DPX105950DT-6112A2 产品概述

一、产品简介

TDK 型号 DPX105950DT-6112A2 是一款多层陶瓷双工器(Multilayer Diplexer),用于在单一射频链路上实现 2.4 GHz ~ 2.5 GHz 与 4.9 GHz ~ 5.95 GHz 两个频带的隔离与分配。器件采用表面贴装封装(SMD-4P,尺寸 1.0 × 0.5 mm,对应 0402 / 1005 公制)并设计用于直接安装在 PCB 上,适合空间受限的消费类与通信终端设备。

二、主要电气参数

  • 类型:双工器(Diplexer)
  • 低频带:2.4 GHz ~ 2.5 GHz
  • 高频带:4.9 GHz ~ 5.95 GHz
  • 低频带衰减(隔离/最小-最大):23.00 dB ~ 29.00 dB
  • 高频带衰减(隔离/最小-最大):32.00 dB ~ 41.00 dB
  • 回波损耗(低/高频带):10.0 dB / 10.0 dB
  • 封装/外壳:0402(1005 公制),4 PCB 引脚,SMD-4P

    注:上述参数为典型规格,实际应用请以 TDK 官方规格书为准。

三、典型应用

  • 无线局域网(WLAN)与双频 Wi‑Fi(2.4 GHz 与 5 GHz)射频前端分配
  • 无线接入点、路由器、网关与终端设备的天线复用/分路
  • MIMO 模块、小型基站与物联网网关中的频带隔离与滤波
  • 需要体积小、线路板空间受限的便携式或嵌入式设备

四、封装与安装

该器件为表面贴装型,SMD-4P(1.0 × 0.5 mm,对应 0402/1005 公制)。设计时应遵循 PCB 布局推荐:为保证性能,保持器件附近的地平面完整,避免在器件下方或近旁放置高通量信号走线或过孔;推荐在封装引脚周围预留合理焊盘和回流温度曲线,按制造商回流焊工艺规范进行焊接。

五、主要特点与优势

  • 紧凑尺寸:0402 级别封装,节省 PCB 空间,适合小型化设计。
  • 高隔离:低频与高频带之间提供较高的衰减值(最小 23 dB,最高可达 41 dB),有效抑制互干扰。
  • 适用双频 Wi‑Fi:覆盖 2.4 GHz 与 5 GHz 常用频段,可直接用于双频天线分配。
  • 可直接表贴安装,便于自动化生产。

六、使用建议与注意事项

  • 阻抗匹配:器件设计基于 50 Ω 系统,系统其他部分应保持 50 Ω 匹配以达到标称回波损耗和隔离性能。
  • 热与功率处理:如需大功率传输或在高温环境下长期工作,请参考 TDK 规格书的功率与温漂限制。
  • PCB 布局:为获得最佳隔离与回波损耗,避免在器件附近放置不必要的金属挡板或大型铜箔,并遵循厂商的布线与接地建议。
  • 验证与测试:在设计验证阶段建议做实际天线与射频路径的 S 参数测量,以确认在整机环境下的实际表现。

七、结语

DPX105950DT-6112A2 以其高隔离、小体积与 SMD 可装配性,适合要求双频分离、空间受限的无线终端与基础设施设备。为确保设计一次通过,请在最终设计前查阅并遵循 TDK 官方数据手册和安装建议,并在样机阶段完成射频测试验证。

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
