Engineered for precise signal monitoring and power management within high-frequency transmission paths, these professional Directional Couplers serve as a fundamental component in 5G infrastructure and microwave systems. These 3-port or 4-port passive devices are strategically deployed to sample a specific fraction of the forward-traveling RF power while ensuring the cleanest possible signal environment by utilizing internal electromagnetic coupling structures that maintain high isolation between the primary transmission line and the coupled output port.

Key features include an ultra-wide frequency response from 600 MHz up to 40 GHz and a range of standard coupling values, including 6 dB, 10 dB, 20 dB, and 30 dB. Engineered for carrier-grade reliability, they are housed in precision-machined aluminum or stainless steel enclosures that provide exceptional thermal stability and a low insertion loss (≤ 0.2 dB) on the main line. Built with precision-machined mechanical interfaces—including N-Type, SMA, and 4.3-10—these rugged units provide a secure, low-loss solution for real-time power leveling, antenna VSWR monitoring, and laboratory-grade signal analysis where high directivity and flat frequency response are essential.
