一、Characteristics

     S-band bandpass filter (cavity bandpass 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 wide frequency coverage range is 2GHz-4GHz, the high-end parasitic passband is far, the consistency is good, the size is small, the Q value is high, 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, and the design can be designed according to the user's requirements and the installation method.

    Limit parameter: the maximum input power is 50W; The operating temperature range is -55℃~+85℃; The storage temperature range is -65℃~+125℃. When the S-band bandpass filter is used, pay attention to the good grounding of the shell, otherwise it will affect the out-of-band suppression and flatness index.

三、Application & attention

      Because the S-band bandpass filter (cavity bandpass filter) has a good frequency selection filtering effect in circuits and electronic high frequency systems, and can suppress unnecessary signals and noise outside the frequency band, it is widely used in T/R components, radar detection, electronic countermeasures, aerospace, radar, wireless communication, radio and television and various electronic test equipment. When in use, the input/output outlet can be used interchangeably, but pay attention to good grounding of the housing, otherwise it will affect out-of-band suppression and flatness indicators. Products should be stored in the ambient temperature of -10℃~40℃, relative humidity is not more than 80%, the surrounding environment is not acidic, alkaline and other harmful gases in the warehouse. Do not soak when cleaning, it is recommended to wipe with alcohol.

     This series of products is highly customized products, flexible design, can be determined according to user requirements, can provide a variety of international standard interface mode, a variety of fully sealed shell packaging form and a variety of response functions optional. It can also be customized according to the user's requirements of external packaging, out-of-band suppression and other indicators. The company custom S-band band-pass filter, cavity band-pass filter, band-stop filter, high power cavity filter.
