SMA-KE-347-H13.5-1.6 RF射频同轴连接器产品概述

SMA-KE-347-H13.5-1.6是讯普(XUNPU)推出的单端口板端射频同轴连接器,属于SMA射频系列,针对3GHz以下射频信号传输场景设计,采用DIP插件封装与偏脚结构,兼顾小型化布局与稳定信号传输需求,广泛适配通信、测试、工业等领域的射频信号接入场景。

一、产品核心定位与品牌背景

讯普(XUNPU)作为专注射频连接器研发的厂商,聚焦中低频射频传输的小型化、高可靠解决方案。SMA-KE-347-H13.5-1.6定位于低成本、高适配性的板端射频接口,针对PCB板上的单点射频信号接入需求,解决传统SMA连接器在紧凑布局下的安装干涉问题,同时满足3GHz以内信号的低损耗传输要求。

二、关键技术参数解析

1. 频率与阻抗特性

  • 频率覆盖:3GHz以内,兼容蓝牙(2.4GHz)、WiFi(2.4/5GHz)、RFID等主流无线频段,满足大多数中低频射频信号传输;
  • 阻抗匹配:50Ω标准射频阻抗,与全球通用射频系统(如信号发生器、无线模块)完全兼容,避免信号反射,降低传输损耗。

2. 接口与结构参数

  • 接口类型:内孔式SMA母头(对应SMA公头),接触可靠,插拔寿命符合行业标准;
  • 端口数量:单端口设计,适合单点射频信号独立接入,避免多端口干扰;
  • 封装与安装:DIP插件封装,需配合PCB钻孔焊接;偏脚结构(引脚偏离中心),适配PCB元件密集的紧凑布局,节省空间。

3. 电气与机械性能

  • 接触电阻:≤10mΩ(内导体),保证信号低损耗;
  • 绝缘电阻:≥1000MΩ(DC500V),避免漏电与串扰;
  • 插拔寿命:≥500次,满足设备调试维护需求。

三、结构设计与工艺特点

1. 材质与防护

  • 外导体:黄铜镀镍,耐腐蚀、抗磨损,适合工业环境长期使用;
  • 内导体:铍铜镀金,弹性好、导电性优,保证接触可靠性;
  • 绝缘介质:PTFE(聚四氟乙烯),耐高温(-65℃~165℃)、低介质损耗,确保3GHz下信号稳定传输。

2. 偏脚结构优化

引脚采用偏移式设计(偏离连接器中心轴线),避免与PCB上电容、电阻等元件引脚干涉,适配智能穿戴、无线模块等小型化设备的高密度布局。

3. 焊接可靠性

DIP引脚加粗设计,焊接时受热均匀,避免虚焊;引脚长度匹配常规PCB厚度(1.6mm),安装后与PCB贴合紧密,机械稳定性强。

四、典型应用场景

1. 无线通信模块

蓝牙/WiFi模块、LoRa模块的射频输入接口,适配2.4/5GHz频段,满足模块小型化布局需求;

2. 测试测量仪器

便携式信号发生器、示波器的板端射频接口,兼容3GHz以内信号测试,插拔便捷;

3. 工业控制设备

远程无线传感器、PLC的射频接入端,耐工业环境腐蚀,稳定传输控制信号;

4. 消费电子

智能穿戴(智能手表、手环)的蓝牙射频接口,偏脚设计适配小型PCB,节省空间。

五、安装与兼容性说明

1. 安装注意事项

  • 焊接温度:推荐260℃~300℃,单引脚焊接时间≤3秒,避免过热损坏PTFE介质;
  • PCB钻孔:孔径匹配引脚尺寸(1.0mm~1.2mm),精度控制在±0.1mm以内,保证焊接牢固;
  • 方向确认:偏脚结构需注意引脚方向与PCB布局匹配,避免干涉其他元件。

2. 兼容性说明

  • 接口兼容:匹配标准SMA公头连接器(如RG174、RG316电缆的SMA公头);
  • 系统兼容:适配50Ω射频系统,可与大多数品牌无线模块、测试仪器对接,无需额外阻抗匹配。

这款SMA-KE-347-H13.5-1.6连接器以高适配性、小型化、低成本为核心优势,针对中低频射频传输的实际需求优化设计,是通信、测试、工业等领域板端射频接口的实用选择。

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
