Features & BenefitsSeries WTR fixed terminations featuring Millitech technology are designed to have a maximum VSWR ranging from 1.03:1 in the WR-42 to WR-22 frequency ranges to 1.5:1 in the WR-06 and WR-05 frequency ranges. Series TLD tunable loads utilize a metric micrometer tuning mechanism which allows the microwave absorber to be positioned within the guide while maintaining a constant magnitude of reflection coefficient. Series TLD tunable loads have a nominal VSWR as low as 1.05:1 to 90 GHz, are useful for the precise measurement of small reflections in transmission lines. Series TSC tunable shorts consist of movable, non-contacting choke plungers within a straight section of waveguide.
