WR-15 Low Power Termination
The WR-15 Low Power Termination is a precision-engineered waveguide component that provides an exact precision match for terminating unused ports during VNA calibration and testing. It is specifically designed for the 50 - 75 GHz frequency range, serving as a critical building block in V-Band infrastructure.
Low-power terminations prioritize absolute minimum VSWR over heat dissipation, using a highly engineered, delicate absorbing element designed for milliwatt-level measurement accuracy. WR-15 spans the 50-75 GHz V-Band. Its 0.148" x 0.074" dimensions are the standard for 60 GHz commercial backhaul networks and inter-satellite links (ISL) in low earth orbit constellations.

Frequently Asked Questions
Can a low power termination be used for calibration?+
Yes. Low power terminations are frequently used as the "Load" standard during a Short-Short-Load-Thru (SSLT) calibration on a Vector Network Analyzer, requiring them to have near-perfect return loss (better than 30 dB).
How is WR-15 used in space applications?+
WR-15 is the standard for Inter-Satellite Links (ISL) in V-Band. Because there is no oxygen in space to absorb the 60 GHz signals, satellites can transmit massive amounts of data to each other using WR-15 feed networks and high-gain antennas without interference from Earth-based signals.
Are WR-15 components difficult to manufacture?+
Yes. At 75 GHz, the wavelength is only 4 millimeters. A manufacturing defect of just 0.1 mm inside a WR-15 component acts as a massive impedance mismatch. All RF Essentials WR-15 products undergo strict metrology and vector network analyzer testing.
