Abstract

In order to reproduce coax-to-waveguide transitions with a low Voltage Standing Wave Ratio (less than 1.05), it is critical that tight dimensional tolerances be maintained during manufacturing. On a production basis this involves high costs and time consumption. This device allows the tolerances for manufacturing transitions to be considerably reduced, by introducing a fine tuning adjustment which can easily be implemented on a production line.

Tunable Coax To Waveguide Transition

In order to reproduce coax-to-waveguide transitions with a low Voltage Standing Wave Ratio (less than 1.05), it is critical that tight dimensional tolerances be maintained during manufacturing. On a production basis this involves high costs and time consumption. This device allows the tolerances for manufacturing transitions to be considerably reduced, by introducing a fine tuning adjustment which can easily be implemented on a production line.

The fine tuning adjustment consists of a dielectric screw, which is threaded into the dielectric sleeve of the transition to vary the air gap at the end of the probe. The screw insertion depth is adjusted to provide the minimum Voltage Standing Wave Ratio, and is either cut or staked to the waveguide wall to finalize the design.
