The invention relates to a switchable band-pass filter. In particular, the invention relates to a narrowband switchable band-pass filter over a broad frequency band with two filter elements (including microstripline technology, suitable for use as a cosite filter with a compact structure, which is particularly suitable for efficient mass production and robust in operation. The two filter elements in this context are coupled to one another, on the one hand via a switchable coupling device and, on the other hand, via a direct electromagnetic interaction. |
