Kinghelm KH-3216-A27 Chip蓝牙贴片天线产品概述

KH-3216-A27是金航标(Kinghelm)针对2.4GHz蓝牙通信场景推出的小型化陶瓷贴片天线,专为智能穿戴、智能家居、物联网终端等紧凑设备设计,凭借高增益、宽温适应性与超小尺寸,成为蓝牙射频模块的优选配套方案。

一、产品定位与典型应用场景

KH-3216-A27聚焦**“小空间内实现稳定蓝牙连接”**的核心需求,重点覆盖三大应用领域:

  1. 智能穿戴设备:智能手环、蓝牙耳机、智能手表的内置天线(适配1206封装,可嵌入PCB高密度区域);
  2. 智能家居终端:温湿度传感器、门窗传感器、智能门锁的无线模块(小尺寸不影响设备外观);
  3. 工业物联网终端:资产追踪标签、无线传感器节点、小型手持终端(宽温适应性满足户外/工业环境)。

二、核心性能参数深度解析

该天线针对蓝牙2.4GHz频段定向优化,关键参数匹配无线通信需求:

  • 频段覆盖:中心频率2.45GHz,带宽100MHz(2.42.5GHz),完全覆盖蓝牙2.4022.480GHz全工作范围,避免信号溢出或频段缺失;
  • 增益表现:5.54dBi(陶瓷贴片天线中属于高增益级别),较同尺寸3dBi天线提升约15%,室内环境下可将蓝牙传输距离延长至10~15米,复杂障碍物场景下抗干扰能力更强;
  • 阻抗与驻波比:标准50Ω射频阻抗,与nRF52、CC2541等主流蓝牙模块完美匹配,无需额外阻抗匹配电路;驻波比≤2,反射损耗≤-10dB,信号传输效率达90%以上,减少模块发热与信号丢失;
  • 极化方式:垂直极化(陶瓷天线常见极化),适配蓝牙设备的常规安装角度,无需复杂极化调整。

三、封装与尺寸设计优势

KH-3216-A27采用1206标准贴片封装,尺寸仅为3.2mm(长)×1.6mm(宽)×0.6mm(高),具备三大设计优势:

  1. 空间利用率高:与1206封装贴片电阻电容尺寸一致,可直接嵌入PCB布局(甚至0.6mm厚度的柔性PCB),满足蓝牙耳机、智能手环等超小型设备的空间限制;
  2. 自动化贴装兼容:贴片封装适配SMT生产线,可实现高速批量贴装,降低生产工艺复杂度;
  3. 陶瓷材料特性:采用高密度陶瓷介质,相比传统鞭状天线体积缩小80%,且抗机械冲击、抗老化性能更优。

四、环境适应性与可靠性保障

针对不同场景的环境需求,KH-3216-A27具备宽温与耐候性:

  • 宽温工作范围:-40℃+85℃,覆盖工业级(-4085℃)与消费级(-20~60℃)温度需求,可稳定工作于冬季户外、夏季车内等极端环境;
  • 耐候性:陶瓷材料化学稳定性强,抗盐雾(符合GB/T 2423.17标准)、抗潮湿,适合沿海地区、高湿度环境的长期使用;
  • 可靠性测试:通过金航标内部高低温循环(-4085℃循环50次)、振动测试(102000Hz,加速度2g),确保批量产品性能一致性。

五、品牌与品质保障

金航标(Kinghelm)作为国内射频天线领域的专业厂商,KH-3216-A27具备可靠的品质背书:

  • 研发实力:专注无线通信天线10余年,拥有自主陶瓷天线研发实验室,针对蓝牙频段进行定向优化;
  • 批量一致性:采用高精度陶瓷成型工艺,每批次产品参数偏差≤±0.1dBi,满足工业级产品的一致性要求;
  • 技术支持:提供天线布局参考(如PCB接地设计、天线周围净空区要求),帮助客户快速实现稳定连接。

KH-3216-A27以“小尺寸、高增益、宽温适配”为核心竞争力,解决了小型蓝牙设备的信号传输痛点,是智能穿戴、智能家居等领域的高性价比天线方案。

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
