The Amplifier Research DC3010 is a dual directional coupler engineered for real-time monitoring of forward and reflected power in RF power systems. Operating across 10 kHz to 1 GHz, it delivers ultra-broadband performance with minimal insertion loss, making it ideal for integration into test benches and communication system validation platforms. The coupler handles 100 watts CW and 200 watts peak power while maintaining exceptional directivity and coupling flatness, enabling accurate power measurement via oscilloscopes, voltmeters, power meters, and spectrum analyzers.
