High-Power and Rugged Design
The combiner is designed to handle 33 W continuous power per input port, with 150 W power handling at the common port. For pulsed or peak-power applications, it supports up to 130 W per input port and 500 W at the common port.
In addition to its RF performance, the unit incorporates a high-shielding enclosure to minimize RF leakage and interference. The IP66-rated mechanical design provides protection against dust and water ingress, making the combiner suitable for demanding outdoor and harsh-environment applications.
RF Performance Verification
Each unit is tested to verify key RF parameters, including insertion loss, VSWR, isolation, amplitude balance, and phase balance across the specified frequency range.
