A-INFO Cables (RF/Microwave Coaxial Cable Assemblies) are high-precision, low-loss interconnect solutions engineered by A-INFO Inc. to deliver phase-stable signal transmission across demanding radio frequency, microwave, and millimeter-wave (mmWave) applications.
​Key Technical Specifications & Features ​
ₒ Ultra-Wide Frequency Spectrum: Available in configurations supporting DC up to 18 GHz, 26.5 GHz, 40 GHz, 67 GHz, and 110 GHz. ​
ₒ High Phase & Amplitude Stability: Designed with phase-stable dielectric materials (such as expanded PTFE/ePTFE) to maintain signal integrity during bending, movement, and temperature fluctuations.
ₒ ​Low Insertion Loss & Low VSWR: Features low attenuation and optimized impedance matching (50\ \Omega) with VSWR typically \le 1.20 – 1.35:1, preserving measurement dynamic range.
ₒ Precision Connector Terminations: Terminated with metrology-grade interfaces including SMA, N-Type, 3.5mm, 2.92mm (K), 2.4mm, 1.85mm (V), and 1.0mm connectors.
ₒ ​Mechanical Armor & Strain Relief: Offered in flexible, semi-rigid, and heavy-duty armored (stainless steel braiding/jacket) options to withstand laboratory handling and harsh field conditions. ​Primary Applications
​VNA & RF Test Laboratories: Connecting Vector Network Analyzers, spectrum analyzers, and signal generators during antenna calibration and device characterization. ​Anechoic Chamber Test Interconnects: Linking test antennas (e.g., A-INFO horn antennas) to measurement receiver systems for EMC/EMI compliance testing.
ₒ ​Aerospace, Radar & SatCom: High-frequency interconnects for defense radar modules, satellite ground terminals, and 5G/6G mmWave research setups. ​
