The 3-screw transformer is used to reduce mismatching, e.g. when matching horn antennas or other loads. It is also important for the generation of arbitrary reflections. As reactive elements the screws carry out the desired impedance transformation. The arrangement of the probes is slightly asymmetrical with respect to the flange planes. This enables better tuning in individual cases.
Design:
Aluminium module with LD quick-release connectors.
On the wide side of a rectangular waveguide there are 3 screws arranged along the center line at a distance of 3/8 * LAMBDA. The screws act as probes and can be screwed completely into the waveguide. There is an insert nut provided in the base section for mounting a support.
