RFANT5220110A2T 产品概述

一、产品简介

RFANT5220110A2T 是华新科(Walsin)推出的一款贴片式陶瓷天线,针对2.4GHz频段优化设计,适用于蓝牙、Wi‑Fi、物联网和短距无线通信模块。产品小巧、外形稳定,便于自动贴装,型号标识为 RF ANT 2.4GHZ CHIP SOLDER SMD,封装尺寸为 SMD, 2×5.2mm,适合高密度 PCB 布局。

二、主要参数

  • 天线类型:陶瓷天线
  • 中心频率:2.4 GHz
  • 带宽:990 MHz(宽带设计,覆盖2.4GHz相关子频段)
  • 增益:2 dBi
  • 阻抗:50 Ω
  • 最大功率:3 W
  • 驻波比(VSWR):2(典型上限)
  • 工作温度:-40℃ 至 +85℃
  • 外形尺寸:直径 φD 1.55 mm,长度 5.2 mm,宽度 2 mm,厚度/高度 1.1 mm
  • 封装:SMD,尺寸 2×5.2 mm
  • 品牌:华新科(Walsin)

三、性能特点

  • 陶瓷材料提供稳定的电气特性与良好的温度稳定性,适合长时间工作环境。
  • 2 dBi 的增益在板级天线中表现均衡,兼顾覆盖范围与方向性。
  • 宽带设计(990 MHz)使得天线在2.4GHz附近具有较好的频率容忍度,便于工程调整和频段覆盖。
  • SMD 封装支持回流焊制造流程,利于自动化生产与批量装配。

四、典型应用

  • 蓝牙(BLE)、Wi‑Fi(2.4GHz)终端与网关
  • IoT设备、智能家居模块、遥控与传感节点
  • 无线模块、低功耗广域设备与便携式电子产品

五、封装与安装建议

  • 天线设计为50 Ω系统匹配,PCB布局时建议保持馈线连续性并接入适当的接地参考。
  • 在天线附近保持足够的“空白区”(无大金属器件或密集走线)以降低阻抗干扰并优化辐射效率。
  • 采用推荐的焊盘尺寸及回流焊工艺,控制焊接温度曲线以避免热应力损伤陶瓷体。
  • 最大输入功率3W,确保系统发射功率及功率放大器输出在该限值内以免损坏天线。

六、可靠性与注意事项

  • 工作温度范围 -40℃ 至 +85℃,适应一般工业级环境。
  • 驻波比上限为2,实际系统中建议进行天线调谐和S参数测试以确保良好匹配。
  • 使用前建议在目标PCB上做实物测试(S11、辐射方向图)以验证实际性能。

Product sourcing intelligence

Model, package, availability, and BOM fit reviewed before quotation.

WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.

Electronic component model and package intelligence review on an ESD-safe inspection bench

Model & package intelligence

Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.

BOM matching and alternative component comparison workstation with protected IC samples

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
