10-dB Directional Coupler, 8 to 40 GHz

Supports broadband microwave signal sampling, power monitoring, RF integration, and test and measurement setups where a stronger coupled output is needed.

20-dB Directional Coupler, 8 to 40 GHz

Supports broadband RF sampling and microwave power monitoring where a moderate coupled sample is required with low insertion loss.

30-dB Directional Coupler, 8 to 40 GHz

Supports low level broadband signal sampling and power monitoring where minimal disturbance to the main RF path is required.

Cross-Guide Directional Couplers

Waveguide directional couplers for sampling RF power in waveguide systems while maintaining mainline path integrity. Available in terminated and 4 port configurations for single direction or bidirectional power monitoring.

Multihole Directional Couplers

Waveguide directional couplers for forward and reflected power monitoring, calibration reference points, and built in test functions in payload and TT&C architectures.
