Frequently Asked Questions
What is a low power waveguide termination?+
A low power waveguide termination is a compact matched load designed to absorb milliwatt-level RF signals at the end of a waveguide transmission line. These loads prevent signal reflections and are essential for calibrating network analyzers, power meters, and other precision test equipment.
What is the difference between low power and high power terminations?+
Low power terminations are compact, lightweight units designed for test and measurement setups, typically handling milliwatt-level signals. High power terminations incorporate heat-dissipating features such as larger bodies and cooling fins, and are designed for transmitter testing and high-power system applications.
What frequency range do RF Essentials terminations cover?+
RF Essentials manufactures waveguide terminations covering frequencies from 18 GHz (Ka-Band) through 500 GHz (sub-THz), available in standard WR sizes from WR-28 through WR-03.
Are RF Essentials terminations made in the USA?+
Yes. All RF Essentials terminations are manufactured in the United States at our facility in St. Petersburg, Florida. Domestic production ensures strict quality control and fast lead times.
