Product Description
Nordic Semiconductor NRF905 RF Transceiver IC is a specialized Low IF/ISM transceiver designed for use in the 433MHz, 868MHz, and 915MHz ISM frequency bands. Packaged in a compact 32-Pin QFN form factor measuring 5mm by 5mm by 0.85mm, this device integrates an RF Synthesizer and baseband logic with SPI interface support.
The NRF905 supports GFSK modulation and delivers a data rate of 50kbps with a receiver sensitivity of -100dBm for a bit error rate of 0.1%, making it highly suitable for long-range wireless data transmission in industrial, commercial, and consumer applications.
Operating within a voltage range of 1.9V to 3.6V DC and an extended temperature range of -40°C to +85°C, it ensures robust performance under varying environmental conditions. Its ShockBurst™ hardware protocol efficiently manages packet preamble and CRC, enabling reduced host processing.
This transceiver is ideal for wireless data communication, alarm and security systems, home automation, remote control devices, surveillance, automotive telemetry, keyless entry systems, toys, and local Internet of Things (IoT) communication setups.
The device is manufactured in the Philippines following industry standards, though it does not carry specific certifications or automotive standards. Operates on 433, 868, and 915 MHz ISM bands with channel spacing of 100kHz and 200kHz.
Offers up to +10dBm RF power output for strong transmission signals. Supports Listen-Before-Transmit (LBT) functionality for wireless coexistence. Surface-mount QFN package with 32 pins facilitates compact PCB designs. Communication via a serial SPI interface enables easy integration with microcontrollers.
This product enhances wireless connectivity solutions for industrial, laboratory, and commercial applications. Browse related RF ICs and transceiver modules on EnvMart for advanced communication components.
