10-67 GHz 20 dB Directional Coupler (Coaxial, Leader-MW)
The Leader-MW 10-67 GHz 20 dB directional coupler is a precision microwave component engineered for wideband signal monitoring, power sampling, and network analysis across the full Ka, Q, U, V, and E frequency bands. Covering an exceptionally broad operating range from 10 GHz to 67 GHz, this coaxial coupler delivers a nominal coupling factor of 20 dB with tight flatness, ensuring consistent performance across its entire bandwidth.
Designed with high directivity and low insertion loss, the coupler enables accurate forward and reflected power measurement with minimal disturbance to the main transmission path. Its robust coaxial construction provides excellent VSWR characteristics and reliable RF shielding, making it suitable for demanding test-and-measurement setups, radar systems, satellite communications, and 5G/mmWave research applications.
The component features standard coaxial interfaces for easy integration into existing test benches and system architectures. Its compact, durable housing ensures stable operation under varying environmental conditions, while maintaining high power handling capability and repeatable performance.
Ideal for engineers requiring precise signal sampling in broadband systems, the Leader-MW 10-67 GHz 20 dB directional coupler combines wideband coverage, superior electrical performance, and mechanical reliability—delivering a cost-effective solution for advanced microwave and millimeter-wave applications.
