WR90 Waveguide to Coaxial Adapter (8.2 GHz to 12.4 GHz)
FT-RF WR90 Waveguide to Coaxial Adapters are precision-machined interconnect solutions designed for X-band microwave systems. These adapters facilitate low-loss transitions between WR90 rectangular waveguides and coaxial interfaces (SMA or N-type). Available in multiple flange configurations (UBR/UG-39U, PBR) and specialized Half-height (1/2) versions, each unit is engineered to maintain superior Signal Integrity and low VSWR performance.
