BWSMA-KE-P001是BAT WIRELESS(蝙蝠无线) 针对板级射频信号连接需求推出的单端口SMA母头连接器,核心聚焦50Ω阻抗匹配下的单路射频信号稳定传输,适配多种通信、测试、工业场景:
该产品参数围绕射频性能、机械兼容与安装适配性设计,核心参数及技术意义如下:
参数项 具体规格 技术价值 连接器类型 板端(插件式) 直接焊接PCB板,实现板级信号引出/接入,无需额外转接件 接口类型 内孔(SMA母头) 中心接触件为孔状,适配SMA公头线缆的中心针,避免针脚弯曲损坏 端口数量 1 单通道传输,适合单路射频信号的独立连接需求 接口直径 5.2mm 符合SMA系列标准尺寸,与主流SMA线缆/连接器完全兼容 射频阻抗 50Ω 匹配90%以上射频电路的标准阻抗,降低信号反射与驻波比(VSWR) 安装样式 偏脚设计 引脚偏离中心轴线,优化PCB布局,避免与周边电容、电阻等元件干涉 品牌 BAT WIRELESS 专注射频连接器研发,产品通过工业级可靠性测试BWSMA-KE-P001的结构设计兼顾射频性能稳定性与安装便利性,核心工艺特点包括:
偏脚插件适配性
引脚采用非中心对称布局,可根据PCB板元件分布灵活调整焊接位置;插件式引脚长度适配1.6mm标准板厚,支持波峰焊、手工焊两种工艺,无需特殊治具。
低损耗射频结构
机械可靠性
接口螺纹符合SMA标准(M5×0.5),连接力矩≤0.5N·m,避免过紧损坏;引脚采用冲压成型工艺,强度高,焊接后不易脱落。
为保障产品性能与使用寿命,安装使用需注意以下要点:
PCB焊盘适配
确认PCB板偏脚焊盘的位置、孔径(φ0.8mm~φ1.0mm)与产品引脚匹配,避免虚焊或焊接困难。
焊接温度控制
手工焊烙铁温度控制在260℃±10℃,焊接时间≤3秒/引脚;波峰焊温度≤250℃,避免高温损坏PTFE绝缘材料。
连接操作规范
与SMA公头线缆连接时,使用力矩扳手控制力矩(0.3~0.5N·m),禁止野蛮插拔;闲置时搭配防尘盖保护接口。
性能验证
安装后通过矢量网络分析仪测试VSWR,要求DC~6GHz范围内≤1.2,确保信号传输质量。
BAT WIRELESS作为国内射频连接器专业品牌,BWSMA-KE-P001具备以下优势:
该产品以高性价比、稳定的射频性能,成为板级射频连接的优选方案,广泛适配通信、测试、工业等领域的单路信号传输需求。
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.
