Torsional Joints
Microtech's Torsional Joints are engineered, designed, and manufactured "in house".
Microtech, Inc. Torsional Joints will help shield your system from torsional stresses. Low VSWR, low Insertion Loss, and High Power Handling are achieved through the use of infinitely variable one-quarter wavelength (1/4) steps. Presenting a more economical solution than a rotary joint, our rugged construction affords you long life under extreme operating conditions. Microtech, Inc. Torsional Joints feature minimum phase WOW, stable phase linearity and designs that lend themselves to high power applications, all at a reasonable cost. If you need a special configuration just contact the factory or our area representative with your requirements. Our complete in-house engineering and production facility is at your disposal.
