FB1003 is a general purpose 1GHz bandpass filter.

It’s a lumped element filter housed in a standard Asartech FG1002 housing, i.e., 39.25 x 16.7 x 11mm aluminum box. The input and output connectors are standard SMA.

The unit is intended for narrowband applications up to 100MHz, as well as harmonic filtering for fixed 1GHz reference frequency sources.
