Core Positioning: The "Data Fidelity Guaranteeer" and "Interference Filter" of the Test Link In scenarios such as R&D testing of RF devices, production calibration of electronic equipment, and field testing of communication systems, RF test instruments (such as spectrum analyzers, signal generators, and network analyzers) must overcome three major challenges: high measurement accuracy requirements (error ≤ 0.1dB), complex signal environments (multi-band signal superposition), and diverse test scenarios (laboratory/production line/outdoor). Dedicated RF circulators/isolators, as core passive components of these instruments, achieve "distortion-free test signal output and zero-crosstalk feedback signal return" through calibration-grade unidirectional signal transmission, building a "precision protection wall" for the measurement link and ensuring the accuracy of measurements of key parameters such as power, frequency, and impedance.

　　Three core advantages to meet the stringent requirements of RF test instruments:

　　1. Calibration-grade RF performance: Ensuring measurement data accuracy

　　* Ultra-low loss and high stability: Insertion loss ≤0.3dB (typical value 1-40GHz), and loss drift ≤0.05dB/℃, minimizing the impact of signal attenuation on power measurements, suitable for the weak signal capture requirements of high-precision power meters and spectrum analyzers;

　　* Ultra-high isolation and anti-interference: Isolation ≥35dB, effectively suppressing stray signals in the test environment (such as interference from adjacent frequency bands and internal instrument noise) and TX/RX port crosstalk, controlling measurement errors within ±0.02dB, conforming to the ISO/IEC 17025 calibration laboratory standard;

　　* Wide band and high matching: Covering the entire RF band from DC to 67GHz (including microwave and millimeter wave), VSWR ≤1.2, compatible with the multi-port calibration requirements of network analyzers, supporting accurate measurement of key indicators such as S-parameters and impedance.

　　2. Full-Condition Stability: Adaptable to Multiple Testing Environments

　　Laboratory-Grade Temperature Stability: Operating temperature range -20℃ to 85℃, temperature coefficient ≤0.001dB/℃, suitable for long-term calibration testing in constant temperature laboratories (such as 1000-hour stability testing for device development);

　　Production Line-Grade Interference Immunity: Electromagnetic compatibility (EMC) conforms to EN 61326-1 standard, resistant to radio frequency radiation interference (10V/m, 80-1000MHz), suitable for complex electromagnetic environments where multiple devices operate simultaneously in electronic production lines;

　　Field-Grade Durability: The housing is made of wear-resistant and rust-proof aluminum alloy, drop-resistant (no performance degradation after a free drop from a height of 1.5m onto a concrete surface) and vibration-resistant (5~500Hz, 50m/s²), meeting the outdoor field testing needs of communication base stations, radar stations, etc., with a lifespan exceeding 30,000 hours.

　　3. **Multi-instrument Compatibility:** Adapts to all types of RF test equipment.

　　**Customized Interface Design:** Supports dedicated interfaces for various test instruments, including N-type, SMA, 3.5mm, 2.92mm, and 1.85mm (with precision threaded connections, performance unchanged after ≥500 repeated insertions and removals), compatible with mainstream equipment such as spectrum analyzers, signal generators, and vector network analyzers.

　　**Multi-Power Adaptability:** Supports low power (≤1W, suitable for small-signal testing in laboratories), medium power (1-50W, suitable for batch calibration in production lines), and high power (50-200W, suitable for RF power amplifier testing), meeting the power requirements of different testing scenarios.

　　**Calibration Protocol Compatibility:** Supports SCPI (Programmable Instrument Standard Command), enabling integration with Automated Test Systems (ATS) to complete the entire automated testing process from signal transmission to loop transmission to reception calibration, improving testing efficiency (reducing test time per device by 30%).

　　Empowering All-Scenario RF Testing: Key Support from "Data Acquisition" to "Accuracy Certification"

　　R&D Testing: Providing a stable measurement link for the R&D of RF chips, antennas, and other devices, ensuring the repeatability of signal parameters during the R&D process (test data consistency ≥99.9%), accelerating new product iteration;

　　Production Calibration: Adapting to the batch calibration needs of electronic production lines (such as mobile phone RF performance testing, IoT module calibration), ensuring calibration accuracy through low-loss characteristics, and reducing product defect rates (≤0.1%);

　　Field Testing: In field testing at communication base stations, satellite ground stations, etc., resisting complex outdoor electromagnetic interference, ensuring the measurement accuracy of indicators such as signal power and spectral purity, and complying with operator network access testing standards (such as 3GPP TS 38.101).

　　Partnership Guarantee: Test Instrument-Level Supply Chain Services

　　Complete Compliance and Certifications: Products are CE and FCC certified, comply with RoHS 2.0 environmental requirements, and the production line is ISO 9001 quality system certified, supporting mass production (monthly capacity exceeding 300,000 units) with a delivery cycle of ≤2 weeks;

　　Calibration Service Support: Provides NIST (National Institute of Standards and Technology) traceable calibration certificates, assists customers in completing instrument metrology certifications (such as China CNAS and Germany DAkkS certification), and supports annual re-inspection services;

　　Customized Technical Support: For special testing scenarios (such as millimeter-wave radar testing and terahertz device measurement), provides frequency band customization (up to 110GHz) and structural optimization (such as miniaturization and high-power heat dissipation design) solutions, keeps pace with test instrument technology iterations (such as 5G-A and 6G testing equipment), and provides device upgrade services.
