RFANT5220110A0T 产品概述

一、产品简介

RFANT5220110A0T 是华新科(Walsin)出品的一款陶瓷芯片天线,工作在 2.45GHz ISM 频段,适用于蓝牙、Wi‑Fi(2.4GHz)、Zigbee 及各类低功耗物联网终端。天线体积小巧,仅 5.2mm × 2.0mm × 1.15mm,便于贴装于 PCB 边缘或紧凑型模块中。

二、主要电气性能

  • 中心频率:2.45 GHz
  • 增益:2 dBi(峰值方向性增益,典型值)
  • 阻抗:50 Ω(射频输入口)
  • 最大输入功率:5 W
  • 驻波比(VSWR):≤2(典型工作条件下)
  • 工作温度:-40℃~+85℃

三、机械与封装信息

  • 外形尺寸:5.2 mm × 2.0 mm × 1.15 mm
  • 封装:未知(客户须向供应商确认具体包装形式与贴片编码)
  • 品牌:华新科(Walsin)

四、典型应用场景

  • 2.4GHz 蓝牙低能耗(BLE)模块与终端
  • 2.4GHz Wi‑Fi 嵌入式设备(短距离无线连接)
  • Zigbee / Thread 等智能家居、传感器网络节点
  • 小型无线模块、可穿戴设备、遥控器与工业无线控制

五、安装与 PCB 布局建议

  • 建议将天线放置于 PCB 边缘或角落,尽量靠近板外无遮挡空间,有利于辐射效率。
  • 下方应保留合理的空白或限制金属/地铜箔,以避免近场干扰与增益下降;具体保留尺寸请与天线厂商确认并做板级调试。
  • 尽量使用 50Ω 射频传输线连接,并在天线馈点预留匹配网络空间(可放置贴片电感/电容)以优化驻波比与带宽。
  • 避免金属外壳或金属件直接覆盖天线区域,如必须存在,应进行屏蔽开口或调整天线位置并重新测量。

六、使用注意事项

  • 由于封装与实际板级环境会影响谐振频率和带宽,建议在目标 PCB 上进行实际调谐与天线参数验证(S11、辐射图)。
  • 最大输入功率为 5W,超过该值可能导致天线损坏或性能退化。
  • 包装形式(封装)信息未提供,量产前应确认供应商的包装与贴装兼容性。

如需板级参考设计、匹配网络建议或测试数据(S参数、辐射图),建议联系华新科技术支持或提供具体 PCB 板样进行评估与调试。

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
