BW433SNX21-5W2是BAT WIRELESS(蝙蝠无线) 针对433MHz ISM频段推出的小型化弹簧天线,专为空间受限的射频终端设计。其核心设计亮点在于螺旋弹簧结构:相比传统鞭状天线,体积大幅缩小的同时,保留了可靠的射频辐射性能,可适配传感器节点、遥控器等紧凑设备的集成需求。
型号命名逻辑清晰:
该天线的性能参数精准匹配433MHz频段的工业/物联网应用需求,核心指标如下:
工作于433MHz ISM免授权频段,无需额外频谱申请,可直接部署于工业控制、物联网等场景;中心频率精度符合射频系统匹配要求,与主流无线模块(如CC1101、SX1278、A7105等)直接兼容。
增益达2dBi,相比普通弹簧天线(通常1dBi左右)提升约30%的有效辐射功率,可扩展信号覆盖范围(中短距离场景:室内100-300米,室外300-500米),减少终端与基站间的信号衰减。
阻抗匹配为50Ω(射频系统标准阻抗),无需额外阻抗匹配电路;驻波比(VSWR)≤1.8,远低于“VSWR≤2”的通用要求,信号反射损耗<1dB,传输效率显著提升,可降低系统功耗与信号误码率。
最大承受功率50W,高于同类弹簧天线(常规10-30W),可适配大功率发射模块,避免天线因过功率损坏,延长产品使用寿命。
直径仅5mm、长度21mm,属于“指尖级”天线,可轻松集成于传感器节点、遥控器、小型射频终端等空间受限设备中,无需额外占用安装空间。
工作温度覆盖**-40℃~+80℃**,满足极端环境需求:
采用裸露弹簧结构(无特殊封装),可通过焊接、螺纹固定或卡扣式安装适配不同终端,安装流程简单,降低终端集成成本。
结合小尺寸、宽温适应性与433MHz频段特性,该天线广泛应用于以下场景:
BAT WIRELESS是国内专注射频天线研发的专业厂商,拥有10+年天线设计经验,产品覆盖ISM、蓝牙、WiFi等多频段。BW433SNX21-5W2经过严格可靠性测试:
确保在复杂环境下长期稳定运行,同时提供定制化服务(如频率微调、增益调整),满足客户个性化需求。
该产品以“小体积、高性能、宽适应”为核心优势,是433MHz频段无线终端的高性价比天线选型。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
