DEA162690LT-5051B1 产品概述
一、主要特点
DEA162690LT-5051B1 是 TDK 推出的高性能低通射频滤波器，中心截止频率设计为 1.6815 GHz，面向紧凑型射频前端应用。该器件在 50 Ω 传输线上表现优异，具有极低的通带纹波（0.07 dB）和极小的插入损耗（0.5 dB），适合对信号完整性要求较高的系统。工作温度范围为 -40 ℃ 至 +85 ℃，满足工业级温度规范。
二、典型电性能
- 滤波类型：低通（Low-pass）
- 截止/设计频率：1.6815 GHz
- 系统阻抗：50 Ω
- 通带纹波：0.07 dB（典型）
- 插入损耗：0.5 dB（典型）
- 工作温度：-40 ℃ ～ +85 ℃
这些参数保证了在所述频段下最小的通带衰减与极佳的幅度平坦性，从而有效抑制带外干扰并保持接收/发射链路的线性与灵敏度。
三、封装与机械特性
该器件采用 SMD-4P 封装，尺寸为 1.6 × 0.8 mm，适合高密度贴装与空间受限的模块化设计。小尺寸有利于在移动设备、无线模块及紧凑型基站单元中实现体积最小化，同时降低寄生效应对性能的影响。
四、典型应用场景
- 移动通信射频前端与收发器滤波
- 无线接入设备、基站与小型基站单元（Small Cell）
- IoT 无线模块与终端
- 测试测量设备的信号整形与带外抑制
- 任何需在 ~1.7 GHz 附近保持低损耗和低纹波的射频系统
五、工程与封装使用建议
- PCB 布局：建议采用 50 Ω 微带或带状线设计，滤波器输入/输出端到器件的过孔与走线尽量短，周围应有连续地平面地（GND）并做地穿孔（via）环绕以降低辐射与串扰。
- 焊接工艺：支持标准回流焊工艺。为保证可靠焊接与热循环稳定性，建议遵循元件供应商的回流温度曲线与焊接工艺规范。
- 机械防护：避免在回流后对器件施加过大机械应力，贴装过程中注意不要挤压封装边缘。
- 温度与环境：在极端环境或严苛振动条件下，请在工程评估阶段进行可靠性测试以验证长期性能。
六、采购与技术支持
DEA162690LT-5051B1 由 TDK 生产，可通过正规分销渠道采购。建议在设计初期索取器件数据手册与典型 S-参数文件（S21、S11），以便在仿真工具中进行外形与系统级匹配验证。如需高阶定制或批量可靠性数据，可联系 TDK 或授权代理获取更多工程支持。
总结：DEA162690LT-5051B1 以其低插入损耗、极低通带纹波和小型 SMD 封装，适用于对信号质量要求苛刻且空间受限的射频设计，是 1.6815 GHz 附近滤波需求的优选方案。

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.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
