KH-MMCX-JE RF射频同轴连接器产品概述

KH-MMCX-JE是金航标(Kinghelm)推出的板端射频同轴连接器,属于MMCX系列,专为小型化射频设备的信号传输设计,兼顾高性能、高可靠性与易安装性,是物联网、无线通信、测试仪器等领域的核心连接组件。

一、产品核心定位与应用场景

KH-MMCX-JE聚焦小型化射频设备的信号互联,针对空间紧凑、多接口集成的设计需求优化,核心应用场景覆盖:

  • 物联网终端:LoRa/NB-IoT网关、智能传感器节点的天线与模块连接;
  • 无线通信模块:WiFi 6/蓝牙5.0/5G Sub-6G模块的射频输出接口;
  • 测试仪器:手持频谱仪、信号发生器的板端信号接口;
  • 消费电子:智能手表、蓝牙耳机的天线连接;
  • 工业无线:工业遥控器、无线PLC的射频传输。

其尺寸比SMA连接器缩小约60%,可有效降低设备体积,适配高密度PCB布局。

二、关键性能参数解析

KH-MMCX-JE的射频性能与电气参数满足行业主流需求,核心指标如下:

  • 特性阻抗:50Ω(射频标准阻抗,匹配多数模块/线缆);
  • 频率范围:0~6GHz(覆盖WiFi、蓝牙、LoRa等主流无线频段);
  • 驻波比(VSWR):DC3GHz ≤1.2,36GHz ≤1.5(低反射保证信号完整性);
  • 插入损耗:DC3GHz ≤0.15dB,36GHz ≤0.3dB(信号传输损耗小);
  • 插拔寿命:≥500次循环(支持多次调试与维护);
  • 温湿度范围:工作-40℃+85℃,存储-55℃+100℃,湿度95%RH(40℃)。

三、结构设计与工艺特点

KH-MMCX-JE采用模块化精密设计,兼顾性能与可靠性:

  1. 接触件:黄铜基体+镀金(金层厚度≥0.5μm),接触电阻≤10mΩ,耐腐蚀且信号传输稳定;
  2. 绝缘件:PTFE(聚四氟乙烯)材料,介电常数稳定(ε=2.1)、耐高温,避免温湿度变化影响射频性能;
  3. 外壳:黄铜基体+镀镍,防腐蚀同时提供可靠射频屏蔽与接地;
  4. 板端结构:直插焊端设计,适配0.8mm及以上厚度PCB板,高度仅约5mm,适配狭小空间。

四、安装与适配性说明

KH-MMCX-JE的安装与适配性经过优化,降低设计生产难度:

  • 安装方式:支持通孔焊接与表面贴装(SMT),焊接温度需控制:回流焊≤260℃(30s内)、波峰焊≤240℃(10s内),避免损坏PTFE绝缘件;
  • 适配性:可与MMCX系列公/母头线缆连接器(如KH-MMCX-KW、KH-MMCX-JW)直接配合,兼容行业标准MMCX接口,互换性良好;
  • 注意事项:安装时保证焊盘与连接器中心对齐,避免偏斜;建议预留0.5mm以上接地焊盘增强屏蔽。

五、可靠性与典型应用案例

KH-MMCX-JE通过严格可靠性测试,满足多场景需求:

  • 可靠性验证:通过48h中性盐雾试验、10~2000Hz振动(10g)、100g冲击(11ms)测试,性能无明显下降;
  • 典型案例:
    1. 智能手表:小型化设计适配狭小内部空间,连接蓝牙/WiFi天线;
    2. LoRa网关:高密度布局支持多通道射频接口集成;
    3. 工业传感器:耐振动宽温特性,适应工业环境长期稳定工作。

KH-MMCX-JE作为金航标MMCX系列核心板端产品,凭借小型化、高性能、高可靠性优势,成为各类小型射频设备的首选连接方案,可有效降低研发成本,提升产品竞争力。

WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.

Electronic component model and package intelligence review on an ESD-safe inspection bench

Model & package intelligence

Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.

BOM matching and alternative component comparison workstation with protected IC samples

BOM matching & alternatives

BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.

Electronic component sourcing availability dashboard with ESD-protected samples

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
