一、Characteristics
Cavity filter/pin filter is cut by the whole metal, solid structure, high reliability, input/output 50Ω impedance matching, easy to cascade use, input/output interchangeable use; Stable and reliable performance in the full temperature range, meeting the requirements of military working environment (-55℃ ~ +85℃); The frequency range is 0.5~18GHz, the high-end parasitic passband is far, the consistency is good, the size is small, the Q value is moderate, the standing wave is small, the in-band amplitude frequency characteristic is flat, the insertion loss is small, the out-of-band suppression is high, the design is flexible. There are a variety of interfaces to choose from, which can be designed according to user requirements and installation methods.
Limit parameter: the maximum input power is 100W; The operating temperature range is -55℃~+85℃; The storage temperature range is -65℃~+125℃. When using cavity filter/pin filter, pay attention to good grounding of the shell, otherwise it will affect out-of-band suppression and flatness indicators.
