LFCN-1500+ 产品概述
一、产品简介
LFCN-1500+ 是 Mini-Circuits 提供的一款小型表面贴装低通滤波器，适配 50Ω 射频系统，标称截止频率 1.825 GHz。器件采用 SMD-4P 结构，外形尺寸仅 3.2 × 1.6 mm，专为空间受限的射频前端、信号整形与杂散抑制应用设计，符合 RoHS 要求，工作温度范围 -55℃ 至 +100℃。
二、主要性能特点
- 滤波类型：低通（Low Pass）
- 截止频率：1.825 GHz
- 系统阻抗：50 Ω
- 插入损耗：约 1 dB（典型/最大视具体测试条件）
- 工作温度：-55℃ ~ +100℃
- 封装：SMD-4P，3.2 × 1.6 mm，便于自动贴装与回流焊接
- 环境与合规：RoHS 合规，适用于商业与工业级应用
三、典型应用场景
- 移动通信前端（如 1.8 GHz 频段收发链路的通带整形与镜像抑制）
- 无线基站、小型天线阵列及便携式终端的带外干扰抑制
- 测试与测量系统中的带通前级、滤波与抗混叠处理
- 射频信号处理、放大器保护及收发器之间的频率选择
四、封装与机械特性
LFCN-1500+ 的 SMD-4P 封装尺寸为 3.2 × 1.6 mm，电气引脚布局适合标准 SMT 工艺。其小尺寸有利于高密度布局和多通道滤波器阵列的实现。建议参考厂商提供的尺寸与焊盘图，以保证可靠的焊接强度与一致的电气性能。
五、安装与布局建议
- 保持输入、输出到滤波器的连接线最短，避免不必要的弯折与延长导致寄生感抗变化。
- 使用 50Ω 的传输线（微带或带状线）并确保良好接地，滤波器底部及周围区域建议增加过孔接地以降低共模效应。
- 遵循制造商的回流焊温度曲线与焊盘设计，避免超出温度极限以维持器件可靠性。
- 在高功率或敏感测量场合，建议进行实板测试以确认插入损耗与频率响应满足系统需求。
六、采购与合规
LFCN-1500+ 由 Mini-Circuits 提供，适合需要体积小、性能稳定的 50Ω 低通滤波需求。采购时请确认具体的频率响应曲线、插入损耗测试条件及批次数据表，以便在系统集成时获得可重复的性能表现。
七、注意事项
- 在未取得完整数据表前，不建议在关键路径中替代使用；如需精确的通带平坦度、阻带衰减等参数，应参考厂商官方数据手册与样品测试结果。
- 使用前确认工作温度边界和长期温度循环对频率特性的影响，确保在目标环境下的稳定性。
如需更详细的电气参数、S-参数文件或推荐 PCB 焊盘与回流曲线，可联系供应商或参考 Mini-Circuits 官方技术资料。

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.
