The C2-A12 Dual Directional Coupler is a high-performance RF coupler designed for Distributed Antenna Systems (DAS), wireless infrastructure, cellular networks, and broadband communication applications. Operating from 380 MHz to 3000 MHz, it provides accurate forward and reverse power measurements with high directivity, low insertion loss, and excellent low PIM performance. Featuring a three-section airline (slabline) design, the C2-A12 delivers reliable signal monitoring and network optimization while supporting high-power RF systems. Its rugged construction and broadband performance make it ideal for in-building wireless systems, RF testing, amplifier monitoring, and commercial communication networks.
