• Connection Solution: IPEX-1 connector (customizable), RG1.13 cable (customizable), cable length 120 mm (customizable), providing flexible adaptation solutions for different devices.
• Mounting Method: Press-fit, the installation process is efficient and convenient, reducing production line labor costs.
• Appearance and Material: Silver-white ceramic material, durable and with industrial design sense, weighing only 5.8 g, and the lightweight attribute has negligible impact on the overall weight of the device.
• Environmental Characteristics
• Environmental Compliance: RoHS compliant, meeting global environmental standards and applicable to multiple fields such as consumer electronics and industrial equipment.
• Temperature Adaptability: Operating temperature -45~+85℃, storage temperature -45~+85℃, can operate stably in extreme environments such as extreme cold (e.g., polar exploration) and high temperature (e.g., industrial production lines).

Advantages

• Stable Signal Reception: The combination of RHCP and high-gain LNA can still stably capture satellite signals in weak signal scenarios such as urban canyons and tunnels, ensuring positioning continuity.
• Easy Integration: 50Ω standard impedance and customizable connection solutions can seamlessly interface with various navigation modules and communication devices, shortening product development cycles.
• Robust Quality: Ceramic material is wear-resistant, wide temperature range design resists environmental interference, RoHS compliance adapts to global market access, and long-term use reliability is strong.
• Flexible Design: Ultra-small size and lightweight body reserve more creative space for the structural design of smart wearables, micro-drones and other devices.

Application Scenarios

• Vehicle Navigation: Integrated into in-vehicle central control navigation systems, it can still provide precise positioning in urban high-rise areas, underground parking lots and other scenarios, assisting in intelligent driving and path planning.
• Handheld Outdoor Devices: Such as outdoor adventure GPS handhelds, the lightweight and low-power characteristics make it a "positioning tool" for hiking and mountaineering enthusiasts.
• Industrial Internet of Things (IIoT): In industrial asset tracking (such as warehouse logistics labels) and intelligent sensors, the wide temperature range and high reliability can adapt to complex environments such as high temperature in factories and severe cold outdoors, realizing the whole-life cycle precise management of assets.
• Smart Wearables: Embedded in the navigation module of smartwatches and sports bracelets, the small size design does not affect the portability of the device, providing users with real-time location, movement trajectory and other services.
• Drone Systems: In the flight control module of consumer or industrial drones, the high-gain antenna ensures precise navigation over long distances and complex terrains, assisting in the smooth development of aerial photography, mapping and other tasks.
