KH-SMA-KWE17-G RF射频同轴连接器产品概述

一、产品核心定位与应用方向

KH-SMA-KWE17-G是金航标(kinghelm)推出的单端口板端射频同轴连接器,主打高频传输与紧凑布局场景。作为SMA系列衍生型号,它针对PCB板上的射频信号输入/输出需求设计,特别适配对空间、频率、宽温适应性有要求的设备——比如射频测试仪器、5G基站模块、卫星通信终端等高频应用。核心优势是“18GHz高频覆盖+90°弯头紧凑设计+宽温可靠”,解决了传统直头连接器在空间受限、极端温度下的应用痛点。

二、关键技术参数与实际意义

这款连接器的参数并非数字堆砌,每个指标都对应实际需求:

  1. 频率范围18GHz:覆盖Ku波段(12-18GHz),是卫星通信、5G毫米波(部分频段)、射频测试的常用频段,能满足高速数据传输、低损耗信号传输要求;
  2. 阻抗50Ω:射频系统标准阻抗,与绝大多数射频设备、传输线(如RG174/RG316同轴线)匹配,大幅减少信号反射,提升传输效率;
  3. 板端插件式:采用插件封装(非贴片),通过PCB焊盘固定,机械强度更高,适合批量生产中人工/自动焊接;
  4. 90°弯头设计:接口与PCB呈90°,解决直头在垂直空间不足的问题(比如设备内部紧凑场景),让射频线布线更灵活;
  5. 宽温范围-55℃~+155℃:覆盖户外基站(低温-40℃)、航空航天辅助设备(极端高低温)等场景,无需额外防护即可稳定工作;
  6. 内孔接口(SMA母头):SMA-K系列标准定义(K代表内孔母头),与标准SMA公头(针式)完美匹配,互换性强,无需担心接口不兼容。

三、结构设计与工艺优势

  1. 紧凑弯头结构:弯头角度经过阻抗优化,既保证信号低损耗(避免过度弯曲导致阻抗突变),又节省30%以上垂直空间,适配小型化射频设备;
  2. 镀金触点+黄铜壳体:触点镀金厚度≥0.5μm,耐腐蚀、抗氧化,长期使用仍保持稳定导电;壳体选用高强度黄铜,电磁屏蔽效果好,减少外界干扰;
  3. 插件焊接可靠性:引脚长度与PCB焊盘匹配,回流焊/波峰焊均可(温度≤260℃,时间≤10秒),焊接后机械强度高,插拔寿命≥500次。

四、安装与使用注意事项

  1. 焊接温度控制:避免高温损坏内部绝缘材料,回流焊温度不超过260℃,单次焊接时间≤10秒;
  2. 阻抗匹配要求:确保PCB射频走线阻抗为50Ω(通过微带线/带状线设计实现),否则会导致信号反射;
  3. 接口清洁:使用前避免沾染灰尘/油污,定期用无水乙醇擦拭,保证接触良好;
  4. 插拔规范:插拔SMA公头时,旋转角度≤15°,防止损坏内孔触点。

五、典型应用场景

  1. 射频测试仪器:信号发生器、频谱分析仪、网络分析仪的板端接口,满足18GHz内测试需求;
  2. 5G/4G基站模块:基站射频单元(RRU)的PCB板端接口,适应户外宽温环境;
  3. 卫星通信终端:卫星接收/发射设备的高频模块,覆盖Ku波段信号传输;
  4. 工业射频设备:RFID读写器、无线传感器的高频模块,满足工业级宽温要求;
  5. 航空航天辅助设备:机载射频组件的PCB接口,适应高空极端温度环境。

KH-SMA-KWE17-G凭借高频覆盖、紧凑布局、宽温可靠的特点,成为中小功率射频设备板端接口的优选方案,能有效提升设备射频性能与环境适应性。

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
