Product Introduction
1. Extreme Noise Control
≤1.0dB noise figure (industry-leading), coupled with a 28±2dB gain LNA, significantly improves weak signal reception sensitivity, making it suitable for use in underground garages and densely populated buildings.
2. Military-Grade Vibration Resistance
Passed a 10-55Hz/1.5mm amplitude vibration test for 2 hours (three times the national standard), meeting the requirements of high-vibration environments such as construction machinery and off-road vehicles.
3. Precise Positioning Performance
▸ Axial ratio ≤ 2dB (Zenith direction)
▸ Frequency band coverage: 1561-1602MHz (GPS L1/Beidou B1 compatible)
▸ 4dBIC gain below ground plane in a 70×70mm footprint
4. Ultra-Low Power Integration
• 3.3V ± 0.3V power supply, power consumption ≤ 24mA (60% reduction compared to previous generation)
• Supports micro interfaces such as IPEX/RF1.37, and features a flush-mount installation thickness of only 6mm
5. Environmental Reliability
-40°C to 85°C wide operating temperature range + 95% humidity tolerance
ROHS certified, lead-free manufacturing process
Application Scenarios
In-Vehicle Smart Terminals: T-BOX, Fleet Management Systems
Construction Machinery Control: Excavator/Crane Positioning and Monitoring
UAV Core Modules: Flight Control, Navigation, and Data Transmission Systems
Industrial IoT: Smart Meters, Asset Tracking Tags
Specialty Equipment: Fire Helmet Positioning, Emergency Rescue Equipment
FAQ
Q: Does it support the Galileo system?
A: It covers the 1561-1602MHz frequency band and is compatible with the Galileo E1 signal (1575.42MHz). The receiver must support decoding.
Q: Is a 70×70mm ground plane mandatory?
A: Yes. The 4dBic gain is based on testing with this size. Insufficient ground plane will result in reduced gain (approximately 1.2dB gain reduction for every 50% reduction in area).
Q: How do I choose the length of the IPEX interface cable?
A: The standard RF1.37 cable (length not specified) is available. Custom lengths of 10cm to 1m are supported. A shielded sleeve is recommended for long-distance transmission.
Q: Can it be used with devices in metal housings?
A: A clearance area of 15mm or greater must be maintained directly above the antenna. The metal housing must be connected to a 70×70mm ground plane.
Q: Can a 3.3V power supply be connected to a 5V power supply?
A: Strictly prohibited! The voltage range is strictly limited to 3.0-3.6V. Overvoltage will damage the LNA chip.
Q: How does the axial ratio change at tilt angles?
A: ≤2dB at zenith, typically ≤3.5dB at 30° elevation (contact technical support for a test report).
Q: What is the LNA gain bandwidth?
A: The bandwidth is not specified, but a V.S.W.R. <2.0 ensures effective operation across the entire 1561-1602MHz band.
