Waveguide Couplers for Sub-Terahertz Frequencies up to 325 GHz
Waveguide directional couplers are essential components in RF test systems, power monitoring, and signal distribution architectures where coaxial alternatives introduce excessive insertion loss. The latest coupler portfolio extends up to 325 GHz, addressing the growing demand for precision measurement solutions in mmWave and sub-terahertz frequency bands for 6G prototyping, advanced SATCOM systems, and millimeter-wave radar development.
Technical Specifications
- Frequency Coverage: WR28 to WR3 waveguide standards, covering frequencies from X-band through 325 GHz
- Coupler Architectures: Broadwall configurations (WR650–WR28), crossguide designs (WR430–WR10), and single/dual directional loop couplers (WR650–WR90)
- Coupling Characteristics: Directional performance with controlled VSWR and isolation for precision measurement applications
- High-Power Variants: Custom implementations for elevated RF power levels in HPA and transmit chain integration
- Customization: Tailored solutions for specialized coupling ratios, impedance matching, and form factors
