LFCN-1000+ 产品概述

一、产品概述

LFCN-1000+ 是 Mini‑Circuits 推出的一款表面贴装型低通滤波器,针对 50Ω 射频系统的信号调节与带外抑制设计。器件采用 1206(3216 公制)封装,RoHS 合规,工作温度范围宽(-55℃ 至 +100℃),适用于商用、工业及部分军工级应用环境。

二、主要规格

  • 滤波器类型:低通(Low Pass)
  • 截止频率:约 1.3 GHz
  • 系统阻抗:50 Ω
  • 插入损耗:典型 1 dB(通带内)
  • 工作温度:-55℃ ~ +100℃
  • 封装:1206 表贴(3216 metric)
  • 合规性:RoHS

三、性能与特性

LFCN-1000+ 在通带内提供低插入损耗,能有效保持信号幅度与相位完整性;在截止频率以上实现带外抑制,削弱高次谐波与干扰。紧凑的 SMT 封装利于高密度线路板布局,同时具备良好的热稳定性,适合长期在较大温度范围内工作。Mini‑Circuits 的设计与制造工艺保证了器件在射频带宽内的重复性和可靠性。

四、典型应用

  • 射频前端:LNA 之前或之后的带外抑制与带通整形
  • 发射链路:抑制谐波与带外辐射,满足发射带谱要求
  • 接收链路:降低带外噪声与干扰,提高接收灵敏度
  • 混频与变频模块:抑制高频成分,改善信号纯度
  • 测试测量设备与通信基站、无线设备、卫星与导航系统等

五、封装与装配建议

1206 表贴封装适配常规 SMT 生产线,便于回流焊工艺集成。为获得最佳电气性能与可靠性,建议按制造商提供的布局与焊盘推荐进行 PCB 设计,并采用标准的回流焊曲线。器件应避免在受潮条件下长时间暴露,存储与装配遵循常规电子元件防潮与静电防护规范。

六、使用注意事项

  • 推荐在 50Ω 系统中使用,以确保匹配与最小反射损耗。
  • 在关键应用场合(如高功率发射)评估功率承受能力与温升;如有高功率或特殊环境需求,应参照制造商详细规格或咨询技术支持。
  • 遵照 Mini‑Circuits 的安装与回流焊指南,避免超出其热与机械应力极限。

七、总结

LFCN-1000+ 是一款针对 50Ω 射频系统设计的高性价比低通滤波器,兼顾低插入损耗与带外抑制性能。其小型 SMT 封装、宽温特性及 RoHS 合规性,使其适用于通信、测试、航天与工业电子等多种应用场景。如需更详细的 S参数、最大输入功率或 PCB 推荐封装图,请参考 Mini‑Circuits 技术文档或联系供应商获取原厂资料。

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
