Its a very sharp pass-band filter, you have to specify frequency at the time of ordering.

It attenuates a signal a few MHz above your carrier and a few MHz below. This "a few MHz" can also be less than 1MHz so very sharp indeed.

These things can be for example used in receivers to block a very sharp local station. Or for combining multiple transmitters for one single antenna system.

Big, heavy and not cheap.
