SX1276 Overview

The LoRa® long-range modem in the SX1276 transceivers delivers ultra-long-range spread spectrum communication and high interference immunity while consuming minimal current.

SX1276 can reach a sensitivity of over -148 dBm using Semtech's unique LoRa modulation technology with a low-cost crystal and bill of materials. The combination of high sensitivity and an included +20 dBm power amplifier results in an industry-leading link budget, making it ideal for any application needing range or durability.

LoRa also outperforms classic modulation approaches in terms of blocking and selectivity, resolving the traditional design compromise between range, interference immunity, and energy consumption.

For systems like as WMBus and IEEE802.15.4g, these devices additionally enable high-performance (G)FSK modes. The SX1276 outperforms rival devices in terms of phase noise, selectivity, receiver linearity, and IIP3 while consuming much less current.

    Current - Transmitting is a parameter used to describe the maximum amount of electrical current that an electronic component can handle while in the transmitting mode. This parameter is crucial for components such as transistors, diodes, and integrated circuits that are involved in transmitting signals or power within a circuit. Exceeding the specified current transmitting rating can lead to overheating, component failure, or even damage to the entire circuit. Designers and engineers must carefully consider this parameter when selecting components to ensure the reliability and performance of the electronic system.

  • Modulation

    In electronic components, modulation refers to the process of varying one or more properties of a periodic waveform, known as the carrier signal, in order to encode information. This modulation technique is commonly used in communication systems to transmit data efficiently over long distances. By modulating the carrier signal, information such as audio, video, or data can be embedded onto the signal for transmission and then demodulated at the receiving end to retrieve the original information. There are various types of modulation techniques, including amplitude modulation (AM), frequency modulation (FM), and phase modulation (PM), each with its own advantages and applications in different communication systems.

    FSK, GFSK, GMSK, MSK, OOK
  • Sensitivity (dBm)

    Sensitivity (dBm) is a parameter used to measure the minimum input power level required for an electronic component or device to operate effectively. It is typically expressed in decibels relative to one milliwatt (dBm), which is a common unit of power measurement in the field of electronics. A higher sensitivity value indicates that the component can detect weaker input signals, making it more responsive and capable of functioning in low-power conditions. Sensitivity is an important specification for devices like receivers, sensors, and transducers, as it directly impacts their ability to detect and process signals accurately. Manufacturers often provide sensitivity ratings to help users understand the performance capabilities of the component in different operating conditions.

    -148 dBm
  • RoHS Status

    RoHS means “Restriction of Certain Hazardous Substances” in the “Hazardous Substances Directive” in electrical and electronic equipment.

    RoHS Compliant
  • Lead Free

    Lead Free is a term used to describe electronic components that do not contain lead as part of their composition. Lead is a toxic material that can have harmful effects on human health and the environment, so the electronics industry has been moving towards lead-free components to reduce these risks. Lead-free components are typically made using alternative materials such as silver, copper, and tin. Manufacturers must comply with regulations such as the Restriction of Hazardous Substances (RoHS) directive to ensure that their products are lead-free and environmentally friendly.
