MAX2870ETJ+T 产品概述

一、概述

MAX2870ETJ+T 是一款超宽带锁相环(PLL)频率合成器,内置压控振荡器(VCO),能够在整数N与分数N模式下工作。该器件与外部参考振荡器与环路滤波器配合使用时,可作为高性能频率合成核心,覆盖23.5MHz 至 6.0GHz 的输出频率范围,适用于多种通用射频系统与测试场景。

二、主要技术参数

  • 工作频率:23.5MHz ~ 6.0GHz(通过多个集成VCO实现 3000MHz ~ 6000MHz 的超宽覆盖)
  • 工作电压:3.0V ~ 3.6V
  • 工作温度:-40℃ ~ +85℃
  • 输出分频器:可编程,分频比 1 ~ 128
  • 输出驱动:双差分输出驱动器,可独立编程,输出功率范围 -4dBm ~ +5dBm
  • 锁定检测:集成锁检测功能
  • 封装:TQFN-32 (5×5)

三、功能亮点

  • 超宽频率覆盖:多个集成VCO组合,实现从低频到 6GHz 的连续合成能力,减少外部VCO需求。
  • 高可编程性:支持整数/分数N工作模式以及可编程输出分频,便于在不同系统架构中灵活配置。
  • 性能优化:在参考外部晶振与环路滤波器匹配时,可获得优异的相位噪声与杂散抑制性能,适合对相位噪声敏感的通信与测量应用。
  • 输出驱动能力强:双差分输出可独立调节功率,利于直驱下游射频级或经放大器/滤波器的系统集成。
  • 实用的工作范围与工业级温度覆盖,适合商业与工业应用。

四、典型应用

  • 无线基站本振与上变频/下变频 LO 源
  • 测试与测量仪器的可编程频率源
  • 宽带射频收发系统、微波通信链路
  • 合成器模块、频谱分析与信号发生器

五、封装与使用建议

器件以 TQFN-32(5×5)封装提供,便于表面贴装与紧凑布局。为发挥最佳性能,建议配合低相噪参考振荡器、合理设计的环路滤波器与射频版图(良好接地、匹配与隔离)。在输出功率与相位噪声之间存在权衡,应根据系统需求在分频与输出驱动设置上进行调优。

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
