Product Introduction
1. Precise Frequency Lock
Center frequency 1575.42MHz ±3.0MHz (GPS L1 standard frequency), frequency temperature coefficient ±20ppm/°C, frequency deviation ≤0.05MHz in extreme temperature environments, ensuring signal stability.
2. Low-loss, high-efficiency transmission
▸ Return loss ≥15dB @ F0, VSWR ≤1.5
▸ 10dB bandwidth ≥6.5MHz, suitable for signal capture in high-speed mobile scenarios
3. Compact and highly anti-interference design
• Ultra-small 20×20mm ground plane saves PCB space
• Right-hand circular polarization (RHCP) suppresses multipath interference, ensuring more reliable positioning in urban environments
4. Guaranteed performance over a wide temperature range
-40°C to +85°C operating temperature range, measured in real-world conditions Gain reduction at 10° elevation angle ≤3.0dB (comparable products average 4dB), 30% faster startup in low temperatures.
5. Plug-and-play integration
50Ω standard impedance matching, compatible with FR4/ceramic substrates, no complex tuning required.
Application Scenarios
In-vehicle navigation: Aftermarket vehicle GPS terminals, OBD fault diagnostic tools
IoT devices: Shared bicycle positioning locks, logistics trackers
Portable terminals: Handheld surveying instruments, outdoor emergency positioning equipment
Industrial control: AGV navigation modules, smart meter timing systems
Consumer electronics: Drone image transmission modules, activity recorders
FAQ
Q: Does it support GLONASS or BeiDou?
A: It is optimized for GPS L1 (1575.42MHz) and is not compatible with other satellite system frequency bands.
Q: Why is the axial ratio parameter not listed?
A: It has been verified that this is an omission in the documentation. The measured axial ratio is ≤5dB (@1575MHz). Please contact customer service to obtain a test report.
Q: Is 2.0dBi gain sufficient?
A: Designed for short-range reception (≤10km), it can be increased to 28dBi with an external LNA, making it suitable for consumer devices.
Q: Is impedance matching required?
A: 50Ω standard impedance allows direct connection to RF modules (such as the ublox NEO series) without the need for additional matching components.
Q: What is its waterproof performance?
A: It does not have an IP rating. It is recommended for indoor use or installation in a protective enclosure. Custom conformal coating versions are available.
