Product Introduction
1. Industrial-Grade Ultra-High Gain
The built-in LNA amplifier provides 28±2dBi gain, far exceeding conventional antennas (15-20dBi), significantly enhancing satellite signal acquisition capabilities.
2. Precision Frequency Stability
The center frequency is 1575.42±0.5MHz (GPS L1 band), with a VSWR ≤1.5, ensuring a perfect match with the navigation chip.
3. Harsh Environmental Adaptability
A wide operating temperature range of -40°C to 85°C and 75% humidity tolerance, compliant with ROHS environmental standards, making it suitable for in-vehicle and outdoor industrial equipment.
4. Ultra-Low Noise
A 1.1dB noise figure (industry average >2dB) reduces signal distortion and improves positioning accuracy by 30% in weak signal areas.
5. Flexible Wide Voltage Power Supply
An ultra-wide 2.2-5V DC input voltage draws only 10mA, making it compatible with various IoT device power systems.
Application Scenarios
Heavy Machinery Positioning: 50W high power tolerance to handle engine vibration interference from excavators and agricultural machinery.
Cold Chain Logistics Monitoring: Stable operation at -40°C, ensuring real-time tracking of refrigerated trucks.
Base Station Synchronization Device: 1575.42MHz precise frequency to meet the time synchronization requirements of communication base stations.
Agricultural Autonomous Driving: RHCP polarization for multipath mitigation and precise navigation in complex farmland terrain.
Solar Tracker: 2.2V low-voltage startup to accommodate low-power operation of photovoltaic equipment.
FAQ
Q: Is the IPEX connector compatible with UFL?
A: Fully compatible! IPEX is an upgraded version of UFL, and the physical specifications of the interface are the same.
Q: Can the 25x25x7mm size be embedded in a drone?
A: Recommended for medium-sized industrial drones (≥30cm wheelbase). For micro drones, a smaller size is recommended.
Q: Is an external matching circuit required?
A: No! The 50Ω nominal impedance is directly compatible with mainstream RF modules, and the VSWR ≤ 1.5 is optimized for matching.
Q: Does the 28dBi gain require an external power supply?
A: Yes! The internal LNA requires a 2.2-5V power supply.
Q: Does the 75% humidity limit affect coastal use?
A: It meets IP54 protection (depending on the structural design), but it is recommended to install a moisture-proof seal to protect against salt spray environments.
Q: Can it receive GLONASS signals?
A: It is designed specifically for the GPS L1 band (1575.42MHz). GLONASS requires a 1602MHz band antenna.
Q: Can the 100mm cable length be customized?
A: Yes! The RG1.13 coaxial cable can be customized to 150/200/300mm.
