High-Frequency RF Isolators and Circulators for Telecommunications

　　In the era of 5G advanced and pre-6G deployment, high-frequency signal transmission in telecommunications networks demands unprecedented precision—where even 0.1dB of insertion loss can disrupt entire data links, and signal interference can cripple latency-critical applications. Our high-frequency RF isolators and circulators, engineered for 18GHz to 110GHz bands, serve as the "signal guardians" of telecom infrastructure, delivering ultra-low loss, ultra-high isolation, and rugged reliability to power the next generation of connectivity.

　　Core Technologies: Redefining High-Frequency Performance

　　Ferrite Nanostructure Optimization

　　Adopting yttrium iron garnet (YIG) ferrite with 50nm grain refinement, our devices achieve ≤0.4dB insertion loss at 28GHz—30% lower than industry averages. The proprietary magnetic bias design ensures isolation ≥22dB across the entire operating band, effectively suppressing reflected signals that cause amplifier burnout in 5G base stations.

　　Planar Integration Compatibility

　　Featuring a compact footprint (as small as 3.2mm×3.2mm) and surface-mount (SMT) packaging, these components seamlessly integrate into phased array antennas and small-cell transceivers. The gold-plated waveguide interface ensures VSWR ≤1.2:1, minimizing signal mismatch in high-density telecom racks.

　　Thermal Management Breakthrough

　　The aluminum nitride (AlN) substrate with 170W/m·K thermal conductivity dissipates heat 5x faster than traditional alumina, enabling continuous operation at 50W CW power without performance degradation—critical for 5G macro base stations operating in extreme temperature environments (-40℃ to +85℃).

　　Telecom-Specific Applications

　　5G NR Base Stations

　　Deployed in sub-6GHz and mmWave (24/28/39GHz) sectors, our circulators enable full-duplex operation by isolating transmit and receive paths, reducing intermodulation distortion (IMD) to -150dBc and extending amplifier lifespan by 2x.

　　Data Center Interconnects (DCI)

　　In 400G/800G optical transport networks, the isolators suppress laser source reflections to < -60dB, ensuring BER (Bit Error Rate) < 1e-12 for ultra-reliable cloud data transmission.

　　Satellite Ground Terminals

　　The hermetically sealed (IP68) variant withstands 1000-hour salt spray testing, maintaining stable performance in maritime and coastal telecom hubs. Its low phase variation (<±1°) ensures precise beamforming in VSAT systems.

　　Reliability & Compliance

　　Industry Certifications: CE, RoHS 2.0, REACH, and Telcordia GR-486 qualified, with shock/vibration resistance per IEC 60068-2-27/29.

　　Long-Term Stability: <0.2dB insertion loss drift over 10,000 hours of operation, validated through accelerated life testing.

　　Customization Capabilities: Tailored frequency bands (18-110GHz), connector types (SMA, 2.92mm, waveguide), and power ratings to match specific telecom infrastructure designs.

　　Future-Ready for 6G Evolution

　　Our next-gen devices integrate AI-driven monitoring chips to real-time report temperature and isolation metrics via IoT protocols, enabling predictive maintenance in autonomous telecom networks. The upcoming 140GHz model will support terahertz (THz) communication trials, laying the groundwork for 6G's 1Tbps data rates.
