Waveguide Circulators and Isolators up to 170 GHz
Waveguide circulators and isolators are essential passive components for signal management in millimeter-wave and sub-terahertz applications. These components protect sensitive receiver stages and manage bidirectional signal flow in high-frequency systems where coaxial solutions become impractical. The portfolio covers frequency ranges extending to 170 GHz across multiple waveguide bands.
Technical Specifications
- Frequency coverage: Up to 170 GHz, spanning multiple waveguide bands and WR-codes
- Low-power variants: Optimized for receiver protection and measurement applications
- High-power options: Engineered for transmitter and amplifier stage integration
- Fullband designs: Single-unit solutions covering broad frequency ranges without switching
- Isolation performance: Exceeding 20 dB across specified operational bands
- Return loss (VSWR): Maintained across the entire frequency spectrum for system compatibility
Applications
- SATCOM: Component protection in uplink and downlink chains operating at Ka-band and higher frequencies
- Defense & Radar: Signal isolation in phased-array systems and precision measurement equipment
- 5G/6G Infrastructure: Frequency conversion and amplification chain protection in backhaul and fronthaul systems
- Automotive Radar: Millimeter-wave isolation in automotive sensing platforms
- Research & Development: Laboratory measurement systems requiring broadband isolation across extended frequency ranges
The availability of low-power, high-power, and fullband circulators and isolators reflects diverse requirements across frequency bands from X-band through W-band and into sub-terahertz regions. Each variant maintains consistent performance metrics suitable for cascaded system designs involving LNAs, HPAs, and frequency conversion stages.
