LFCN-320+ 低通滤波器产品概述

一、产品核心定位与应用场景

LFCN-320+是Mini-Circuits推出的表面贴装式低通滤波器,专为射频/微波系统中的信号纯净度优化设计——核心作用是抑制高于截止频率的杂散信号(如谐波、电磁噪声),同时保留有用频段内的信号强度。该产品采用1206(3216 metric)紧凑封装,适配高密度PCB布局,且符合RoHS环保标准,适用于对信号质量、环境适应性要求较高的多领域场景。

二、关键性能参数解析

1. 截止频率与滤波特性

截止频率为460MHz(低通特性):允许频率低于460MHz的有用信号低衰减通过,对高于该频率的干扰信号实现有效抑制,是实现信号滤波的核心指标。

2. 阻抗与匹配性

特征阻抗为50Ω:匹配射频系统常用的标准阻抗,可直接兼容绝大多数射频器件(如放大器、混频器、天线),无需额外阻抗匹配电路,简化系统设计流程。

3. 插入损耗

有用频段内插入损耗**≤1dB**:信号衰减量控制在极小范围,避免因滤波导致的功率损失,保证系统信号强度。

4. 环境适应性

工作温度范围为**-55℃~+100℃**:覆盖工业级宽温环境,可稳定工作于极端低温(如航空航天、极地设备)或高温(如车载发动机舱、工业炉旁)场景,抗环境干扰能力强。

5. 封装与合规性

  • 封装规格:1206(3216 metric),尺寸约3.2mm×1.6mm×1.0mm,小体积适合高密度PCB设计;
  • 环保认证:符合RoHS指令,不含铅、镉等有害元素,满足绿色设计需求。

三、封装与制造工艺特点

LFCN-320+采用1206表面贴装封装,具有以下工艺优势:

  1. 贴装兼容性:适配标准SMT贴片机,支持高速批量生产,降低制造成本;
  2. 可靠性:Mini-Circuits成熟制造工艺确保产品一致性,宽温范围内性能稳定,抗振动、抗冲击能力符合工业级标准;
  3. 空间效率:小体积设计可在有限PCB面积内集成更多功能模块,适合小型化射频设备(如便携式测试仪、无线模块)。

四、典型应用领域

该产品因性能均衡、环境适应性强,广泛应用于以下场景:

  1. 射频通信系统:400MHz频段的无线数据传输(如UHF RFID读写器、无线传感器网络)、短距离无线通信设备,滤除高频杂波提升通信稳定性;
  2. 测试测量仪器:信号发生器、频谱分析仪、网络分析仪的前端滤波模块,确保输出信号纯度,提高测试精度;
  3. 工业射频控制:工业无线遥控器、自动化生产线的射频通信链路,抗工业环境中的高频干扰(如电机噪声、电磁辐射);
  4. 车载射频系统:车载无线通信(如4G/LTE车机、蓝牙模块)、车载雷达辅助滤波,适应车载宽温(-40℃~+85℃)环境;
  5. 医疗设备:对信号纯度要求较高的医疗射频设备(如低强度射频治疗设备),滤除干扰信号保证设备性能稳定。

五、产品优势总结

LFCN-320+的核心优势体现在:

  • 性能与体积平衡:低插入损耗+小体积,兼顾信号质量与设计空间;
  • 宽温可靠性:-55℃~+100℃工作范围,适应极端环境;
  • 设计兼容性:50Ω标准阻抗+1206封装,易集成到各类射频系统;
  • 环保与品牌保障:RoHS合规+Mini-Circuits行业认可,降低选型风险。

该产品是射频系统中实现信号滤波、抗干扰的高性价比选择,可满足多领域对信号纯净度与环境适应性的需求。

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
