LFCN-1450+ 产品概述

一、产品简介

LFCN-1450+ 为 Mini-Circuits 提供的一款表面贴装低通滤波器,专为射频(RF)系统的信号调节与带外抑制设计。该器件在50Ω系统中工作,截断频率为1.825 GHz,典型插入损耗约为1 dB,工作温度范围宽(-55℃ ~ +100℃),并符合RoHS 环保要求,适合要求小型化、可靠性高的射频前端和测试系统应用。

二、主要技术特性

  • 滤波类型:低通(Low Pass)
  • 截止频率:1.825 GHz
  • 额定阻抗:50 Ω
  • 插入损耗:约 1 dB(典型)
  • 工作温度:-55℃ ~ +100℃
  • 封装形式:表面贴装(SURF MT)
  • 环保合规:RoHS

这些参数保证了在通带内较低的损耗和在截止以上频段的有效抑制,便于维护系统增益和降低互调及带外干扰。

三、典型应用场景

  • 无线通信发射/接收前端的带外滤波与谐波抑制
  • 射频信号链的反射与干扰控制(如放大器、混频器前端)
  • 测试与测量设备中的前置滤波器与带宽限定
  • 卫星、雷达及无线基站等对频谱整洁性有要求的系统
  • 本地振荡器、频谱分析与信号调理电路

四、封装与热、环境性能

LFCN-1450+ 采用紧凑表面贴装体积,有利于高密度PCB布局。其宽温度工作范围适配工业级应用。推荐在布局时注意充分接地与热路径,使用过孔环绕地平面有助于抑制寄生辐射与改善功率散热。

五、使用建议与注意事项

  • 保持输入/输出端的50Ω阻抗匹配,减小反射损耗与驻波比影响。
  • PCB布局时短走线、良好接地和必要的屏蔽可以提高滤波效果。
  • 遵循器件制造商的焊接与回流规范,避免超出推荐的热循环以保障可靠性。
  • 避免长期施加超出器件额定功率或高反射条件下工作,以防性能退化。
  • 在系统设计中预留足够的带外余量,确保滤波器在实际环境和温度漂移下仍能满足要求。

六、总结

LFCN-1450+ 为需要兼顾体积、插入损耗与带外抑制的射频系统提供了实用的低通滤波解决方案。其50Ω兼容性、约1 dB 的低插损及宽温度工作范围,使其在通信前端、测试设备及其他高频应用中具有良好的适配性与可靠性。对于追求系统性能与尺寸优化的工程设计,LFCN-1450+ 是一个值得考虑的元件选项。

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
