LDC-0.4/20-20S 0.4-20Ghz 20dB coupler
| Leader-mw | Introduction to 0.4-20G 20dB diretional coupler |
Chengdu Leader microwave（LEADER-MW) LDC-0.4/20-20S wideband coupler, the perfect solution for system applications requiring external leveling. Focusing on low VSWR, high directivity, and rugged construction, these couplers are designed to provide excellent performance and reliability in a variety of environments.
Our LDC-0.4/20-20S wideband couplers are engineered to provide low voltage standing wave ratio (VSWR), ensuring minimal signal reflections and maximum power transfer efficiency. This feature is critical to maintaining signal integrity and minimizing potential signal loss, making these couplers ideal for critical system applications where accuracy and reliability are critical.
In addition to low VSWR, our couplers offer high directivity, allowing for accurate measurement and monitoring of power levels within a system. Our couplers accurately isolate and measure forward and reverse signals, allowing engineers and technicians to confidently assess system performance and make informed adjustments as needed.
