BW258PNX40-8B1 无线天线产品概述

BW258PNX40-8B1是BAT WIRELESS(蝙蝠无线)推出的一款双频小型化射频天线,针对工业级无线通信、物联网终端及短距离高功率传输场景优化设计,兼顾多频段兼容、功率耐受与环境适应性,为各类无线设备提供稳定可靠的信号覆盖方案。

一、产品定位与核心价值

该天线聚焦双频(2.4GHz/5.8GHz)覆盖与高功率耐受两大核心需求,适配主流ISM频段(工业、科学、医疗频段)的无线协议,包括Wi-Fi(2.4G/5G)、蓝牙、无线传感网络(WSN)、射频识别(RFID)等。其核心价值体现在:

  • 单天线实现双频信号收发,降低系统集成复杂度;
  • 50W功率耐受能力满足工业级大功率通信需求;
  • 宽温范围与小型化设计适配极端环境与紧凑设备;
  • 低驻波比保障信号传输效率,减少反射损耗。

二、关键技术参数详解

1. 双频覆盖特性

中心频率覆盖2.4GHz(ISM主频段)与5.8GHz(5G Wi-Fi/ISM扩展频段),可同时兼容新旧无线协议:

  • 2.4GHz频段:覆盖Wi-Fi 4/5、蓝牙4.2/5.0、ZigBee等低功耗/中距离协议;
  • 5.8GHz频段:支持Wi-Fi 5/6高带宽通信,抗干扰能力更强(避开2.4GHz频段拥挤环境)。

2. 增益与信号覆盖

增益为4dBi,属于中增益天线范畴:

  • 平衡信号覆盖距离与体积(40mm×8mm小型化),适合10-50米范围内的稳定通信;
  • 避免高增益带来的波束窄、易遮挡问题,适配复杂环境下的信号穿透需求。

3. 功率与阻抗匹配

  • 功率耐受:50W:支持工业级大功率射频模块(如无线数据传输、远程控制模块),避免高功率下天线损坏;
  • 阻抗:50Ω:与绝大多数射频电路、模块的标准阻抗匹配,无需额外阻抗转换,简化系统设计。

4. 驻波比与信号质量

驻波比(VSWR)≤1.8:

  • 驻波比越低,信号反射损耗越小,传输效率越高;
  • 1.8的驻波比满足工业级通信的信号稳定性要求,避免因反射导致的信号衰减或模块误判。

三、应用场景适配

BW258PNX40-8B1的参数特性使其适配多类场景:

1. 工业无线传感网络

  • 宽温范围(-40℃~+80℃)适配户外工业现场(如矿山、油田、工厂车间);
  • 双频覆盖兼容传感器节点的低功耗通信与网关的高带宽数据回传。

2. 物联网终端设备

  • 40mm×8mm小型化设计适配智能电表、安防摄像头、智能家居设备等紧凑终端;
  • 50Ω阻抗与IPEX接口易集成于PCB板,无需额外空间。

3. 短距离高功率通信

  • 50W功率耐受支持无人机遥控、无线充电控制、工业遥控器等大功率通信场景;
  • 双频特性可同时传输控制信号(2.4GHz)与视频数据(5.8GHz)。

4. 车载无线系统

  • 宽温范围适配车载环境(-40℃低温启动、+80℃夏季高温);
  • 双频兼容车载Wi-Fi、蓝牙音频、车联网(V2X)等多协议。

四、环境适应性设计

针对工业与户外场景的极端环境,该天线做了以下优化:

  • 宽温工作:-40℃~+80℃的温度范围,无需额外温控装置即可稳定运行;
  • 抗干扰设计:5.8GHz频段避开2.4GHz的Wi-Fi、蓝牙拥挤环境,提升通信可靠性;
  • 小型化耐候性:紧凑尺寸适合内置安装,避免户外安装时的体积限制。

五、物理与接口特性

  • 尺寸:40mm(长度)×8mm(宽度),采用扁平式设计,可贴装于PCB板或内置设备外壳;
  • 接口:IPEX射频接口(常见小型化射频接口),支持与射频模块的快速插拔连接;
  • 集成方式:无特殊封装要求,适配贴片、焊接等多种集成方式,降低系统设计难度。

总结:BW258PNX40-8B1是一款工业级双频小型化天线,凭借双频兼容、高功率耐受、宽温稳定等特性,成为物联网、工业无线、车载通信等领域的高性价比选择,可有效简化系统设计并提升信号传输可靠性。

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
