KH-BNC50-3511 RF射频同轴连接器产品概述

KH-BNC50-3511是金航标(kinghelm)针对PCB板级射频信号传输推出的一款弯头内孔式连接器,以紧凑布局、稳定阻抗匹配为核心优势,适配中低频段射频系统的单通道连接需求,广泛应用于通信、测试、工业等领域。

一、产品定位与核心应用场景

作为BNC系列射频连接器的板端衍生型号,KH-BNC50-3511主要面向空间受限的板级信号连接场景,典型应用包括:

  1. 无线通信设备:基站射频模块、小基站(pico基站)的板端信号接口,适配2.4GHz、3GHz以下的WiFi、GSM、LTE频段;
  2. 射频测试仪器:信号发生器、频谱分析仪、网络分析仪的PCB内置接口,满足测试设备的板级信号输入输出需求;
  3. 工业控制:工业物联网(IIoT)射频数据模块、远程监测设备的板端信号连接;
  4. 医疗电子:低噪射频医疗设备(如监护仪、成像设备)的板级接口,适配宽温环境下的稳定工作。

二、核心技术参数详解

KH-BNC50-3511的参数严格遵循BNC射频标准,关键指标匹配主流系统需求:

  1. 射频核心参数:50Ω特性阻抗(与BNC通用阻抗一致),频率范围DC~3GHz,覆盖中低频段射频信号无失真传输;
  2. 接口与结构:单端口设计,板端为内孔式(适配公头外针),接口直径9.5mm(BNC标准尺寸),弯头(90°转角)节省PCB布局空间;
  3. 环境参数:工作温度-55℃~+155℃,覆盖极端低温(户外)与高温(工业烤箱)场景,环境适应性强。

三、结构设计与工艺特点

  1. 板端插件式设计:采用插件安装方式,适配PCB插件孔布局,支持手工焊接或波峰焊,安装便捷且可靠性高;
  2. 内孔接触结构:接触件为内孔式,与公头外针紧密配合,接触电阻≤20mΩ,插拔寿命≥1000次,长期使用信号稳定;
  3. 材料与工艺:接触件选用高导电磷青铜,表面镀金(≥0.5μm),兼具低阻抗与防腐蚀;绝缘件采用耐高温PPS塑料,适配宽温;整体经精密冲压装配,尺寸精度±0.1mm,接口配合一致。

四、安装与兼容性说明

  1. 安装适配:插件结构无需特殊工具,引脚插入PCB孔位焊接即可;弯头设计灵活适配板上不同方向信号路径,减少布线复杂度;
  2. 接口兼容:符合BNC标准,可直接与同规格公头连接器/线缆组件配合,兼容RG58、RG174等主流射频线缆;
  3. PCB适配:接口直径与引脚间距符合标准PCB规范,无需定制板孔,降低开发成本。

五、可靠性与品质保障

金航标针对该产品完成多重可靠性测试:

  1. 环境可靠性:通过-65℃低温存储(24h)、+165℃高温存储(24h)、-55℃~+155℃温度循环(50次)测试,性能无衰减;盐雾测试(48h)后接触件无腐蚀;
  2. 信号可靠性:3GHz下插入损耗≤0.2dB,回波损耗≥20dB,保证低损耗传输;
  3. 品质认证:符合RoHS标准,通过ISO9001认证,广泛应用于通信、军工等对品质要求严格的领域。

KH-BNC50-3511以高适配性、高可靠性成为板级射频连接的实用选择,满足不同行业的紧凑布局与信号稳定需求。

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
