400-960MHz SMD chip antenna for IoT

Product Introduction

① Ultra-Wide Frequency Band Coverage

Supports an ultra-wide frequency range of 400MHz to 960MHz, perfectly covering mainstream ISM bands such as 433MHz, 868MHz, and 915MHz. A single chip allows for multiple uses, reducing material management costs.

② Miniaturized SMD Design

Measuring only 3.2×1.6×0.4mm, it utilizes a standard SMD package, making it suitable for high-density PCB layouts and saving valuable space in compact devices.

③ Excellent Impedance Matching

50 ohm characteristic impedance and a VSWR <2.0 ensure optimal matching with RF front-end circuits, reducing signal reflections and improving transmission efficiency.

④ High Power Capacity

Supports input power up to 4W, far exceeding the power capacity of conventional SMD antennas and meeting the requirements of high-power transmission applications.

⑤ Industrial-Grade Temperature Adaptability

Operating temperature range: -40°C to +95°C, it meets the rigorous environmental requirements of industrial equipment and ensures stable performance even in extreme temperatures.
