Overview

The passive waveguide portfolio includes fixed attenuators, couplers, filters, Faraday isolators and waveguide-to-coaxial adapters. Selected component families reach 500 GHz; each function has its own band and waveguide range.

Additional product details

The High Precision Passive Waveguide Components lineup includes fixed attenuators and directional couplers up to 500 GHz, plus waveguide filters, diplexers, Faraday isolators, straight sections, bends, and waveguide-to-coaxial adapters.

Along with waveguide-to-coaxial adapters supporting connectors down to 0.6mm, our components empower rapid and reliable integration.

Waveguide size is the first constraint on any of these choices, not frequency: a WR-2.2 attenuator and a WR-19 attenuator cannot be swapped, so the band plan for the chain has to be fixed before the component list is. Where a chain crosses bands, the waveguide-to-coaxial adapters are the transition point worth specifying early.

Key Capabilities & Applications

Attenuation and coupling

Fixed attenuators and directional couplers cover 40–500 GHz. Standard attenuation values are 3 / 6 / 10 / 20 / 30 / 40 dB, with model-dependent power handling up to 10 W in lower bands.

Filtering and isolation

Filters cover 26.5–330 GHz with band-pass, low-pass, high-pass or band-stop forms. Faraday isolators cover 50–220 GHz; insertion loss is as low as 1.0 dB on applicable models.

Mechanical signal-chain routing

Waveguide-to-coaxial adapters, straight sections, tapers, twists and bends support interconnection. Select waveguide size, flange and connector for the intended band.

All capabilities and operating conditions

High-power attenuation

Fixed attenuator modules list standard 3, 6, 10, 20, 30, and 40 dB values with model-dependent power handling up to 10 W.

Coupling and filtering options

Directional couplers, dual-directional couplers, waveguide filters, and diplexers support measurement and routing functions.

Source protection

Compact Faraday isolators cover 50 to 220 GHz for source protection and signal isolation.

Common applications

  • Signal-level control
  • Measurement pickoff and monitoring
  • Waveguide frequency shaping
  • Source protection and transitions
