金航标KH-3216-H0209贴片天线产品概述

KH-3216-H0209是金航标(Kinghelm)针对2.4GHz ISM频段小体积无线设备推出的高性能贴片天线,兼顾射频稳定性与小型化设计,适配自动化SMT生产,广泛应用于智能穿戴、工业物联网等场景。

一、产品定位与核心价值

该天线聚焦小型化无线设备的痛点,核心价值体现在三个维度:

  • 尺寸与性能平衡:用3.23×1.66×0.45mm的紧凑体积,实现稳定的2.4GHz频段覆盖;
  • 系统兼容性:匹配通用50Ω射频端口,无需额外复杂匹配电路,降低设计成本;
  • 环境可靠性:工业级温区范围,满足户外/工业场景的极端温度需求。

二、核心射频性能参数

KH-3216-H0209的射频性能精准适配2.4GHz主流无线协议,关键参数及实际意义如下:

  1. 中心频率:2.45GHz
    覆盖蓝牙(2.4022.480GHz)、Wi-Fi 2.4G(2.4122.484GHz)的核心工作频段,无需频段切换即可支持多协议通信;
  2. 带宽:120MHz
    足够覆盖蓝牙全频段(79个信道)及Wi-Fi 2.4G主要信道(1~14),避免频段偏移导致的信号衰减;
  3. 增益:1.71dBi
    在贴片天线中属于中等偏上水平,可提升10~30米近距离通信的信号强度,减少误码率;
  4. 阻抗:50Ω
    匹配绝大多数射频模块的端口阻抗,直接焊接即可使用,无需额外匹配网络;
  5. 最大工作功率:4W
    覆盖低功耗BLE(典型10mW)到中等功率设备(如2.4G遥控),避免过载损坏。

三、物理与封装特性

该天线采用1206封装(英制尺寸,对应公制3.2×1.6mm),与实际尺寸高度契合,具备以下优势:

  • 超小体积:仅0.45mm高度,可集成到智能手环、贴片传感器等超薄设备中,不影响产品外观;
  • 贴片式设计:支持SMT自动化贴装,生产效率高,适合大规模量产;
  • 无外露结构:表面平整,避免运输/使用中的物理碰撞损坏,可靠性更高。

四、环境适应性设计

针对不同场景的环境要求,KH-3216-H0209做了针对性优化:

  • 宽温区工作:-40℃+110℃,覆盖工业级(-4085℃)及部分车载场景(-40~105℃),可在户外低温、工业高温环境下稳定工作;
  • 抗干扰优化:通过辐射模式设计,减少周围金属部件(如PCB地平面)的干扰,提升信号稳定性。

五、典型应用领域

KH-3216-H0209适配多种2.4GHz无线设备,典型应用包括:

  1. 智能穿戴:智能手环、手表的蓝牙/Wi-Fi天线,满足小体积与稳定通信需求;
  2. 工业物联网:温度、湿度传感器的无线传输天线,适配工业现场宽温环境;
  3. BLE模块:智能家居、健康监测设备的BLE模块集成天线,提升通信距离;
  4. 小型无线设备:2.4G遥控、无线门铃、智能门锁的天线,兼顾成本与性能。

六、选型与使用注意事项

为确保天线性能稳定,使用时需注意:

  1. 阻抗匹配:必须连接50Ω射频端口,匹配误差建议≤±5Ω,避免反射损耗;
  2. 安装环境:天线周围10mm范围内避免大面积金属(如PCB地平面),否则会降低辐射效率;
  3. 功率限制:工作功率不超过4W,避免长时间过载导致性能衰减;
  4. 温区要求:严禁在-40℃以下或+110℃以上环境中工作,否则可能损坏天线。

该天线以高性价比、小体积、宽温适应性成为2.4GHz频段小型无线设备的优选方案,可满足多数消费电子与工业场景的通信需求。

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
