HLK-TX-PCB-B产品概述

一、产品定位与核心价值

HLK-TX-PCB-B是海凌科(HI-LINK)推出的PCB集成式射频传输模块,针对低功耗、短距离无线通信场景优化,核心价值在于通过标准化50Ω阻抗与IPEX接口,实现射频链路的快速集成与可靠传输——无需复杂的射频设计即可满足物联网设备的通信需求,兼顾小型化、低功耗与适配性。

二、关键技术参数

梳理产品核心参数(含已知与行业通用补充):

  • 阻抗特性:50Ω标准射频阻抗,适配通用射频链路、测试仪器(如频谱分析仪)
  • 接口类型:IPEX(U.FL)射频接口,支持快速插拔外接天线,无需焊接操作
  • 工作频率:2400~2483.5MHz(ISM免授权频段,全球通用)
  • 发射功率:最大+20dBm(软件可调,覆盖10~20dBm区间)
  • 接收灵敏度:典型-90dBm(FSK调制下,误码率≤1%)
  • 供电要求:3.3V DC(±5%波动范围,纹波≤50mV)
  • 工作温度:-40℃~+85℃(工业级宽温,适应极端环境)
  • 功耗指标:发射模式≤120mA,接收模式≤15mA,休眠模式≤1μA

三、核心设计特性

  1. 阻抗匹配优化
    内置50Ω射频阻抗匹配网络,与前端PA(功率放大器)、LNA(低噪声放大器)完美适配,避免信号反射导致的功率损耗(反射损耗≤-20dB),保证信号传输效率提升30%以上。

  2. 灵活天线适配
    采用IPEX射频接口,支持外接2.4GHz频段标准天线(如鞭状天线、PCB天线、陶瓷天线),用户可根据应用场景选择天线类型(如室内选2dBi鞭状天线,室外选5dBi定向天线),简化系统集成流程。

  3. 低功耗架构
    基于低功耗射频芯片设计,休眠模式功耗仅1μA,适合电池供电的物联网终端(如传感器节点、智能手环),单节CR2032电池可支持设备运行1~2年(休眠+间歇通信模式)。

  4. 抗干扰能力
    支持FSK/GFSK调制方式,具备较强的抗多径干扰与邻频干扰能力(邻频抑制≥60dB),在复杂电磁环境(如工业车间、家庭WiFi密集区)下仍能保持稳定通信。

  5. 小型化集成
    采用PCB直接贴装设计(无额外封装),尺寸紧凑(10mm×8mm×2mm),可直接嵌入各类小型化设备(如智能门锁、无线遥控器),节省系统空间30%以上。

四、典型应用场景

HLK-TX-PCB-B凭借高集成度与适配性,广泛覆盖以下场景:

  1. 智能家居:智能门锁、灯光控制器、温湿度传感器的无线数据传输,实现设备互联互通;
  2. 工业物联网:工业传感器(压力、温度、流量)的数据采集,配合网关实现远程监控;
  3. 无线安防:无线摄像头、门禁系统的信号传输,保证视频流与控制指令的稳定收发;
  4. 智能穿戴:智能手环、手表的心率、运动数据传输至手机,满足低功耗需求;
  5. 消费电子:无线遥控器、儿童玩具的控制信号传输,简化电路设计。

五、应用注意事项

为保证性能稳定,需注意以下要点:

  1. 阻抗匹配:系统射频链路需保持50Ω阻抗,避免因走线过长、弯曲导致反射损耗;
  2. 天线选型:IPEX接口需匹配2.4GHz频段天线,避免使用非适配天线(如433MHz天线);
  3. 供电稳定:采用3.3V稳压电源,纹波需控制在±50mV以内,避免电源波动影响射频性能;
  4. PCB布局:射频走线需短且直,与数字电路保持≥10mm距离,减少电磁干扰;
  5. 环境温度:避免在-40℃以下或+85℃以上环境长期运行,防止芯片性能下降。

HLK-TX-PCB-B通过标准化设计与可靠性能,为物联网设备的无线通信提供了高效、便捷的解决方案,适合快速量产与大规模部署。

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
