. It offers exceptional performance within the rigorous requirement for wireless communication transceivers. When integrated into the design of these products, CER0139B ceramic filters provide outstanding insertion loss, close stop-band characteristics and high attenuation. In addition, the package offers superior performance in the most demanding applications.

The CER0139B ceramic filter is based on a standard three-pole topology, with the input and output capacitors being ceramic disc capacitors. The ceramic filter is constructed using multiple interconnected capacitors in the filter section, which are formed by etching a ceramic dielectric material into the desired frequency and impedance characteristics. All the components used in the device are then integrated into a hermetic package in order to ensure reliable long-term performance. The filter section is then doped with a highly conductive metal, typically gold, which is used to form the resonators to achieve the desired frequency response. The casing is then filled with a high-pressure dielectric gas, which is used to create a waveguide for the signal.

The CER0139B ceramic filter is ideal for use in a variety of applications, including microwave and wireless communications, instrumentation, test and measurement, medical electronics, and automotive systems. It is designed to provide superior RF signal conditioning and filtering performance in the most demanding applications. With its excellent performance, wide operating temperature range, and low power consumption, the CER0139B ceramic filter can help improve the performance and reliability of any communication system.
