About RFLink
Our Capabilities in RF Design, Manufacturing, and Industry Applications
Dongguan Renfeng Electronic Technology Co., Ltd., operating under the RFLink brand, is a B2B RF antenna manufacturer based in Dongguan, Guangdong, China. Founded in 2012, we focus on the design, development, testing, and production of antennas for wireless communication devices.
We serve global OEM/ODM customers across IoT, smart devices, GNSS positioning, LTE communication, WiFi, LoRa, smart metering, industrial wireless, and communication terminal applications. With RF engineering experience, in-house tooling, injection molding, and scalable production capabilities, RFLink supports customers from product development and prototype evaluation to stable mass production.
Focus on RF Customization: From Concept Development to Mass Production
Founded in 2012, Dongguan Renfeng Electronic Technology Co., Ltd. provides antenna design, development, and manufacturing services under the RFLink brand. We work with B2B customers to address complex RF connectivity challenges and develop custom antenna solutions for wireless devices and communication systems.
Our engineering team consists of experienced RF specialists with an average of more than 13 years of industry experience. We support antenna selection, structural evaluation, rapid prototyping, parameter testing, and device-level optimization.
Depending on the project requirements, engineering evaluations may include VSWR, impedance, gain, antenna efficiency, and radiation performance.
To support projects from development through production, our capabilities are organized across two primary locations:
- R&D and Customization Center in Dongguan: Focused on custom antenna design, prototype development, testing, device integration, and performance optimization.
- Large-Scale Production Base in Jiangxi: Supports scalable manufacturing, quality control, and production coordination after the antenna design and product structure have been verified.

Vertical Integration with In-House Tooling and Injection Molding
Product development speed, structural consistency, and manufacturing stability are critical in wireless communication projects. Unlike traditional assembly-focused suppliers, RFLink combines antenna engineering with in-house tooling and plastic injection molding capabilities to support OEM/ODM customers more efficiently.
Keeping key development and production processes under coordinated management provides several practical advantages:
- Shorter Development Cycles: Closer coordination between antenna engineering, tooling, structural development, and prototype production helps reduce unnecessary communication delays.
- Consistent Quality Control: Improved control over mechanical components, antenna structures, assembly conditions, and production consistency.
- Production Cost Management: Reduced dependence on multiple external suppliers for selected tooling and plastic component processes.
- Design-to-Production Coordination: Engineering changes can be communicated more directly between development, tooling, molding, and manufacturing teams.
These capabilities allow us to support projects requiring custom antenna housings, mounting structures, cable configurations, connectors, branding, and other application-specific modifications.
RF Connectivity Solutions Trusted by Global Industry Leaders
We provide more than standard off-the-shelf antenna products. When an existing antenna cannot meet the available space, frequency, installation, environmental, or performance requirements, our team can evaluate and develop a customized RF solution.
Our antenna development and manufacturing experience covers a broad range of wireless applications:
- IoT and Smart Devices: Antenna solutions for smart home products, industrial IoT devices, monitoring equipment, gateways, sensors, and communication terminals.
- GNSS and Positioning: Antennas for GPS, BeiDou, Galileo, and other positioning applications, based on the device structure and project requirements.
- LTE and Cellular Communication: Internal and external antenna options for cellular terminals, routers, gateways, tracking devices, and industrial equipment.
- WiFi and Bluetooth Devices: Antenna solutions for connected devices requiring compact integration, multiple frequency bands, MIMO configurations, or controlled coverage.
- LoRa and Sub-1 GHz Applications: Antennas for smart metering, agricultural monitoring, remote control, industrial sensing, and long-range, low-power wireless networks.
- UAV and Drone Communication: Lightweight antenna solutions for telemetry, positioning, control, and wireless video transmission applications.
- Communication Infrastructure: Fiberglass, sector, directional, ceiling-mounted, and parabolic antenna options for different coverage, mounting, and network requirements.
Antenna performance depends on more than the antenna specification alone. The enclosure, ground plane, battery, display, cable, connector, installation position, and surrounding materials can all influence RF performance.
For this reason, we encourage customers to provide device drawings, structural information, frequency requirements, installation conditions, and target performance details during the evaluation stage.
Our commitment to agility, engineering precision, and manufacturing quality has earned the trust of leading global telecommunications brands, including strategic partnerships with Huawei and ZTE.
