HMC433ETR 超高频4分频计数器产品概述

一、产品基本信息

HMC433ETR是亚德诺半导体(ADI)推出的固定4分频超高频计数器,属于ADI高速射频分频器系列,采用SOT-23-6小型表面贴装封装。该器件专为射频、微波及高速数字系统的频率分频需求设计,继承了ADI在射频器件领域的高可靠性与高性能优势,适配宽电压范围与工业级温区,是紧凑型高频系统的理想选择。

二、核心性能参数

参数项 规格值 说明 分频逻辑 固定4分频 输入信号分频后输出频率为1/4输入频率 工作电压范围 2.7V ~ 3.3V 宽电压适配低功耗与标准电源系统 最高计数速率 8.5GHz 支持超宽带高频信号分频 工作温度范围 -40℃ ~ +85℃ 工业级温区,适应户外、车载等恶劣环境 封装类型 SOT-23-6 超小型表面贴装(2.9mm×2.6mm),节省PCB空间 典型功耗 ~10mW(3V供电下) 低功耗设计,适合电池供电设备

三、关键特性优势

  1. 超小封装集成:SOT-23-6封装大幅减少PCB占用面积,适配便携式、紧凑型设备(如手持测试仪器、无人机通信模块);
  2. 宽频高速性能:支持输入频率覆盖10MHz至8.5GHz,满足5G、卫星通信等高频系统的分频需求;
  3. 低功耗与单电源:2.7~3.3V单电源供电,无需额外电源转换电路,简化系统设计;
  4. 高信号质量:低相位噪声与高线性度,分频过程中保持输入信号完整性,避免失真;
  5. 工业级可靠性:通过严格的温度、湿度及机械可靠性测试,适应极端环境。

四、引脚功能配置

HMC433ETR采用SOT-23-6封装,引脚定义(顶部视角,引脚1为标识点顺时针排列):

引脚编号 名称 功能说明 1 Vcc 电源输入(需并联0.1μF陶瓷电容至地) 2 GND 接地(需可靠连接系统地平面) 3 RF IN 射频输入(单端,50Ω阻抗匹配) 4 RF OUT 分频输出(单端,50Ω阻抗匹配,4分频结果) 5 NC 空脚(无连接,避免悬空引入干扰) 6 NC 空脚(无连接,避免悬空引入干扰)

五、典型应用领域

HMC433ETR的高频性能与小型化优势,使其广泛应用于:

  • 无线通信:5G/4G基站本振分频、射频前端频率合成;
  • 测试测量:频谱分析仪、信号发生器的频率扩展模块;
  • 雷达系统:相控阵雷达时钟分频、信号下变频;
  • 卫星通信:低轨卫星载荷射频链路分频;
  • 便携式设备:手持测试仪器、无人机通信模块的高频分频。

六、电路设计要点

为保证稳定工作,需注意以下细节:

  1. 电源滤波:Vcc引脚并联0.1μF陶瓷电容(靠近引脚)至地,抑制电源噪声;
  2. 阻抗匹配:输入/输出需匹配50Ω阻抗(微带线或匹配网络实现);
  3. 接地设计:GND引脚直接连接系统地平面,减少接地阻抗;
  4. 空脚处理:NC引脚无需连接,避免悬空干扰;
  5. 散热考虑:虽功耗低,但需避免封装周围热源,保证温度在工作范围内。

HMC433ETR凭借高性能、小型化与高可靠性,成为高频系统分频设计的优选器件,覆盖通信、测试、雷达等多领域应用。

Electronic component sourcing availability dashboard with ESD-protected samples

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
