BW3GRSNX32-5W9弹簧天线产品概述

一、产品定位与核心场景

BW3GRSNX32-5W9是BAT WIRELESS推出的双频段小型化弹簧天线,专为空间受限的无线通信设备设计,聚焦中功率、宽覆盖的物联网与移动通信场景。其核心覆盖892MHz(GSM/窄带物联网)与1.85GHz(3G/4G通用频段),可满足智能终端、工业传感器、车载通信等多场景的信号收发需求,无需额外配置多天线,有效降低设备集成成本。

典型应用包括:

  • 智能抄表(水/电/气表)的无线数据传输;
  • 手持POS机、快递终端的移动通信;
  • 工业物联网传感器(如环境监测、设备状态采集)的远程回传;
  • 车载T-BOX、GPS定位终端的信号增强。

二、核心技术参数解析

该天线的参数设计针对小型化设备的信号需求做了优化,关键指标如下:

1. 频段与带宽

  • 双中心频率:892MHz(覆盖824960MHz,含GSM 850/900、NB-IoT B8)、1.85GHz(覆盖1.711.99GHz,含WCDMA 1800、LTE B3/B8);
  • 带宽:136MHz(892MHz频段)、280MHz(1.85GHz频段),宽带宽设计可兼容多运营商网络,避免频段漂移导致的信号衰减。

2. 性能指标

  • 增益:4dBi(比普通内置天线提升30%以上信号强度),在室内或弱信号区域仍能保证稳定传输;
  • 阻抗:50Ω(匹配主流射频模块接口,无需额外阻抗匹配电路);
  • 功率容量:50W,支持中功率发射场景(如工业无线数传);
  • 驻波比(VSWR):≤2,信号反射损耗低,传输效率达90%以上。

3. 尺寸规格

  • 直径φ5mm,长度32mm,超小型化设计,可嵌入10mm×10mm以内的设备空间,不影响终端外观。

三、结构设计与性能优势

BW3GRSNX32-5W9采用弹簧天线结构,兼具柔韧性与信号稳定性,核心优势如下:

1. 抗弯折与安装灵活性

弹簧结构可承受多次弯折(弯折角度≤120°),适合设备内部空间狭窄、需调整天线角度的场景(如手持终端的握把内部);安装方式兼容贴装、嵌入式或螺丝固定,适配不同设备结构。

2. 双频段共体设计

无需额外增加天线数量即可覆盖两大主流频段,减少设备内部射频走线复杂度,降低电磁干扰风险,提升整体通信可靠性。

3. 信号覆盖增强

4dBi增益结合宽带宽,可将信号覆盖范围提升至普通天线的1.5倍,尤其在地下停车场、高楼密集区等弱信号区域,有效减少丢包率与连接中断。

四、环境适应性与可靠性

针对工业与户外场景的严苛需求,该天线具备以下环境特性:

  • 宽温工作范围:-40℃~+80℃,可稳定运行于低温(如北方冬季户外)、高温(如南方夏季设备箱内)环境;
  • 抗震动性能:弹簧结构自带缓冲,可承受10g(10~2000Hz)的震动测试,适合车载、无人机等移动设备;
  • 耐候性:表面采用抗腐蚀涂层,可防止户外环境下的盐雾、潮湿侵蚀(满足盐雾测试100小时要求)。

五、集成与使用注意事项

  1. 安装时尽量避免天线靠近金属外壳(距离≥5mm),防止信号屏蔽;
  2. 射频接口建议采用IPEX或SMA接头,确保50Ω阻抗匹配;
  3. 工作功率请勿超过50W,避免天线发热影响性能;
  4. 户外使用时建议搭配防水外壳,进一步提升耐候性。

总结:BW3GRSNX32-5W9以“小型化、双频段、高增益”为核心亮点,兼顾性能与成本,是物联网终端、工业通信设备等场景的高性价比天线解决方案。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

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
