    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.

    There is 4 main type of filters :

    • Lowpass filters allows the signal to pass usually from DC to Fmax with a controlled VSWR and Insertion Losses. For higher frequencies than the defined rejection (or cutoff) frequency, the signal is attenuated by a value in dB. However please note that if an ideal Lowpass filter can reject frequency up to infity, in reality the rejection will weaken as the frequency goes up.
    • Highpass filters stop the signal from DC to a defined frequency called rejection frequency. It then allows the signal to pass through ideally to infinity. In practice however, the signal is attenuated again after a certain frequency.
    • Bandpass lets a signal through on a defined bandpass from Fmin to Fmax. The upper and lower rejection are also defined. Please note that in practice, the bandpass is repeating itself at around 3x Fmin to Fmax. However, Deti has designed solutions in order to push away the parasitic bandpass.
    • Bandstop filters, also called notch filters create a rejected frequency band within the filter's frequency range. It is often used to get rid of a parasitic signal (telecom frequencies such as 4G or 5G for example) within your application frequency range. As for band pass filter, there is parasitic bandstop a around 3x the initial notch.
