Couplers up to 500 GHz

Waveguide Couplers up to 500 GHz

Waveguide couplers from bq-microwave enable precise signal sampling and power measurement in the RF/microwave and mmWave range. With frequency coverage from standard waveguides to high-frequency WR2.2 dimensions, our couplers address a broad spectrum of modern applications – from laboratory test and measurement to industrial HPA and LNA systems.

Key Features

• Frequency range: DC to 500 GHz (WR28 to WR2.2)
• Directional couplers with high coupling accuracy and directivity
• Broadwall, crossguide and loop coupler configurations
• Low insertion loss and optimized VSWR performance
• Single and dual versions for flexible system integration

Applications

• High-frequency test and measurement and signal monitoring
• SATCOM, defense and aerospace systems
• 5G/6G network test infrastructure
• FMCW radar, ADAS and automotive mmWave
• Power control in high-power RF systems
• Calibration and characterization of HPA modules

Our directional couplers provide optimal directivity for precise forward and reverse measurements, while broadwall couplers combine high power capacity in compact designs. Crossguide couplers offer minimal insertion loss and space efficiency – ideal for integrated system solutions. Loop couplers achieve highest isolation and are particularly suited for high-power applications and system calibration.

In addition to our extensive standard portfolio, we develop custom couplers for specific frequency bands, defined coupling values and mechanical requirements. Our certified manufacturing guarantees consistent quality. Contact us for technical consultation and custom solutions.
