Terminations, Medium Power Double-Ridged
Microtech's Terminations, Medium Power Double-Ridged are engineered, designed, and manufactured "in house".
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.
