TFSC06053925-2111B2X 产品概述

一、产品简介

TFSC06053925-2111B2X 是 TDK 推出的薄膜(Thin‑Film)方向耦合器,针对双频无线通信应用优化设计。器件采用 SMD-4P 封装(标注尺寸 0.7 × 0.5 mm),实体尺寸仅约 0.65 × 0.5 mm,极小体积便于高密度封装与移动终端集成。该器件覆盖 2.4 GHz2.5 GHz 与 4.9 GHz5.85 GHz 两段常用无线频段,具有稳定的耦合系数和低损耗特性,适合射频前端的功率分配、监测与隔离等功能。

二、主要性能参数

  • 工作频率:2.4 GHz ~ 2.5 GHz;4.9 GHz ~ 5.85 GHz(双频段)
  • 耦合系数:20.5 dB(典型)
  • 插入损耗(Through):0.32 dB(典型)
  • 回波损耗(Return Loss):17.69 dB / 20.3 dB(典型,依据端口不同)
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 尺寸:长度约 0.65 mm,宽度 0.5 mm;封装 SMD-4P(0.7 × 0.5 mm 标称)

以上指标体现了器件在常见无线链路中对信号的低消耗与良好匹配能力,可减少系统总体噪声和功率损失。

三、产品特点与优势

  • 极小尺寸:0.7 × 0.5 mm 的 SMD 封装适合紧凑型 PCB 布局,利于手机、无线模块与 IoT 终端的小型化设计。
  • 双频覆盖:同时支持 2.4 GHz 与 5 GHz 频段,适配 Wi‑Fi、Bluetooth、某些专网和无线回传应用,减少器件种类与库存压力。
  • 低插入损耗:典型 0.32 dB,能最大限度降低信号传输损耗,提升系统效率与链路预算。
  • 稳定耦合:20.5 dB 耦合系数,适合做功率取样与监测,便于射频前端的功率控制与校准。
  • 良好端口匹配:回波损耗 17.69 dB / 20.3 dB 水平,意味着较低反射,便于后级放大器与天线的稳定工作。
  • 宽温度工作区:-40 ℃ 到 +85 ℃ 满足工业级与消费级产品的环境要求。

四、典型应用场景

  • WLAN / Wi‑Fi(2.4 GHz 与 5 GHz)终端与接入点
  • 蓝牙与混合无线模块的功率监测与方向性分配
  • 无线基站小型化射频前端、射频开关矩阵中的信号取样
  • 射频测试与测量设备中的耦合与校准电路
  • IoT 与智能家居设备的天线分配与分路监测

五、封装与装配建议

  • 封装类型:SMD-4P,推荐按照 TDK 提供的参考 PCB 尺寸与焊盘布局进行设计,以保证焊接可靠性与电性能一致性。
  • 焊接工艺:支持常规无铅回流焊。建议遵循制造商的回流温度曲线与湿度管控要求,避免超限热应力或潮湿引发的器件失效。
  • 布局注意事项:尽量缩短射频走线长度,保持耦合器附近阻抗连续,避免在近旁放置大面积金属或高频电源平面导致辐射或寄生耦合。
  • 机械应力:由于器件体积小,应在 PCB 装配与测试过程中避免过大弯曲或压迫,防止封装破损。

六、可靠性与环境适应

TFSC06053925-2111B2X 工作温度范围覆盖 -40 ℃ 至 +85 ℃,适应移动设备、户外终端与工业环境的温度变化。薄膜工艺保证了长期电性能稳定性和较高的一致性,适合量产与批量一致性要求高的系统设计。

七、选型与注意事项

  • 若系统对耦合精度或隔离度有严格要求,建议参考 TDK 的完整数据手册获取频率依赖曲线与端口隔离(isolation)、方向性(directivity)等详细参数。
  • 设计时考虑功率承受能力与最大输入电平;在高功率应用中应评估器件热耗散与可能的非线性效应。
  • 采购与样片验证时,请向 TDK 或授权分销商索取器件的最新规范书和 EDA 封装文件,以确保与 PCB 制造流程匹配。

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
