BWGNSCNX18-18W4 产品概述
一、产品简介
BWGNSCNX18-18W4 是 BAT WIRELESS（蝙蝠无线）推出的一款高性能陶瓷饼片式无源GPS/北斗天线。天线采用陶瓷材料制造，封装为插件式（18×18mm），尺寸为18mm×18mm×4mm，适合空间受限的终端设备。中心频率为1.57542GHz（GPS L1），在10MHz带宽内实现稳定接收性能，广泛用于定位与导航类终端。
二、主要规格
- 天线类型：陶瓷天线（无源）
- 中心频率：1.57542 GHz（GPS L1）
- 带宽：10 MHz
- 增益：3 dBi
- 阻抗：50 Ω
- 最大功率：50 W
- 驻波比（SWR）：1.8
- 工作温度：-40 ℃ ~ +80 ℃
- 尺寸：18 × 18 × 4 mm
- 封装：插件，18×18mm
三、性能特点
- 小型化设计，适配紧凑型电路板和嵌入式设备。
- 增益约3 dBi，主瓣覆盖良好，满足常见的车载、手持与固定式定位场景。
- 无源结构，抗干扰性好、可靠性高，无需外部供电或LNA（可根据系统需求外接低噪放大器）。
- 宽工作温度范围，适应工业级环境与车载应用。
四、安装与布局建议
- 推荐与50 Ω传输线直接匹配，使用阻抗连续的射频走线以降低反射损耗。
- 驻波比为1.8，若需更低的VSWR可在天线馈入处加入简单匹配网络（例如L型或PI型电感/电容网络）进行优化。
- 天线周围应留出铜箔空白区（地平面边缘保持适当距离），避免金属件或大面积地平面近距离遮挡天线辐射。
- 插件安装需保证焊点牢固并与天线引脚形成良好电气连接，避免应力导致断裂。
- 建议在样机阶段进行驻波和场型测试，调整天线位置以获得最佳接收灵敏度。
五、典型应用场景
- 车载导航模块、行车记录仪定位子系统
- 便携式GPS定位终端与手持设备
- 物联网追踪器、资产管理标签
- 无人机定位与导航辅助设备
- 工业与农业定位控制终端
六、工作与可靠性
天线额定功率50W，远高于接收类终端实际需求，保证在异常发射条件下具有足够裕量。陶瓷材料具备良好温度稳定性与机械强度，适用于-40 ℃至+80 ℃的工作环境。插件结构便于批量装配与维修更换。
七、注意事项与建议
- 本品为无源天线，如需提升接收灵敏度可配合低噪声放大器（LNA）使用，但注意LNA与天线之间的匹配和馈线损耗。
- 若需覆盖多系统（如GPS+北斗），建议在系统层面评估频带重合与性能要求；本天线以GPS L1为设计中心，对北斗B1等相邻频段具有一定接收能力，但性能最佳点为1575.42 MHz。
- 推荐在最终产品中进行实地定位测试，确认抗多径与遮挡情况下的实用性能。
BWGNSCNX18-18W4 以其紧凑尺寸、稳定性能与工业级可靠性，适合对体积与成本敏感的定位产品，是GPS/北斗接收终端的优选陶瓷天线解决方案。若需器件封装图、贴装图或更多电气测试数据，可向 BAT WIRELESS 技术支持索取详细资料。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
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.
