金航标KH-3216-A35陶瓷天线产品概述

一、产品定位与核心优势

KH-3216-A35是金航标(Kinghelm)LA系列中的小体积SMD片式陶瓷天线,专为紧凑空间的无线通信设备设计。其核心价值集中在「小尺寸+宽兼容+高稳定」:采用1206标准贴片封装,体积仅3.2×1.6×1.2mm,可轻松集成到手机、可穿戴、IoT模块等微型设备中;同时兼容2.4GHz频段下多类无线协议,信号覆盖稳定,能满足中低端到主流无线设备的通信需求,无需额外复杂匹配电路,降低设计成本。

二、基础性能参数详解

该天线的关键参数经过场景化优化,适配主流无线应用:

  • 中心频率:2.45GHz,精准匹配2.4GHz ISM(工业、科学、医疗)免授权频段,是WiFi、蓝牙等协议的核心工作频点,无需额外频偏调整;
  • 带宽:100MHz(覆盖2.4~2.5GHz),可支持多信道并行传输(如WiFi 802.11n的20/40MHz信道),降低同频干扰风险;
  • 增益:5.19dBi,高于同类小尺寸陶瓷天线平均水平(通常3~4dBi),能有效提升信号发射/接收距离,减少弱信号区域的通信中断;
  • 阻抗:50Ω,与绝大多数射频电路的标准阻抗匹配,无需额外阻抗匹配网络,简化PCB设计流程;
  • 驻波比(VSWR):≤2,驻波比越小表示天线与电路匹配度越高,信号反射损耗越低,通信质量更稳定(如语音通话无杂音、数据传输无丢包)。

三、封装与物理特性

KH-3216-A35采用1206贴片封装(行业通用尺寸:长3.2mm×宽1.6mm×高1.2mm),适合自动化表面贴装工艺(SMT),生产效率高且一致性好,可直接集成到主流PCB板中。
天线本体为微波多层陶瓷材质,具有以下特性:

  • 机械强度高:不易因碰撞、振动出现性能衰减,适合便携设备的日常使用;
  • 抗老化性强:陶瓷材质耐温、耐湿,长期使用无明显性能漂移;
  • 无金属外露:避免电磁干扰,同时降低氧化风险。

四、典型应用场景

因体积小、兼容多协议,KH-3216-A35广泛覆盖以下场景:

  1. 移动终端:手机、平板、智能手表的WiFi/蓝牙天线,或作为手机多频天线的补充单元(如FM+蓝牙二合一);
  2. IoT设备:智能家居(智能灯泡、温湿度传感器)、可穿戴(手环、无线耳机)、工业IoT(小型数据采集模块)的无线通信天线;
  3. 蓝牙/WiFi模块:路由器、蓝牙音箱、无线游戏手柄等设备的内置天线;
  4. 传统通信终端:PHS(小灵通)终端的天线单元;
  5. 音频设备:带FM功能的收音机、智能音箱的FM天线(多频兼容设计)。

五、环境适应性说明

该天线的工作温度范围为**-40℃~+85℃**,覆盖工业级温度标准,可适应复杂环境:

  • 低温场景:北方户外、冷库设备等;
  • 高温场景:车载中控台、工业控制柜等;
  • 湿度耐受:能承受一定的环境湿度变化(如沿海地区、室内潮湿环境),长期工作无性能衰减。

此外,其SMD封装可兼容无铅回流焊工艺,符合RoHS环保标准,适合出口产品的设计要求。

KH-3216-A35凭借小体积、高兼容、稳定可靠的特性,成为无线通信设备(尤其是微型、便携类)的高性价比天线选择,可满足多数中低端到主流设备的通信需求。

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
