Waveguide to Coax Adapters up to 170 GHz
Waveguide to coaxial adapters provide seamless integration between waveguide transmission systems and coaxial components across microwave and millimeter-wave frequency bands. The available portfolio spans frequencies from low-band applications up to 170 GHz, covering the complete range from WR2300 through WR5 waveguide standards. These passive interconnect solutions accommodate diverse system integration requirements in both laboratory and field deployment scenarios.
Technical Specifications
- Frequency Range: Broadband coverage from WR2300 (3.95–5.85 GHz) to WR5 (up to 170 GHz)
- Adapter Configurations: End launch, double-ridge, right-angle, microstrip, elliptical-to-rectangular, and circular-to-waveguide topologies
- Coaxial Interface Options: SMA, 3.5 mm, 2.92 mm, and 1.85 mm connectors depending on frequency band
- VSWR Performance: Typical values <2.0:1 across standard frequency bands, with optimized designs for critical applications
- Impedance: Standard 50 Ω characteristic impedance for RF signal path compatibility
- Construction Materials: Precision-machined aluminum or brass bodies with gold-plated contact surfaces
Applications
- SATCOM Systems: Ground station antennas and satellite communication terminals requiring broadband waveguide-to-coax transitions
- Defense and Military RF: Radar systems, electronic warfare (EW) equipment, and secure communication platforms operating across extended frequency ranges
- 5G/6G Infrastructure: High-frequency backhaul equipment and mmWave antenna assemblies utilizing waveguide-based feed networks
- Test and Measurement: Network analyzer calibration, antenna characterization, and RF component evaluation across millimeter-wave bands
The double-ridge adapter variants provide enhanced bandwidth performance compared to standard rectangular waveguide configurations, reducing the number of transition components required in broadband systems. Right-angle mechanical arrangements address space-constrained installations where direct end-launch mounting proves impractical.
