BW2.4SNX12-3Z9 2.4GHz弹簧天线产品概述

一、产品定位与核心应用

BW2.4SNX12-3Z9是BAT WIRELESS推出的2.4GHz ISM频段小型化弹簧天线,专为紧凑型无线设备设计,核心覆盖蓝牙(BLE)、Wi-Fi 2.4G、ZigBee、无线传感器网络等主流2.4G协议应用,可满足工业监测、智能家居、可穿戴设备、物联网终端等场景对小体积、高可靠性天线的需求。

二、关键性能参数解析

该天线的性能参数针对2.4G频段应用做了针对性优化,核心参数及实际意义如下:

  • 中心频率2.45GHz:精准匹配2.4GHz ISM频段的主流应用中心(蓝牙、Wi-Fi 2.4G、ZigBee等均以2.45GHz为核心工作频率),无需额外调谐即可实现高效谐振;
  • 带宽100MHz(2.4~2.5GHz):覆盖2.4G频段全范围,支持多协议同时工作(如蓝牙+Wi-Fi并行),避免频段冲突;
  • 增益2dBi:在φ3mm×12mm的超小体积下实现合理增益,兼顾信号覆盖范围(10~50米短/中距离)与设备小型化需求;
  • 阻抗50Ω:匹配射频电路通用阻抗标准,减少信号反射损耗,提升传输效率;
  • 最大输入功率50W:支持较高功率发射,可满足需要更远传输距离的工业/户外场景(如小型无线网关);
  • 驻波比(VSWR)≤1.8:远低于2的行业阈值,反射损耗小(约-10dB以上),确保信号能量高效辐射;
  • 工作温度-40℃~+80℃:宽温范围覆盖工业级环境(如低温户外、高温车间),适应恶劣工况;
  • 尺寸φ3mm×12mm:直径仅3mm(约铅笔芯粗细)、长度12mm,可嵌入式安装于设备内部(如智能手环、传感器节点),不影响设备外观与便携性。

三、结构设计与工艺特点

BW2.4SNX12-3Z9采用螺旋弹簧式结构,通过增加有效辐射长度实现小体积下的目标频段谐振:

  • 弹簧材质选用高导电率铜合金,确保低损耗;
  • 表面处理采用抗氧化涂层,提升长期可靠性(避免户外/工业环境下氧化);
  • BAT WIRELESS的天线设计经验保证批量生产一致性(驻波比、增益偏差控制在±5%内),适合规模化设备应用。

四、典型应用场景

  1. 工业无线传感器网络:温度、湿度、压力、液位监测节点(适应-40~+80℃宽温);
  2. 智能家居终端:智能开关、门窗传感器、小型网关(兼容蓝牙/ZigBee);
  3. 可穿戴设备:智能手环、运动手表、无线耳机(小尺寸适配手腕/耳挂空间);
  4. 物联网低功耗终端:智能电表、燃气表、农业土壤监测节点(长寿命、小体积);
  5. 户外便携设备:手持终端、小型无人机、应急通信模块(宽温+抗干扰)。

五、选型与安装注意事项

5.1 选型优势

  • 超小尺寸适配紧凑型设备设计,无需额外预留大空间;
  • 宽温范围满足工业级应用,无需额外防护即可适应极端温度;
  • 低驻波比+50Ω阻抗保证信号效率,降低系统功耗;
  • 多协议兼容降低系统设计复杂度,减少天线选型成本。

5.2 安装注意事项

  • 避免靠近金属部件:金属会屏蔽天线信号,建议安装位置距离设备外壳、电池等金属≥10mm;
  • 匹配射频接口:需配合SMA、IPEX等50Ω射频连接器使用,避免阻抗不匹配导致信号损耗;
  • 功率限制:输入功率不超过50W,避免天线过热损坏;
  • 安装方向:弹簧天线为全向辐射,但尽量保持垂直安装(提升水平方向覆盖均匀性)。

总结

BW2.4SNX12-3Z9作为一款小型化、高可靠的2.4GHz弹簧天线,凭借超小尺寸、宽温性能、多协议兼容等优势,成为工业监测、智能家居、可穿戴等场景的理想选择。BAT WIRELESS的专业设计与工艺保障,使其在批量应用中具备稳定的性能表现,可有效降低无线设备的天线设计难度与成本。

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
