    FILTERS

    RF and Microwave Filters are historically the main products manufactured at Deti. Our filters are especially thought to perform into harsh environmental conditions so they are suitable for military application in ship or airbone systems. There are 4 types of filters: lowpass, highpass, bandpass and bandstop filter. For each category, different technologies can be used as needed for bandwidth and/or power handling. They are used in various areas for many applications, such as Electronic Warfare (EW), RADAR, communications, wireless market and reception / transmission channels, to pass signals in a desired frequency band, and reject undesired signal outside this band.
    For high power filtering, we can provide mechanical structure with low insertion loss. For high selectivity we can provide high order filters, and optionally with additional ‘zero’ rejectors to enhance attenuation in rejection band.

    Depending of bandwidth, we can choose among several technologies : cavity, slabline, printed circuits or lumped elements for the most commons.

    Each technology has its qualities and defaults, compromises often have to be made, for example, upper band rejection of a bandpass filter will be limited due to harmonic effect, just like passband of highpass filter will not tend to infinite because of spurious inherent of elements of the structure.

    A mechanical filter will have good insertion loss thanks to a high quality factor, but price will also be higher than a printed circuit filter. We have to take into consideration performances to avoid overqualified products, if a standard part can make the deal at a lower cost.
