KH-MCX-KE-STM RF射频同轴连接器产品概述

一、产品核心定位与典型应用场景

KH-MCX-KE-STM是金航标(kinghelm)推出的SMD封装MCX系列板端射频同轴连接器,专为小型化、高密度射频电路设计,兼顾信号传输性能与自动化生产适配性,核心解决传统SMA连接器体积过大、直插封装不适合自动化贴装的痛点。

典型应用场景包括:

  1. 无线通信终端:WiFi6/6E模块、蓝牙5.3/5.4低功耗模块、5G Sub-6G小基站;
  2. 物联网(IoT)设备:智能传感器节点、智能家居网关、工业无线遥测终端;
  3. 医疗电子:便携式监护仪、远程医疗设备的射频信号接口;
  4. 消费电子:智能穿戴(智能手表/手环的蓝牙/WiFi天线接口)、无人机图传模块。

二、关键技术参数(核心性能指标)

指标项 具体参数 备注说明 特性阻抗 50Ω 射频同轴通信标准阻抗 频率范围 DC-6GHz 覆盖2.4G/5.8G/Sub-6G主流频段 接触电阻 ≤10mΩ 镀金接触件保障低损耗 绝缘电阻 ≥1000MΩ(DC 500V) PTFE绝缘体抗漏电 耐电压 750V AC(50Hz,1s) 无击穿/飞弧 焊接方式 SMD(表面贴装) 适配回流焊/波峰焊 插拔寿命 ≥500次 按压锁合结构稳定 工作温度范围 -40℃~+85℃ 宽温适应工业/户外场景

三、结构设计与工艺优势

  1. 小型化适配:MCX系列体积仅为SMA连接器的1/3左右,SMD封装无引脚突出,节省PCB空间(占用面积约5mm×5mm),完美适配智能穿戴、小型传感器等紧凑设备;
  2. 可靠连接结构:采用按压式锁合机制,插拔便捷且锁定牢固(拔插力≥10N),避免振动场景下松动导致信号衰减;
  3. 优质材料选型:
    • 接触件:黄铜镀金(厚度≥0.5μm),耐腐蚀、降低接触电阻;
    • 绝缘体:PTFE(聚四氟乙烯),低介质损耗(tanδ≤0.0002@1GHz),耐高温老化;
    • 外壳:锌合金镀镍,抗电磁干扰(EMI),机械强度高(抗冲击≥1000g);
  4. 自动化生产适配:SMD封装符合IPC-7351标准,可通过自动化贴片机批量生产,生产效率比直插封装提升30%以上,降低人工成本。

四、安装与兼容性说明

  1. PCB设计要求:
    • 焊盘尺寸:中心接触件焊盘直径Φ1.6mm,外壳焊盘宽度2.0mm;
    • 阻抗匹配:需在PCB上设计50Ω微带线(线宽参考金航标官方Layout指南),避免信号反射;
  2. 焊接工艺规范:
    • 回流焊:预热150-180℃(60-120s)→ 升温速率≤2.5℃/s → 峰值230-250℃(10-20s)→ 冷却速率≤3℃/s;
    • 波峰焊:焊接时间≤3s(避免高温损坏PTFE绝缘体),焊料温度240-250℃;
  3. 兼容性:
    • 匹配公头:兼容金航标KH-MCX-J系列SMD/直插公头;
    • 模块适配:支持ESP32、CC1352、nRF52840等主流物联网/无线通信模块的射频接口。

五、品牌与品质保障

金航标(kinghelm)是国内专注射频连接器10余年的专业厂商,KH-MCX-KE-STM具备:

  • 认证资质:ISO9001质量管理体系认证、RoHS2.0/REACH环保认证;
  • 品质管控:100%全检接触电阻、绝缘电阻,每批次抽样测试插拔寿命(500次)、耐温循环(-40℃~+85℃,100次);
  • 技术支持:提供免费PCB Layout指导、样品测试服务,可响应定制需求(如特殊封装、镀金厚度调整)。

KH-MCX-KE-STM凭借小型化、高性能、自动化适配等优势,成为无线通信、物联网等领域小型化射频电路的优选板端连接器方案。

Product sourcing intelligence

Model, package, availability, and BOM fit reviewed before quotation.

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
