Hefei Setsail Telecom Ltd.

China is the origin of Hefei Setsail Telecom Ltd., which currently lists five active products in its catalogue. All five items belong to the electric components and power conditioning equipment categories and are described as cavity power splitters operating from 800 MHz to 2500 MHz with a rated power of 200 W. The catalogue includes round and square cavity designs with 2‑way, 3‑way and 4‑way configurations. Each model is specified by its physical form (round or square) and the number of output ports. The supplier’s listing does not provide additional technical data such as insertion loss or isolation.

The five products are titled 800‑2500 MHz Cavity Round 200 W 2‑Way Power Splitt, 800‑2500 MHz Cavity Round 200 W 3‑Way Power Splitt, 800‑2500 MHz Cavity Round 200 W 4‑Way Power Splitt, 800‑2500 MHz Cavity Square 200 W 3‑Way Power Split and 800‑2500 MHz Cavity Square 200 W 4‑Way Power Split. The naming indicates a frequency range that covers most cellular, Wi‑Fi and broadcast bands, a power handling of 200 W, and a cavity construction that typically provides high isolation between ports. No further specifications such as VSWR, insertion loss, or material composition are listed.

The catalogue focuses exclusively on microwave cavity power splitters. In the RF component market, splitters of this type are usually built from copper or aluminum cavities with plated waveguide or coaxial interfaces, delivering insertion loss between 0.5 dB and 2 dB per branch and isolation of 20 dB to 30 dB for 2‑way units, with higher isolation for 3‑ and 4‑way configurations. Typical industry grades include IEC 61000‑4‑2 for electromagnetic compatibility and RoHS compliance for lead‑free construction. Buyers often request data sheets that list VSWR (typically ≤ 1.5), power‑handling margin (often 10 % above the rated 200 W), and mechanical dimensions such as cavity height (generally 30 mm‑50 mm). The round versus square form factors affect mounting options, with square units commonly used in panel‑mount chassis.
