Core Positioning: "Low-Loss Signal Manager" and "Interference Barrier" in the 2.4GHz Band

　　In scenarios involving WiFi communication (802.11b/g/n/ac/6), Bluetooth connectivity (5.0/5.3), IoT sensing (ZigBee/LoRa), and industrial wireless control in the 2.4GHz ISM band (dedicated for industrial, scientific, and medical applications), devices need to overcome three core challenges: dense frequency band devices (coexistence of mobile phones/routers/sensors), sensitivity to signal loss in short-range communication (signal attenuation directly affects coverage distance), and high battery life requirements for low-power devices. The 2.4GHz dedicated RF circulator/isolation device, through its low insertion loss directional transmission design, achieves "low-loss output of transmitted signals, interference-free return of received signals, and isolation from interference from adjacent devices," building a "fidelity defense line" for 2.4GHz short-range wireless links and ensuring an optimal balance between data transmission rate, connection stability, and device battery life.

　　Three core advantages to meet the stringent requirements of the 2.4GHz band:

　　1. Ultra-low insertion loss: Ensuring signal transmission efficiency

　　Industry-leading loss performance: Insertion loss ≤0.3dB (typical value 0.2dB) across the entire 2.4~2.4835GHz band, far below the 0.5dB loss threshold of conventional devices, minimizing signal attenuation. For example, when used with a WiFi 6 router, coverage distance can be increased by 30% (from the usual 40m to 52m), and IoT sensor transmit power can be reduced by 20% (from 10dBm to 8dBm), directly extending device battery life (from 18 months to 24 months in AA battery powered scenarios);

　　Strong loss stability: Loss drift ≤0.05dB across the entire temperature range (-20℃~85℃), avoiding signal fluctuations caused by changes in ambient temperature, adapting to various temperature scenarios such as home, industrial, and outdoor use, ensuring WiFi performance. Consistent and stable video calls and Bluetooth audio transmission; High signal matching: VSWR ≤ 1.2, perfectly matching the 50Ω impedance commonly used in 2.4GHz devices, reducing signal reflection loss and ensuring data transmission rates (e.g., WiFi 5 devices can stably reach a peak rate of 866Mbps without rate attenuation).

　　2. High Isolation and Interference Immunity: Responds to interference from densely packed devices.

　　Strong Interference Suppression Capability: Isolation ≥25dB, effectively suppressing cross-interference within the 2.4GHz band—e.g., in home scenarios, when a WiFi router and Bluetooth speaker coexist, audio stuttering is avoided (stuttering rate reduced from 15% to below 0.5%); in industrial scenarios, the bit error rate of command transmission between wireless sensors and wireless controllers is ≤1×10⁻⁹, complying with the IEC 62368-1 communication equipment immunity standard;

　　Wide Bandwidth Suppression: In addition to the 2.4GHz main frequency band, interference suppression of adjacent 2.3GHz (LTE band) and 2.5GHz (5G NR supplementary band) is ≥20dB, avoiding cross-band signal crosstalk and adapting to environments where multiple wireless devices coexist (e.g., 5G phones, WiFi 6, and Bluetooth 5.3 devices operate simultaneously);

　　Complete Compliance Certifications: Passed Certified by CE (European wireless equipment standard) and FCC (US Federal Communications Commission), with radiated spurious emissions ≤-54dBm/Hz, ensuring no interference to peripheral devices and meeting market compliance requirements for consumer electronics and industrial equipment.

　　3. Miniaturization and Multi-Form Compatibility: Compatible with all types of 2.4GHz devices

　　Ultra-miniature package design: Supports SMT surface mount, with a minimum package size of 1.6×1.6×0.8mm (weight ≤0.5g), only 1/4 the size of traditional through-hole devices, adapting to the PCB layout requirements of miniaturized products such as IoT sensors (e.g., smart door lock sensors), Bluetooth headsets, and wearable devices (e.g., smart bracelets);

　　Multi-interface compatibility: Provides three mainstream interfaces: SMA (standard coaxial interface), U.FL (miniature coaxial interface), and IPEX (ultra-small coaxial interface), adapting to different antenna connection methods of devices—such as home WiFi routers (SMA interface external antenna), Bluetooth headsets (U.FL interface built-in antenna), and industrial wireless modules (IPEX interface onboard antenna);

　　Lightweight material selection: Uses a ceramic dielectric core + high-temperature resistant LCP (liquid crystal polymer) shell, balancing signal penetration (stable dielectric constant ≤9.8) and structural strength, and can withstand PCB... High-temperature soldering (260℃/10s), suitable for batch surface mount technology (SMT) production processes.

　　Bluetooth Connectivity: Adapting to Bluetooth 5.3 headphones/speakers, providing high isolation to avoid crosstalk with WiFi signals and ensuring lossless audio transmission (latency ≤30ms); reducing transmission power for Bluetooth BLE (Bluetooth Low Energy) devices, such as the Bluetooth communication module of smart bracelets, extending battery life from 12 months to 18 months, compliant with the Bluetooth Special Interest Group (SIG) 5.3 specification;
