LR1121IMLTRT — Semtech LR1121 LoRa Connect 双频射频收发器产品概述

一、产品简介

LR1121IMLTRT 是 Semtech 推出的 LR1121 LoRa Connect 双频无线收发器,集成了低功耗射频前端与基带控制接口,面向物联网终端及网关应用。器件支持 150 MHz ~ 960 MHz 的亚吉赫频段以及 1.9 GHz~2.1 GHz、2.4 GHz~2.5 GHz 的高频段,适用于多种区域和应用场景的 LoRa 通信需求。

二、主要性能参数

  • 频率范围:150 MHz ~ 960 MHz;1.9 GHz ~ 2.1 GHz;2.4 GHz ~ 2.5 GHz
  • 接口类型:SPI(控制与数据交互)
  • 工作电压:1.8 V ~ 3.7 V
  • 输出功率:13 dBm(典型)
  • 数据速率:101.5 kbps
  • 发射电流:约 26 mA
  • 接收电流:约 7.8 mA
  • 接收灵敏度:-108 dBm(典型)
  • 工作温度:-40 ℃ ~ +85 ℃
  • 封装:QFN-32-EP (5x5)
  • 类型:射频收发器(Transceiver)

三、应用场景

LR1121 适合对射频覆盖和功耗有严格要求的物联网设备,包括但不限于:

  • 低功耗广域网(LPWAN)设备与 LoRa 终端
  • 多频段网关与中继节点
  • 智慧城市、智能计量、农业与工业无线传感器网络
    其双频支持使设备可在受限频谱或需跨频段部署时灵活选择最优链路。

四、优势与设计要点

  • 低功耗:发射与接收电流均处于低水平,利于电池供电设备长寿命运行。
  • 多频段覆盖:同时支持亚吉赫与高频段,为全球化部署和共存干扰管理提供便利。
  • 容易集成:标准 SPI 接口便于与 MCU 连接,QFN-32-EP 紧凑封装适合空间受限的终端设计。
  • 设计建议:射频段需配合合适的匹配网络、带通滤波和专用天线;电源侧应做好去耦与滤波,SPI 时序与 IO 电平需与主控兼容(1.8–3.7 V)。

五、封装与可靠性

器件采用 QFN-32-EP(5x5) 封装,适合自动贴装与回流焊工艺。工作温度覆盖工业级范围(-40 ℃ 至 +85 ℃),满足多数户外与工业环境的长期可靠性需求。

结语:LR1121IMLTRT 为需要多频段、低功耗和 LoRa 连接能力的物联网产品提供了高集成度的射频解决方案。在系统设计时,应结合天线、滤波及电源管理做全面优化,以发挥其最佳射频与功耗性能。

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
