BW433FNX45-17B1 433MHz 射频天线产品概述

一、产品定位与典型应用场景

BW433FNX45-17B1是蝙蝠无线(BAT WIRELESS) 针对433MHz ISM频段打造的紧凑型全向天线,核心定位为中短距离无线通信的小型化集成方案,适配工业物联网、远程抄表、智能家居等场景的射频终端。

其典型应用包括:

  • 工业物联网(IIoT):车间温湿度传感器、设备状态监测节点;
  • 远程抄表:智能电表/水表/燃气表的无线通信模块;
  • 智能家居:遥控主机、门窗传感器、智能门锁;
  • 农业物联网:田间土壤湿度/温度传感器、无人机数据传输终端。

该天线解决了传统天线体积大、安装不便的痛点,可直接嵌入小型设备内部,兼顾信号稳定性与设备集成性。

二、核心技术参数深度解析

BW433FNX45-17B1的参数经过针对性调校,匹配433MHz频段的通信需求:

1. 频率与增益

  • 中心频率:433MHz(覆盖430-434MHz ISM频段),避免频段偏移导致的信号衰减;
  • 增益:3dBi全向增益,平衡信号强度与功耗——城市环境下覆盖300-800米,开阔地可达1.5公里以上,无需额外高增益天线即可满足多数场景需求。

2. 阻抗与驻波比

  • 阻抗:50Ω标准射频阻抗,与CC1101、SX1278等主流射频模块完美匹配;
  • 驻波比(VSWR):≤1.8,信号反射损耗控制在合理范围(驻波比越低,信号效率越高),有效降低通信误码率。

3. 功率与尺寸

  • 最大输入功率:50W,满足高功率发射场景(如抄表集中器),避免功率过载损坏;
  • 尺寸:45mm(长)×17mm(宽),紧凑片状设计,重量轻(无具体参数但推测≤5g),便于嵌入小型终端。

三、结构与接口设计

1. 接口特性

采用IPEX(U.FL)接口,这是射频领域广泛应用的小型化接口:

  • 体积小:仅3-5mm大小,适配设备内部布线;
  • 易连接:直接焊接到射频模块的IPEX座,无需复杂同轴接头;
  • 抗振性强:连接牢固,适合工业/户外环境的长期振动场景。

2. 安装灵活性

天线为片状结构,可通过双面胶固定在设备内部塑料壳上,或直接焊接到主板指定位置,无需额外支架,安装方式灵活且不占用额外空间。

四、环境适应性与可靠性

BW433FNX45-17B1针对工业级场景优化了环境耐受性:

  • 宽温工作:-40℃~+80℃,覆盖我国南北极端气候(北方冬季低温、南方夏季高温),以及工业现场的温差变化;
  • 品牌保障:蝙蝠无线专注射频天线研发10余年,产品通过振动测试(10-2000Hz)、高低温循环测试(-40℃→+80℃,50循环),长期使用故障率低。

五、使用注意事项

  1. 阻抗匹配:必须连接50Ω射频模块,避免阻抗不匹配导致信号衰减;
  2. 安装避障:远离金属物体(如设备内部金属支架、电池),否则会干扰天线辐射;
  3. 功率限制:输入功率不超过50W,避免过载损坏;
  4. 焊接工艺:IPEX接口焊接温度控制在260℃以内,建议用恒温烙铁或热风枪,避免过热损坏接口。

综上,BW433FNX45-17B1是一款高性价比、小型化、工业级的433MHz天线,适合对体积、可靠性有要求的无线通信终端,是物联网场景中射频天线的优选方案。

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
