Einführung in das Hauptprodukt
Diese 27.5-30GHz Directional Coupler is specifically engineered for the demanding requirements of millimeter-wave systems. By utilizing advanced thin-film technology and precise mechanical tolerances, the device achieves a highly accurate 10dB Kopplung with excellent flatness across the entire band. Its design is optimized to maintain electrical performance under the high power densities associated with 50W Ka-band transmitters, making it an ideal choice for power monitoring and feedback loops.
The coupler’s low VSWR (≤1,5:1) ensures minimal impedance mismatch, protecting sensitive GaN power amplifiers and high-frequency transceivers. The ruggedized construction and passivated finish provide long-term reliability in both laboratory environments and fixed satellite ground stations, where high-frequency signal integrity is paramount.

Häufig gestellte Fragen
- What connector type is recommended for this 30GHz coupler?
- For frequencies up to 30GHz, we recommend 2.92mm (K-type) connectors as they provide superior mode suppression and lower VSWR compared to standard SMA interfaces at these frequencies.
- How stable is the coupling value over the 27.5-30GHz Reichweite?
- The device is designed for a coupling flatness of ±0.7dB, ensuring that your power measurements remain consistent across the entire operational bandwidth.
- Can this coupler handle 50W in a vacuum or high-altitude environment?
- While rated for 50W under standard conditions, high-altitude or vacuum deployments require additional thermal considerations; please contact our engineering team for custom space-grade variants.
- Does this coupler support bi-directional monitoring?
- This specific model is a Richtkoppler (sampling one direction). For simultaneous forward and reverse monitoring, we can offer a Dual-Directional version in the same frequency band.
