Shielded housings protect RF circuits, connectors

Oct. 13, 2020
The TekBox TBRFH1 series of RF shielded housings provide convenient boxes for RF circuits in development or production.

Saelig Company, Inc. (Fairport, NY) has announced the availability of the TekBox TBRFH1 series of RF shielded housings, which are designed for enclosing prototype RF building blocks operating up to 6 GHz. The housings consist of a 1-inch aluminium profile square cross-section tube with a choice of mechanically matching RF connectors on each end.

A range of RF connector combinations and housing lengths are available, with optional feed-through capacitors. The housings come with RF absorbing pads to suppress coupling and cavity resonance. Solderable sheet metal ground pads, sandwiched between the connectors and the aluminium profile, simplify establishing a ground connection.

The TBRFH1 housings come in 35-, 50-, and 100-mm lengths; RF connector choices include BNC male and female, N-type male and female, and SMA male and female. An RF PCB can either be inserted horizontally or diagonally in the housings, depending on the space requirement of the circuit.

Manufactured by Vietnam-based Tekbox Digital Solutions, the TBRFH1 series of RF shielded housings is available now from authorized North American distributor Saelig Company, Inc. For additional information, contact Saelig at 888-7SAELIG or visit
