Product Description
The WMADC-0.7-2.7-40DB-SERIES is a high-power 40 dB directional coupler covering 690 to 2700 MHz, supporting key cellular, LTE, and wireless infrastructure bands. Built on an air dielectric coaxial structure, this design delivers low insertion loss, excellent power handling, and exceptional directivity for accurate forward and reverse power discrimination. Unlike many broadband couplers that prioritize ultra-flat coupling, this model is engineered to maximize directivity across the band, ensuring cleaner separation between forward and reflected signals. In most real-world systems, coupling variation is easily calibrated out, while poor directivity cannot be corrected—making this approach better aligned with high power measurement accuracy and system protection. Typical applications include RF power monitoring, transmitter protection, VSWR measurement, distributed antenna systems (DAS), base station infrastructure, and general-purpose RF test setups requiring reliable sampling of high-power signals. The series is configurable in single or dual configurations. The input connector is offered with a standard N-Female, or optionally an N-Male for direct amplifier connection— eliminating unnecessary adapters, reducing mismatch, and preserving system integrity at high power.
