KH-SMA-P-8029 RF射频同轴连接器产品概述

一、产品基本属性与定位

KH-SMA-P-8029是金航标(Kinghelm)SMA系列射频同轴连接器的板端专用型号,核心定位为小型化设备的PCB板端射频信号连接,采用内孔接口+90°弯头结构,适配单端口射频信号传输场景。该型号的基础参数清晰匹配射频设备的紧凑布局需求,具体如下:

  • 连接器类型:板端(直接焊接于PCB板)
  • 接口类型:内孔式(SMA母头,中心孔+外螺纹设计)
  • 端口数量:单端口(1路独立射频信号传输)
  • 接口直径:5.25mm(含外螺纹的接口外径,符合SMA标准尺寸)
  • 板高/接口长度:14mm(从PCB焊接面到接口端面的垂直高度)
  • 封装形式:插件式(引脚直插PCB,需焊接固定)

二、核心设计与性能优势

1. 弯头结构解决空间适配问题

该型号采用90°直角弯头设计,打破了SMA直头连接器在PCB板端的空间限制:当设备内部射频模块与外部接口呈垂直布局时,弯头可直接转向,无需额外弯折射频线缆,既减少信号传输损耗(弯曲损耗≤0.1dB@3GHz),又避免直头突出占用额外体积,适配便携式仪器、车载终端等小型化场景。

2. 内孔接口保障信号稳定性

作为SMA标准内孔母头,KH-SMA-P-8029的中心导体与外导体采用高精度机械加工,插拔公差控制在±0.02mm以内,与对端SMA公头(内针)配合紧密;外导体螺纹镀镍处理,抗氧化性强,插拔寿命可达1000次以上,长期使用后仍能保持50Ω阻抗匹配(反射系数≤-20dB@DC-6GHz)。

3. 插件封装提升焊接可靠性

插件式引脚设计适配常规PCB板厚度(1.6mm为主流),焊接时引脚穿透PCB板,波峰焊或手工焊后形成牢固的机械连接与电气导通——相比表贴封装,可有效降低振动环境下的虚焊风险,适合工业级、车载级等对可靠性要求较高的场景。

4. 尺寸参数兼容主流设计

接口直径5.25mm、板高14mm的参数符合多数射频设备的PCB布局规范,无需修改板设计即可直接替换同类SMA板端弯头连接器,降低研发与改造成本。

三、典型应用场景

KH-SMA-P-8029的设计特性使其在以下场景中具有显著优势:

  1. 便携式射频仪器:手持信号发生器、频谱分析仪等设备,内部PCB与外部测试接口垂直布局,弯头减少空间占用;
  2. 车载射频终端:车载导航、车联网模块,射频信号从PCB转向外部天线,适配车身紧凑空间;
  3. 工业无线模块:LoRa、Wi-Fi工业控制模块,插件封装抗振动,适合 harsh环境;
  4. 微基站/皮基站:小型通信基站内部射频板端连接,单端口设计适配单天线信号传输。

四、选型与使用注意事项

1. 对端匹配要求

需搭配SMA内针公头(如金航标KH-SMA-J系列)使用,禁止与MCX、BNC等非SMA接口直接连接,避免接口损坏或信号损耗;

2. 焊接规范

  • PCB焊盘直径≥1.2mm,焊接温度:手工焊≤260℃(3秒内完成),波峰焊240-250℃;
  • 避免高温损坏连接器内部绝缘材料(工作温度范围-40℃~+85℃);

3. 阻抗匹配

PCB射频走线需保持50Ω阻抗,与连接器一致,减少信号反射;

4. 环境适配

常规版本适合-40℃~+85℃环境,若需更高温/低温场景,需确认定制化版本。

五、品质与认证

金航标作为国内射频连接器主流厂商,KH-SMA-P-8029采用RoHS环保材料,通过ISO9001质量体系认证,每批次产品均经过:

  • 插拔寿命测试(1000次无失效);
  • 阻抗测试(50Ω±2Ω);
  • 绝缘电阻测试(≥1000MΩ@500V DC); 确保性能一致性与可靠性。

该型号凭借紧凑设计、稳定性能与高可靠性,成为小型化射频设备板端连接的优选方案。

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
