About Products
Core Product Features: High Gain + Ultra-Mini, Balancing Performance and Extreme Integration
1. Electrical Characteristics: 2.4G Full-Band Optimization for Efficient and Stable Transmission
- Precise Full-Band Coverage: The operating frequency range is locked at 2400-2500MHz, perfectly matching mainstream 2.4GHz wireless technologies such as Wi-Fi (2.4G), Bluetooth, and ZigBee. There is no need to replace antennas due to protocol or device differences, making it a core communication component for "2.4G ecosystem" products such as IoT, smart homes, and micro electronic devices.
- Low VSWR + High Gain Empowerment: Voltage Standing Wave Ratio (V.S.W.R) is <2, combined with 50Ω standard input impedance, which minimizes signal reflection and energy loss to the greatest extent. The 3.85dBi gain adopts a vertical polarization design, enabling more balanced vertical signal penetration and coverage in multi-device dense indoor environments (such as smart home scenarios) or complex outdoor scenarios, significantly improving signal reception sensitivity and making data transmission more stable and longer-range.
- High Power Stable Capacity: With a power capacity of 50W, it can support the stable operation of industrial-grade 2.4G wireless data transmission modules, high-bandwidth Wi-Fi terminals and other devices. Even when facing concurrent transmission of multiple devices (such as multiple Wi-Fi devices connected to the network simultaneously in an office, or batch data backhaul of multiple sensors in a factory), it can avoid performance degradation caused by power overload and ensure communication continuity.
2. Mechanical Characteristics: Ultra-Mini SMD Design for Extreme Integration and Easy Mass Production
- Micron-Level Ultra-Small Size: The overall size is only 3.35mm×1.75mm×1.2mm (about the size of a small grain of rice), and the weight is only 0.2g (close to the weight of a hair). It can be easily integrated into ultra-small devices such as smart watches, micro sensors, TWS earphones, and industrial micro modules, perfectly adapting to the "extreme miniaturization" design trend of consumer electronics and IoT terminals, and solving the industry pain point of "communication antennas occupying space in small devices".
- SMD Mounting + PCB Material: Adopting SMD (Surface Mount Device) technology, it can be directly welded in batches through SMT (Surface Mount Technology) production lines and seamlessly integrated with device PCB boards. The main body is made of PCB material, which has excellent electrical performance and structural stability, is not easy to fall off after welding, and is compatible with automated production processes, greatly improving mass production efficiency and yield, and reducing the cost and difficulty of large-scale production.
- No Additional Cables/Connectors: There is no need for external cables or connectors, and it is directly integrated on the device PCB board, which not only reduces component space occupation and signal transmission loss, but also simplifies the internal wiring design of the device, making terminal products more concise and reliable.
3. Environmental Characteristics: Wide Temperature + Environmental Compliance for Reliable Operation in All Scenarios
- Ultra-Wide Temperature Adaptation: Both operating and storage temperature ranges reach -45~+85℃, enabling stable operation in extreme environments such as extremely cold winters in northern regions (-40℃), hot summers in southern regions (+70℃), and industrial high-temperature workshops (+80℃), without additional temperature control measures, and suitable for multi-scenario deployment such as outdoor environmental monitoring, industrial automation, and polar scientific research.
- RoHS Compliance for Eco-Friendliness: Strictly RoHS compliant, free of harmful substances such as lead and cadmium. It can be safely used in children's wearable devices, medical monitoring terminals, as well as consumer electronics and industrial products, meeting the environmental and compliance requirements of the global market and eliminating compliance barriers in international trade.
Core Advantages: Focus on "High Gain, Ultra-Mini, Strong Adaptability" to Empower Miniaturized Smart Devices
- "High Gain + Low VSWR" Better Transmission: 3.85dBi high gain improves signal coverage and reception capability, and VSWR <2 reduces signal waste. In 2.4G frequency band multi-interference environments (such as coexistence of multiple Bluetooth devices at home, dense Wi-Fi scenarios in offices), it can still ensure stable and high-speed transmission of data (such as health data of wearable devices, monitoring data of sensors), improving the communication reliability of devices.
- "Ultra-Small Size + SMD Technology" Full Integration: The extreme size of 3.35×1.75×1.2mm + SMD mounting technology can be seamlessly embedded into products with extremely sensitive space such as smart watches and micro sensors, helping terminals achieve design breakthroughs of "smaller, lighter, and more beautiful".
- "Wide Temperature Range + RoHS Compliance" Wide Scene Coverage: The -45~+85℃ wide temperature range adapts to most climate and industrial scenarios around the world, and can work stably from desert monitoring terminals to polar scientific research equipment; RoHS compliance allows the product to enter fields with high environmental requirements such as medical and consumer electronics, expanding the application boundary.
Multi-Industry Application Scenarios: Covering Core Needs of 2.4G Wireless to Empower Intelligent Upgrades in All Fields
- Consumer Electronics: Smart Wearables & Micro DevicesCompatible with smart watches, TWS true wireless earphones, micro action cameras and other devices. The ultra-mini size can be hidden and integrated inside the watch case or earphone cavity. The 2.4G frequency band supports Bluetooth calls and Wi-Fi networking (such as watch synchronizing mobile phone data, low-latency audio transmission of earphones), and high gain ensures that the signal is not interrupted during exercise (such as running, mountain climbing), making the communication of wearable devices more stable and the battery life longer.
- Smart Home: Sensing & Control TerminalsMatched with 2.4G smart home sensors (such as temperature and humidity sensors, human infrared sensors), smart switches and other terminals, the SMD chip is directly welded on the device PCB, saving internal space. Vertical polarization and omnidirectional radiation enable signal coverage in every corner of the home, ensuring real-time upload of sensor data (such as temperature and humidity data transmitted from living room sensors to the gateway) and accurate delivery of switch commands (such as remote control of bedroom lights via mobile phones), improving the intelligence experience and response speed of homes.
- Industrial IoT: Micro Monitoring & Data Transmission ModulesUsed in industrial micro vibration sensors, temperature and humidity monitoring nodes and other devices, PCB material resists electromagnetic interference in industrial environments, and the -45~+85℃ wide temperature adapts to temperature changes in workshops. 50W power supports high-bandwidth data transmission (such as real-time backhaul of equipment vibration data), and SMD technology is compatible with batch production in industrial automated production lines, helping factories achieve equipment condition monitoring and predictive maintenance, and reducing downtime losses.
- Medical Health: Portable Monitoring DevicesCompatible with portable ECG monitors, blood glucose detectors and other medical terminals, the ultra-small size can be embedded in the device case without affecting portability. RoHS compliance ensures safety in contact with the human body, and the 2.4G frequency band supports the device to transmit health data (such as ECG waveforms, blood glucose values) to mobile phones or medical cloud platforms. High gain enables data transmission without delay, assisting doctors in real-time diagnosis and telemedicine.
- Outdoor IoT: Environmental & Security SensingMatched with outdoor micro environmental monitoring sensors (such as atmospheric pressure sensors, light sensors), security infrared detectors, the wide temperature range adapts to extreme outdoor weather (such as -30℃ in mountains, +60℃ in deserts); omnidirectional radiation ensures that sensors can stably transmit environmental data back to the 2.4G gateway in the wilderness, providing reliable data support for meteorological research, scenic spot security, and agricultural monitoring.
