金航标KH-SMA-K513-G射频同轴连接器产品概述

金航标KH-SMA-K513-G是一款专为6GHz以下射频信号传输设计的板端内孔同轴连接器,采用插件式封装与90°弯头结构,具备50Ω标准阻抗、宽温适应性等核心特性,广泛适配无线通信、射频测试、工业控制等场景的设备板端连接需求。

一、产品核心定位与典型应用场景

该连接器属于金航标SMA射频系列的板端专用型号,针对PCB板上的射频信号输入/输出设计,内孔接口(母头) 与标准SMA公头直接适配,单端口配置满足单路射频信号传输需求。典型应用包括:

  • 无线通信领域:5G小基站、WiFi6模块、卫星通信终端的板端信号接口;
  • 射频测试设备:信号发生器、频谱分析仪、网络分析仪的板载测试接口;
  • 工业与汽车电子:工业物联网网关、车联网T-Box、车载雷达的射频连接;
  • 极端环境场景:航空航天辅助设备、户外通信基站(-40℃~+85℃)、高温工业设备(如烤箱附近)的板端连接。

二、关键性能参数解析

1. 频率与阻抗匹配

  • 频率范围:6GHz,覆盖2.4GHz、5GHz、Sub-6GHz等主流射频频段,满足大多数民用与工业射频设备的信号传输需求;
  • 阻抗:50Ω(SMA标准阻抗),与射频电缆、PCB板传输线的阻抗匹配一致,可有效降低信号反射损耗,驻波比(VSWR)典型值≤1.2@6GHz,保证信号完整性。

2. 环境与机械参数

  • 工作温度:-55℃~+155℃,覆盖工业级(-40℃~+85℃)与部分军标级温度范围,可在极端高低温环境下长期稳定工作;
  • 封装类型:插件式(DIP),引脚设计符合PCB板焊接规范,适合波峰焊、手工焊等批量生产工艺;
  • 接口样式:90°弯头,避免直头占用垂直空间,适配PCB板边缘、内部密集布局的安装场景。

三、结构设计与工艺特点

1. 弯头结构优化

90°弯头设计使连接器轴线与PCB板呈垂直/平行关系,可灵活调整连接方向,解决设备内部空间受限问题,同时减少射频电缆的弯折应力,延长电缆使用寿命。

2. 精密接触与材料

  • 接触件:采用黄铜材质+镀金/镀镍处理,保证接触电阻低(典型值≤10mΩ),连接稳定可靠;
  • 绝缘体:使用PTFE(聚四氟乙烯),介电常数稳定(ε≈2.0),耐高温、耐老化,保证电气性能一致性;
  • 外壳:黄铜镀镍,抗腐蚀、抗磨损,适合户外或高湿度环境。

3. 插件封装优势

插件引脚与PCB板焊盘直接焊接,机械强度高,抗振动与冲击性能优于贴片封装,可承受IEC 60068-2-6标准下的振动测试(10~2000Hz,加速度2g)。

四、安装与兼容性说明

1. 安装注意事项

  • PCB板需预留对应焊盘与安装孔(需匹配连接器引脚间距与尺寸);
  • 焊接温度控制在260℃±10℃,焊接时间≤3秒/引脚,避免高温损坏绝缘体;
  • 安装后需检查引脚焊接是否牢固,无虚焊、假焊现象。

2. 兼容性适配

  • 与标准SMA公头连接器(如金航标KH-SMA-J系列)完全兼容;
  • 适配RG174、RG316、RG58等常见射频电缆组件;
  • 可与各类射频前端模块(如PA、LNA)的板端接口直接对接。

五、可靠性与环境适应性

该产品通过多项可靠性测试,满足工业级应用要求:

  • 盐雾测试:符合GB/T 2423.17,500小时盐雾暴露后无腐蚀、接触电阻无明显变化;
  • 温度循环:-55℃~+155℃循环100次后,电气性能保持稳定;
  • 插拔寿命:≥500次插拔,接触性能无衰减。

金航标KH-SMA-K513-G凭借稳定的射频性能、灵活的安装设计与宽温适应性,成为各类射频设备板端连接的优选方案,可有效提升设备的信号传输质量与可靠性。

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
