KH-SMA-KE8-G RF射频同轴连接器产品概述

KH-SMA-KE8-G是金航标(kinghelm) 旗下SMA系列的核心板端插件型号,专为射频领域的PCB板级信号可靠连接设计,兼顾紧凑布局与高频传输性能,是通信、测试仪器及电子设备的通用连接方案。

一、产品核心定位与应用方向

作为SMA射频同轴连接器的衍生型号,KH-SMA-KE8-G聚焦设备内部射频模块与外部天线/仪器的板级接口,解决中高频段(DC-18GHz)信号的匹配传输问题。其设计适配多场景下的空间限制,可覆盖通信、测试、消费电子及工业控制等领域,满足批量生产与长期稳定运行需求。

二、关键参数与物理特性

该产品的参数严格匹配射频连接的基础要求,核心信息如下:

  1. 基础接口属性:
    • 连接器类型:板端插件(垂直安装,偏脚布局);
    • 接口类型:内孔(SMA母头,兼容标准SMA公头外螺纹连接);
    • 端口数量:单端口(独立射频信号通道);
    • 物理高度:接口顶端至PCB板高度为8mm,适配薄型设备空间。
  2. 射频性能参数:
    • 特性阻抗:50Ω(SMA系列标准阻抗,保证信号无反射);
    • 工作频率:DC-18GHz(覆盖2.4GHz、5GHz、LTE等主流射频频段);
    • 驻波比(VSWR):DC-6GHz≤1.15,6-18GHz≤1.2(低反射损耗,提升信号完整性);
    • 接触电阻:内导体≤5mΩ,外导体≤2mΩ(减少接触损耗)。
  3. 材料与工艺:
    • 导体:黄铜(内导体)+ 磷青铜(外导体),导电性能优异;
    • 表面处理:内导体镀金(抗腐蚀、提升接触可靠性),外导体镀镍(抗磨损);
    • 绝缘:PTFE(聚四氟乙烯),耐高温(-55℃~+125℃)、低损耗。

三、结构设计优势

KH-SMA-KE8-G针对板级应用痛点优化,具备3大核心优势:

  1. 偏脚布局适配紧凑空间:
    引脚偏离中心位置,避免与PCB板上电容、电阻等元件干涉,可在高密度布局中灵活安装,提升设备集成度。
  2. 内孔母头连接可靠:
    内孔设计匹配标准SMA公头外螺纹,插拔力适中(10-20N),连接紧密不易松动,插拔寿命≥500次。
  3. 板端插件安装简便:
    插件式焊接固定,无需额外工装,适合批量生产;焊点牢固,可承受振动环境(振动测试:10-2000Hz,加速度10g)。

四、典型适用场景

该产品的性能与设计使其适用于多类射频设备:

  • 通信设备:基站射频模块、5G小基站、无线AP的天线接口;
  • 测试仪器:信号发生器、频谱分析仪、网络分析仪的内部连接;
  • 消费电子:无人机图传模块、智能家居网关、蓝牙/WiFi模块;
  • 工业控制:工业无线传感器、远程监控设备的射频接口。

五、品牌与品质保障

金航标(kinghelm)作为国内射频连接器专业品牌,KH-SMA-KE8-G符合RoHS环保标准,通过ISO9001认证,每批产品经阻抗测试、VSWR测试及插拔寿命测试,确保一致性。其材料与工艺适配工业级环境,可在-55℃~+125℃下稳定运行。

总结:KH-SMA-KE8-G以紧凑偏脚设计、可靠射频性能及简便安装方式,成为板级射频连接的高性价比选择,满足各类设备对信号传输的稳定需求。

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
