BFR193L3E6327XTMA1 产品概述

一、产品简介

BFR193L3E6327XTMA1 是英飞凌(Infineon)推出的一款 NPN 射频晶体管,采用表面贴装封装 TSLP-3-1。该器件专为 VHF/UHF 及移动通信频段的低噪声放大和前端增益级设计,可在紧凑的 SMT 方案中提供高增益与低噪声性能。典型应用为 900MHz 到 1.8GHz 范围内的接收前端、低噪声放大器(LNA)、中低功率射频增益级以及移动通信和无线基础设施设备中的增益块。

二、主要性能特点

  • 增益:典型 12.5 dB ~ 19 dB(随频率变化),适合需要较高电压增益的射频电路。
  • 噪声系数:典型 1.0 dB ~ 1.6 dB(在 900MHz ~ 1.8GHz),适合低噪声接收器前端。
  • 峰值频率(fT):约 8 GHz,支持 GHz 级工作频率并能在目标频段提供良好放大特性。
  • 直流电流放大率 hFE:在 Ic=30 mA、VCE=8 V 条件下 hFE 最小 70,便于偏置设计与增益估算。
  • 电流与功率:最大集电极电流 Ic = 80 mA,最大耗散功率约 580 mW。
  • 耐压与温度:集—射极击穿电压 V(BR)CEO ≈ 12 V;结温 TJ 最大 150°C。
  • 封装:小型表面贴装 TSLP-3-1,适合高密度 PCB 布局与自动化贴装。

三、典型应用场景

  • 移动通信基站与收发器的低噪声前端(900 MHz ~ 1.8 GHz)。
  • 无线收发模块、ISM 频段放大器与中小功率射频链路。
  • GPS/定位接收器、无线基础设施前端放大器(作为 LNA 或二级增益级)。
  • 各类便携或基站级射频放大器,要求小体积、低噪声与可靠偏置特性场合。

四、电气与热设计要点(参考)

  • 建议工作偏置:通常在保证不超过 Ic(max)=80 mA 与 VCE < V(BR)CEO(约12 V) 的前提下选取合适工作点。常见低噪声偏置点:Ic≈20–40 mA、VCE≈5–8 V,可在噪声与线性之间取得平衡(在 Ic=30 mA、VCE=8 V 时 hFE≥70)。
  • 功率耗散:最大功率耗散约 580 mW,PCB 散热设计需保证结温低于 TJ(max)=150°C。实际可用耗散受 PCB 散热和环境限制影响,必要时通过大铜面积或热 vias 提升散热能力。
  • 电压限制:VCE 不要接近或超过 12 V,以免触发击穿。器件应具备良好浪涌与瞬态保护(尤其在开机或欠压情况下)。

五、封装与安装建议

  • 封装为 TSLP-3-1,适合常规无铅回流焊流程。请按厂商回流曲线与焊膏数据作工艺限定(避免超温导致器件应力)。
  • SMT 安装时注意焊盘设计与过孔布局,保证散热路径畅通。关键点包括:输入/输出信号线尽量短且阻抗匹配,地线大面积铜箔并配合足够的接地 vias。
  • ESD 与湿敏:射频晶体管对静电和湿度敏感,储存与生产过程应严格遵守 ESD 防护与湿敏等级要求。

六、射频电路设计建议

  • 低噪声工作:为获得最低噪声系数,应在设计中优化输入匹配以实现最小噪声系数点(源阻抗匹配),并采用低损耗的阻容元件与短引线。
  • 输出匹配与线性:在寻求高增益时,注意输出匹配对线性与功率的影响。必要时可使用小的发射极偏置电阻做退化以提高稳定性与线性。
  • 电源去耦与偏置:射频供电端应使用宽带旁路电容和低 ESL 的去耦网络,偏置网络应隔离射频并避免寄生振荡。

综上,BFR193L3E6327XTMA1 是一款面向 900MHz–1.8GHz 等通信频段的高增益、低噪声 NPN 射频晶体管,适合用于紧凑 SMT 射频前端设计。在设计中应重点关注偏置选择、输入匹配与 PCB 散热,以发挥其低噪声与高增益优势。若需最终电气特性曲线、S 参数或封装尺寸,请参阅英飞凌官方 datasheet 以获得完整参数与应用电路建议。

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
