BWGNSCNX20-20W4 — 陶瓷GPS/北斗无源天线产品概述
一、产品简介
BWGNSCNX20-20W4 是 BAT WIRELESS（蝙蝠无线）推出的一款高性能陶瓷片式无源定位天线，针对卫星导航接收应用优化设计。天线中心频率为 1.57542 MHz（GPS L1），带宽 10 MHz，尺寸紧凑（20 × 20 × 4 mm），适合空间受限的嵌入式与消费类终端使用。
二、主要特性
- 陶瓷天线结构，体积小、稳定性高、耐候性强。
- 中心频率：1.57542 GHz（GPS L1）；带宽：10 MHz，满足单频定位接收需求。
- 增益：3 dBi，50 Ω 阻抗匹配，典型驻波比（VSWR）≤ 1.8。
- 最大承受功率：50 W（瞬时或发射链路保护用值，请按系统要求评估）。
- 工作温度范围：-40 ℃ 至 +80 ℃，适应工业级环境。
- 封装形式：插件（through-hole），便于板载安装与可靠焊接。
三、典型应用场景
- 车载导航与物流跟踪终端
- 无人机与遥感平台定位模块
- 可穿戴定位设备与手持导航仪
- 智能物联网定位节点、安防与远程抄表等场合
四、安装与使用建议
- 本件为无源天线，终端需配合接收端前端（如LNA、滤波器或定位模块）共同工作以获得最佳灵敏度。
- 建议天线与接收器之间采用 50 Ω 同轴短连线，避免过长馈线带来损耗与失配。
- 天线周围的金属结构和地平面尺寸会影响辐射方向图与增益，安装时应预留足够非金属覆盖区域并根据机壳设计优化地平面。
- 焊接与插件时注意温度曲线与力学应力，避免损伤陶瓷基体。
五、典型电气与机械参数
- 中心频率：1.57542 GHz
- 带宽：10 MHz
- 增益：3 dBi
- 阻抗：50 Ω
- 驻波比（VSWR）：≤ 1.8
- 最大功率：50 W
- 工作温度：-40 ℃ ~ +80 ℃
- 外形尺寸：20 mm × 20 mm × 4 mm
- 封装：插件，20×20 mm
六、选型与兼容性提示
本天线为单频接收型器件，适用于以 GPS L1 为主的定位系统。若需多频或更高精度（如 RTK）应用，请选择支持多频和主动放大功能的天线或在接收端增加对应前端电路。对于北斗等其他频段兼容性，请在实际系统中进行频谱与灵敏度验证。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
