Abracon ACPI GNSS 90° Hybrid 3dB Couplers
Abracon ACPI GNSS 90° Hybrid 3dB Couplers combine two orthogonal antenna modes with equal amplitude and 90-degree phase shift, forming clean circular polarization. The ACPI-WB-0001 and ACPI-WB-0002 couplers support L1/L2/L6 and L1/L2/L5/L6 bands, respectively, across 1.15GHz to 1.70GHz frequency ranges. The ACPI hybrid 3dB couplers deliver a maximum of 0.3dB insertion loss, >20dB high isolation, and ±0.35dB tight amplitude balance to enable excellent axial-ratio performance across wide GNSS bands. These couplers handle up to 30W of average input power and operate over a temperature range of -55°C to 95°C. The ACPI hybrid 3dB couplers preserve weak GNSS signals and minimize self-interference and cross-coupling. These couplers improve positioning accuracy, fix reliability, and handle high RF power margins efficiently. Typical applications include high-precision positioning systems, asset tracking and telematics, UAVs and drones, intelligent transportation, and precision agriculture.
