Import 300w C Band 4.0~8.0ghz Rf Coaxial Circulators — Buy in wholesale FOB from Supplier in China

The UIYBCC5654A4T8NF is a coaxial circulator covering the full C-band from 4.0 to 8.0 GHz, rated for 300 W forward and reverse power with N-type female connectors. Key parameters include 0.6 dB insertion loss, 16 dB isolation, and 1.4:1 VSWR across the octave bandwidth, housed in a 56 by 54.3 by 36 mm package. This octave-spanning performance distinguishes it from narrower-band circulators, though the broader bandwidth results in lower isolation compared to tuned narrowband designs.

C-band coaxial circulators in this frequency and power class typically utilise yttrium iron garnet (YIG) or substituted garnet ferrites with biasing magnets optimised for 4~8 GHz gyromagnetic resonance. The N-F coaxial interface is standard for medium-power RF test equipment and radar systems, with the 56 mm housing suggesting an internal coaxial-to-stripline transition with external heat sinking fins. Typical construction includes brass or aluminium alloy body with passivated or nickel-plated finish, and internal impedance matching tapers to maintain VSWR below 1.5:1 across the octave.

Target applications include radar transmit-receive switches, electronic warfare systems, satellite ground station uplinks, and wideband test setups where a single circulator must cover multiple C-band allocations. The octave bandwidth suits frequency-hopping or swept-frequency systems that would otherwise require multiple narrowband circulators. Buyers should discuss frequency-specific performance, as isolation and VSWR vary across 4~8 GHz, and confirm whether Uiy Inc. provides segment-specific test data or only centre-band guarantees.

Uiy Inc. operates from No. 8, Lane 1, Xintun East Zone, Longgang District, Shenzhen, 518172, Guangdong, China, within one of the world's densest concentrations of RF and microwave manufacturing. The company is listed at Harbor trust tier but shows a 0.00 percent response rate and zero average response hours, indicating no recorded buyer engagement through the platform. No information on factory size, engineering staff, revenue, or client base is available in the source profile.

The listing focuses on a coaxial circulator with full octave coverage, suggesting engineering capability in broadband ferrite device design rather than simple assembly. However, the lack of response history means buyers cannot assess quotation speed, technical support depth, or sample provision reliability from platform data alone. Direct outreach with specific technical questions is recommended to evaluate supplier competence before purchase commitment.
