About Hefei Setsail Telecom Ltd. - Electric Components Supplier in China

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.

Product Range and Specialties of Hefei Setsail Telecom Ltd.

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.

Trade and Export Information - Hefei Setsail Telecom Ltd.

China is a major exporter of microwave passive components, and cavity power splitters are shipped to telecom equipment manufacturers in Southeast Asia, Europe and North America. The products fall under the HS chapter for electrical machinery (generally 8517), which requires exporters to provide a commercial invoice, packing list and, where applicable, a Declaration of Conformity for CE or FCC. Buyers typically request test reports conforming to IEC 60750‑1 or MIL‑STD‑461 for military applications. Standard Incoterms such as FOB Shanghai or CIF Los Angeles are used, with packaging in anti‑static bubble wrap inside wooden crates to protect the precise cavity tolerances. Container loads can accommodate several hundred units depending on packaging density, and moisture‑resistant pallets are common to prevent corrosion during sea transit.

Sourcing from Hefei Setsail Telecom Ltd. - Buyer Guidance

When sourcing these splitters, buyers should obtain a full specification sheet that confirms the 800‑2500 MHz bandwidth, 200 W power rating, VSWR, insertion loss per port and isolation figures. Requesting a test report from an accredited lab (e.g., SGS or TÜV) that includes S‑parameter measurements across the band helps verify performance. Verify that the supplier can provide RoHS compliance certificates and, if required for the target market, CE or FCC declarations. Samples are usually supplied in anti‑static packaging, and the minimum order quantity for production runs often starts at one full container load, though smaller batches may be negotiated with higher unit cost. Lead times for custom cavity designs can range from 30 to 60 days after order confirmation.

What frequency range do the splitters cover?

The listed splitters operate from 800 MHz up to 2500 MHz, covering most cellular, Wi‑Fi and broadcast bands. This bandwidth is standard for equipment that distributes RF signals in base‑station and antenna‑array applications.

What is the power handling capability?

Each model is rated for 200 W continuous power, which is typical for high‑power microwave distribution in telecommunications gear. The rating includes a safety margin defined by most manufacturers for sustained operation.

Which form factors are available?

The catalogue includes both round and square cavity housings. Both form factors are offered in 2‑way, 3‑way and 4‑way configurations to suit different panel layouts.

What performance specifications should be checked?

Buyers normally verify VSWR (≤ 1.5), insertion loss per output (0.5 dB‑2 dB) and isolation between ports (20 dB‑30 dB). These parameters are usually listed in the supplier’s data sheet and confirmed by laboratory test reports.

Which certifications are commonly required for these components?

Typical requirements include RoHS compliance, IEC 61000 electromagnetic compatibility testing, and CE or FCC declarations for export to Europe or the United States. Additional military specifications such as MIL‑STD‑461 may be requested for defense contracts.

How are the splitters packaged for shipment?

They are usually placed in anti‑static bubble‑wrap, boxed, and palletised inside wooden crates to protect the cavity dimensions during sea or air freight. The packaging complies with ISO 11607 standards for electronic components.

What are typical lead times and minimum order quantities?

Standard production lead time is 30‑60 days after order confirmation, depending on the selected configuration. The minimum order is often a full container load, although smaller trial quantities can be arranged on request.
