WC Series • X-Band (8.20 – 12.4 GHz)
FT-RF WR90 Waveguide to Coaxial Adapter
FT-RF WR90 Waveguide to Coaxial Adapters are industry-standard interconnect components engineered for high-efficiency mode conversion across X-band frequencies (8.20 GHz to 12.4 GHz). They convert rectangular waveguide TE10 propagation modes into 50 Ω coaxial transmission lines with ultra-low insertion loss.
Precision-machined from high-grade aluminum and brass alloys, the WR90 adapter series is widely deployed in NEXRAD weather radar networks, maritime navigation systems, and military EMC compliance test chambers. Standard choices include N-type and SMA female interfaces with UG-39/U flanges.
🛠️ Engineering & Customization Options
Tailored structural designs and custom launch options:
- Flange Configuration: UG-39/U / FDP100 cover flange.
- Coaxial Interface: Precision N-Type / SMA Female (50 Ω).
- Custom Launch: Right-angle or end-launch profiles.
