Dual Directional Coupler is a widely used microwave device mainly used for power measurement and signal analysis of electromagnetic signals. The characteristics of broadband high-power dual directional couplers are as follows:
1. High power: The materials and structures used in the coupler are special, and they can withstand relatively large power outputs.
2. Dual directional: The coupler has good coupling effect in both directions and can achieve forward and reverse signal transmission.
3. Low loss: The internal loss of the coupler is relatively small, which can effectively improve the transmission quality of the signal.
Qualwave Inc. has multiple models of dual directional couplings, and all models of products have the characteristics of broadband, high power, and low insertion loss. Now, We introduce one of them, with frequencies ranging from 9kHz to 67GHz, 3500W. Its widely used in amplifiers, broadcasting, laboratory testing, communication, and other applications.
