Terminations, Low Power
Microtech's Terminations, Low Power are engineered, designed, and manufactured "in house".
Microtech, Inc. low power fixed terminations are designed where a matched load is desired to terminate a waveguide transmission line in a dissipative, nonreflecting component. Also used as standard matched load for the termination of waveguide components.
