USX

USX is Universal Substrate Box with pre-drilled holes for SMA or 2.92 connectors for circuits with microstrip or coplanar wiring. Equipped with all accessories, it allows fast clamping of any active and passive RF circuits of various thicknesses from 0.2 to 1.2 mm. The cap provides shielding and allows the bonding of additional attenuation materials to suppress waveguide vision. Assembly is very easy and quick and allows reuse with other substrates. Thanks to the precision ground blocks, perfect ground plane transition is ensured and the connector's center conductor does not need to be soldered.
