ADT1-1+ 产品概述

ADT1-1+ 是 Mini-Circuits 提供的一款宽带小型信号变压器(RF/XFMR),适用于从低频到 UHF 较低段的信号耦合与阻抗变换。器件设计为表面贴装(SURF MOUNT)、符合 RoHS 要求,具有低幅度不平衡、良好相位一致性和较高回波损耗,适合对相位/幅度匹配有较高要求的差分/单端转换、平衡馈入、隔离及阻抗匹配应用。

一、主要参数一览

  • 频率范围:150 kHz ~ 400 MHz(宽带工作)
  • 阻抗比(不平衡/平衡):50 Ω : 50 Ω(1:1 平衡/不平衡变换)
  • 相位差(最大):5°
  • 幅度差(最大):0.1 dB
  • 回波损耗(最小):22 dB
  • 工作温度:-20 ℃ ~ +85 ℃
  • 封装形式:表面贴装(封装型号未知)
  • 符合性:RoHS 兼容
  • 品牌:Mini-Circuits

二、性能特点与优势

  • 宽频带覆盖:150 kHz 起到 400 MHz,覆盖音频上端到射频低频段,适应多种系统的宽带需求。
  • 高保真平衡/不平衡转换:50Ω:50Ω 的 1:1 设计,适于将单端信号转换为平衡输出(或反向),保持系统阻抗匹配,减少反射和失配损耗。
  • 极小幅度/相位不平衡:幅度差 ≤ 0.1 dB, 相位差 ≤ 5°,在差分信号处理、IQ 解析或通道匹配时能显著降低失真与共模干扰。
  • 良好回波损耗:≥ 22 dB(最小值),意味着在工作频段内输入/输出端具有较低的反射,系统传输效率高且易于保障阻抗匹配。
  • 表面贴装与 RoHS:适合现代 SMT 生产工艺和环保要求,方便批量化组装和自动化贴片。

三、参数含义与设计影响

  • 频率范围:表示器件在该范围内能保持额定性能。低频端 150 kHz 说明该器件适合处理较低频率的交流或基带信号;高频端 400 MHz 使其在诸如 VHF 以下的通信、测试与混频电路中可用。
  • 阻抗比 50Ω:50Ω:为 1:1 变压器/平衡器,便于在 50Ω 系统中做单端与差分的互换,不需要额外匹配网络。
  • 相位/幅度不平衡:对差分通信、混频器 LO/IF 平衡、A/D 驱动等精密应用至关重要。极小的不平衡意味着两路输出在幅度与相位上高度一致,可减小失真与偶次/奇次失配产生的误差。
  • 回波损耗:数值越大表示反射越小,≥22 dB 表明在大部分应用中可认为与 50Ω 系统良好匹配,简化系统设计。

四、典型应用场景

  • 差分/单端信号转换(balun):将单端 RF 信号转换为差分形式以驱动差分放大器或 ADC。
  • 通信前端:用于收发链路中的阻抗耦合、隔离与相位平衡,例如无线基站、天线馈线接口的宽带平衡处理。
  • 测试与测量仪器:高精度示波器输入、网络分析仪前端的差分耦合与失配最小化。
  • 混频器与合成器:LO 信号分配与差分驱动,减少相位和幅度不平衡对转换增益的影响。
  • 工业与医疗电子:对噪声、共模抑制和差分匹配有要求的传感器接口与数据采集前端。

五、封装与安装建议

  • 表面贴装设计减少引线电感与寄生,提高高频性能。虽未提供具体封装型号,但常见 Mini-Circuits 表贴变压器体积小,应注意 PCB 布局与地平面完整性。
  • 推荐做法:
    • 在变压器的两侧与地之间保留良好回流路径,尽量缩短输入/输出之间的走线长度以减少寄生电感/电容。
    • 在差分输出处尽量保持走线长度一致,并在需要时使用差分微带线或阻抗控制层。
    • 控制焊接热循环,遵循制造商的回流温度曲线(典型 RoHS 表贴焊接工艺)。
    • 考虑 ESD 保护与静电敏感器件的防护措施。

六、选型提示与替代方案

  • 若系统频率或带宽超出 150 kHz~400 MHz,需选择更宽带或专用低频/高频型号。
  • 对于需要电气隔离比(如 1:4、1:2 等)或不同阻抗配比(75Ω 系统等),可选用相应比率的 Mini-Circuits 变压器或定制方案。
  • 需要更小相位/幅度不平衡或更高回波损耗时,可参考 Mini-Circuits 更高性能系列或差分匹配网络结合使用。

总结:ADT1-1+ 是一款面向宽带、对相位与幅度一致性有严格要求场合的 1:1 表贴信号变压器。凭借 150 kHz–400 MHz 的覆盖、优良的相位与幅度平衡及较高的回波损耗,它适用于差分/单端转换、平衡驱动、阻抗匹配与高保真信号传输场合,在无线通信、测试仪器与数据采集等领域具有广泛应用价值。若需更详细的机械尺寸、引脚定义或典型电路图,请参考 Mini-Circuits 的产品数据表(datasheet)。

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.
