Hi to all,
I am reading some splitters' datasheet, but can't find any infos related to the noise (like noise figure, system temperature, etc.).
I'm sending you a link with one of the datasheet; please tell me if I'm missing something.
Also, is it realistic to think it as a filter or attenuator's situation (so the effective attenuation=noise figure)?
Any lossy device adds the noise figure that equals to its loss in dB. But beware: as the other coupler or divider branch is connected somewhere, this can be a path of an interfering signal. Check for isolation and if some interfering signal can get into your low-noise reciver.
