Microtech's Terminations, Medium Power  are engineered, designed, and manufactured "in house" utilizing computer aided design and manufacturing in our state-of-the-art production facilities.Microtech, Inc. medium power fixed terminations are designed where a matched load is desired to terminate a waveguide transmission line in a dissipative, nonreflecting component. These units require no additional cooling at the rated power level. The fins can be mounted vertically on the unit for optimum convection cooling when the unit is mounted vertically.
