Core application areas are as follows:
1. mmWave test and measurement
• 67 GHz peak power probes, VNA calibration, and spectrum analyzer front-end protection—low standing wave ratio (VSWR 1.15-1.45) ensures test accuracy;
• Extending the dynamic range of power meters to prevent overdriving sensitive components.
2. 5G/6G and commercial communications
• mmWave small base stations and O-RU link leveling—for power balancing in frequency bands such as 28 GHz, 39 GHz, and 60 GHz;
• Signal attenuation for 5G-A prototypes and WiGig (802.11ay) pre-research platforms.
3. Aerospace and Satellites
• Uplink power control for Ka/V band (40-67 GHz) ground stations for low-orbit satellites;
• Intersatellite link payload test bench—thin-film processing and elastic design meet temperature shock and long life requirements.
4. Radar and Electronic Countermeasures
• Power margin testing for mmWave fire control/imaging radar transmitters;
• Electronic countermeasures range—high-power pulse (200 W peak) limiting pre-attenuation to protect the receive link.
5. Research and Education
• University mmWave laboratories and the national 67 GHz metrology standard device—participating in measurement value transfer as a standard attenuator;
• Terahertz front-end R&D (67 GHz is the terahertz transition band) power cascade debugging.
Summary:
The 1.85 mm 67 GHz coaxial attenuator is the standard power regulator for mmWave testing, 5G-A/6G, satellite ground stations, radar ranges, and scientific research metrology. It combines low VSWR, high-power pulse withstand capability, and the long life of a thin-film process, meeting the needs of all scenarios, from desktop testing to field satellite links.
