Core Positioning: "Frequency-Dedicated Signal Manager" and "Anti-Clutter Barrier" for Millimeter-Wave Radar

　　In scenarios such as intelligent driving vehicle-mounted millimeter-wave radar (77/79GHz), industrial high-precision detection radar (24/60GHz), and security low-altitude monitoring radar (24/77GHz), millimeter-wave radar needs to overcome three core challenges: short wavelength and easy attenuation (rapid signal loss at millimeter-level wavelengths), narrow beam and high directivity requirements (detection angle ≤5°), and numerous scene clutter (multi-radar collaboration in vehicles / industrial metal interference / security environment reflections). Dedicated RF circulators/isolators, as core passive components of millimeter-wave radar, achieve "precise beam focusing, uninterrupted signal return, and effective suppression of environmental clutter" through optimized design for directional transmission in the millimeter-wave band. This builds a "high-resolution detection defense line" for millimeter-wave radar, ensuring accurate measurement of target distance, angle, and velocity.

　　Three core advantages exclusive to millimeter wave technology, adapting to the stringent requirements of radar systems:

　　1. Customized performance for millimeter wave frequency bands: Ensuring high-resolution detection

　　Full-scenario frequency band coverage: Precisely adapts to the core frequency bands of millimeter wave radar—76~81GHz for automotive applications (meeting short-range high-precision/long-range detection needs, such as 77GHz long-range ACC, 79GHz short-range BSD), 24~24.25GHz (near-range positioning) and 57~64GHz (high-resolution detection) for industrial/security applications, compatible with MIMO multi-channel millimeter wave radar architecture, VSWR ≤1.25;

　　Ultra-low insertion loss: Typical insertion loss for millimeter wave frequency bands ≤0.5dB (77GHz band) and ≤0.6dB (60GHz band), minimizing short-wavelength signal attenuation and extending radar detection range (77GHz automotive radar can support 200m+ long-range detection, 60GHz industrial radar can achieve 0.1m). High-precision positioning; Ultra-high isolation and interference immunity: Isolation ≥28dB (79GHz band), ≥25dB (24GHz band), effectively suppressing crosstalk between adjacent millimeter-wave radars (such as the coordinated operation of vehicle-mounted forward + side and rear radars) and environmental clutter interference (metal reflection waves in industrial scenarios, rain and snow clutter in security scenarios), keeping the target misidentification rate below 0.1%. 2. Reliable Adaptability for Various Scenarios: Covering Millimeter-Wave Applications in Multiple Fields

　　Automotive-Grade Environmental Tolerance: Complies with AEC-Q200 automotive-grade certification, operating temperature range -40℃~125℃ (suitable for summer sun exposure and winter cold), vibration resistant (10~2000Hz, 196m/s²), shock resistant (500m/s², 1ms), compatible with automotive radar module installation environments in the "engine compartment/bumper," with a lifespan exceeding 10,000 hours;

　　Industrial-Grade Protection Upgrade: IP67 protection rating (dustproof and waterproof), resistant to industrial workshop dust, oil, and coolant corrosion, operating temperature -30℃~105℃, suitable for the long-term continuous operation requirements of automated production lines such as "robotic arm positioning radar" and "conveyor belt foreign object detection radar," complying with IEC 60068-2 industrial environmental standards;

　　Security-Grade All-Weather Adaptability: Salt spray resistant (500-hour neutral salt spray test), UV resistant (UVB-313 lamp 1000) (After 24-hour aging test), it is suitable for outdoor perimeter monitoring and low-altitude drone detection radar, maintaining stable performance and a detection accuracy of ≥98% even under heavy rain, heavy snow, and high temperature exposure.

　　3. Compact Integrated Design: Adapted to the Miniaturization Needs of Millimeter-Wave Radar

　　Ultra-Miniature Packaging: Supports SMT surface mount, minimum package size 2.0×2.0×0.8mm (77GHz band), weight ≤1g, suitable for palm-sized module designs of automotive millimeter-wave radar (e.g., forward-facing radar module volume ≤50cm³), reducing volume by 60% compared to traditional metal packaging;

　　Multi-Channel Integration: Supports 2/4-channel integrated design (e.g., 79GHz short-range radar dual-channel module), the integrated volume is 35% smaller than single-channel combinations, reducing radar module wiring complexity and improving signal synchronization (phase difference between channels ≤2°);

　　Lightweight Materials: Utilizes a ceramic dielectric core + high-temperature resistant engineering plastic shell (automotive-grade PPS material), balancing millimeter-wave signal penetration and structural strength, suitable for the lightweight requirements of UAV-borne millimeter-wave radar (single radar weight ≤100g).

　　Empowering Millimeter-Wave Radar Across All Scenarios: Key Support from "Precise Detection" to "Safe Decision-Making"

　　In the field of industrial automation: 24GHz millimeter-wave radar, combined with the anti-metal interference characteristics of components, achieves 0.05m-level precise positioning of robotic arms and workpieces; 60GHz high-resolution radar, relying on low-loss design, completes real-time detection of metal foreign objects on conveyor belts (identifying foreign objects with a diameter ≥5mm), complying with IEC 61508 industrial safety standards;

　　In the field of security monitoring: 24GHz perimeter radar, with its weather-resistant design, achieves accurate identification of intruding targets (personnel/vehicles) within a 5km range; 77GHz low-altitude radar, relying on its narrow-beam directional characteristics, effectively detects targets within a 1km range. Low-altitude unmanned aerial vehicles (UAVs) capable of identifying targets with a wingspan ≥ 0.3m, conforming to GB/T 35658 security radar standard.
