Core Product Features: 490MHz Frequency Optimization, Orange-Yellow Marking for Easy Production Line Integration

1. Electrical Characteristics: Precise Frequency + Stable Transmission

• 490±5MHz Dedicated Coverage: Operating frequency is precisely locked at 490±5MHz, deeply compatible with LoRaWAN (Low Power Wide Area Network) communication standards, serving as a core component for industrial IoT and smart monitoring terminals. This frequency band belongs to the LoRaWAN (CN470) downlink channel cluster (500.3~509.7MHz) in China, enabling seamless access to enterprise-built IoT private networks without relying on operator-licensed spectra.
• Low VSWR + Moderate Gain: Voltage Standing Wave Ratio (V.S.W.R) is <2.5, combined with 50Ω standard input impedance, effectively reducing signal reflection and energy loss. The 1dBi gain adopts vertical polarization design, supporting 360° omnidirectional radiation. In scenarios like LoRa node networking and industrial sensor data backhaul, it ensures uniform signal coverage and stable reception, balancing transmission distance and power consumption, which is especially suitable for battery-powered long-endurance devices.
• High Power Stable Capacity: With a power capacity of 50W, it supports stable operation of industrial-grade wireless data transmission modules and high-power LoRa gateways. Even in scenarios with concurrent data from multiple nodes (e.g., dozens of environmental sensors in a park transmitting simultaneously), it avoids signal interruption caused by power overload, ensuring communication continuity.

2. Mechanical Characteristics: SMD Mounting + Orange-Yellow Marking, Maximizing Mass Production Efficiency

• Small-Size SMD Integration: Overall dimension is 15mm×3.2mm×1.6mm, weight is only 0.2g. Adopting SMD (Surface Mount Device) technology, it can be directly welded in batches via SMT production lines and seamlessly integrated with device PCB boards, perfectly adapting to the "miniaturization and high integration" design trend of terminal devices, such as micro LoRa nodes and industrial sensing modules.
• Orange-Yellow PCB Material for Easy Identification: The main body is made of orange-yellow PCB material, which has extremely high visual recognition in production lines, facilitating quick identification and welding by automated equipment and reducing production misjudgment rates. The PCB material also has excellent electrical performance and structural stability, not easy to fall off after welding, and is compatible with large-scale automated production processes, greatly improving mass production efficiency and yield.
• No Additional Cables/Connectors: Directly integrated on the device PCB board, no external cables or connectors are required, reducing component space occupation and signal transmission loss, simplifying the internal wiring design of the terminal, and making the product more concise and reliable.

3. Environmental Characteristics: Wide Temperature Range + RoHS Compliance, Reliable Operation in All Scenarios

• Ultra-Wide Temperature Adaptation: Both operating and storage temperature ranges are -45~+85℃, enabling stable operation in extreme scenarios such as extremely cold winters in northern regions (-40℃), industrial high-temperature workshops (+80℃), and outdoor exposure environments (+70℃), without additional temperature control measures. It is suitable for multi-scenario deployment such as LoRa IoT outdoor nodes, industrial automation equipment, and polar scientific research sensing terminals.
• RoHS Compliance for Eco-Friendliness: Strictly RoHS compliant, free of harmful substances such as lead and cadmium. It can be safely used in consumer-grade LoRa smart devices (e.g., smart home sensors) and industrial-grade wireless terminals, meeting the environmental and compliance requirements of the global market and eliminating compliance barriers in international trade.

Multi-Industry Application Scenarios: Covering Core Needs of 490MHz Wireless for Intelligent Upgrades in All Fields

1. LoRaWAN IoT: Smart Monitoring & Distributed Networking. Compatible with LoRaWAN monitoring nodes (e.g., smart water meters, environmental quality sensors), SMD mounting makes the nodes more compact, and 1dBi omnidirectional gain ensures stable data backhaul in multi-node networking within cities and parks. The wide temperature range supports outdoor nodes operating long-term in environments from -30℃ to +60℃, facilitating large-scale deployment of LoRa IoT in smart cities for functions like remote device monitoring and real-time data upload.
2. Industrial IoT: Equipment Status & Data Collection. Matched with 490MHz industrial sensors (e.g., equipment vibration sensors, temperature and humidity sensors), it occupies no space after being embedded into the device PCB board (15mm size). Vertical polarization and omnidirectional radiation enable stable signal backhaul to the gateway in complex factory layouts, supporting predictive maintenance of equipment and real-time monitoring of production environments, especially suitable for industrial workshops with high dust, high and low temperatures.

In smart security systems, it serves as a 490MHz sensing antenna (e.g., perimeter infrared sensors, vibration intrusion detectors), and SMD mounting can be hidden and integrated at the edge of devices. The 490MHz frequency band avoids Wi-Fi interference, and 1dBi gain ensures stable upload of sensing data (e.g., intrusion alarms, abnormal vibrations) to the central control gateway, enhancing the response speed and reliability of security systems.
4. Outdoor Asset Tracking: Equipment Positioning & Status Management. Matched with 490MHz outdoor asset tracking terminals (e.g., logistics container tags, engineering machinery positioning modules), the wide temperature range adapts to extreme environments such as mountains (-20℃) and deserts (+60℃). Omnidirectional radiation ensures stable communication between the terminal and the gateway in the wilderness, providing reliable data support for asset positioning and equipment status management.
