TBRFH1 SERIES
RF HOUSINGS
The TBRFH1 series of RF housings are ideal for prototyping RF building blocks operating up
to 6 GHz. The housings consists of a 1 inch aluminium profile with mechanically matching RF
connectors on each end. The user can select a wide range of RF connector combinations,
various housing lengths and 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 the
ground connection.

4 Application hints
Provide exposed ground copper on your PCB to solder it to the ground connection pads.
Always solder the centre pins of the RF connectors first. Bend the wings of the ground
connection pads to reach the exposed ground copper of the PCB.
The PCB can either be inserted horizontally or diagonally, depending on the space
requirement of your circuit.
Don´t overturn the screws in order to avoid damaging the threads of the aluminium profile.
Ensure that the screws are sitting correctly, before tightening it. In case of a damaged thread,
repair it by applying a thin line of epoxy onto the affected thread.
