Description: Transmitter & Receiver NRF905 Wireless 433MHz Transceiver & Receiver Module With Antenna
The Nordic nRF905 is a highly integrated, low power, multiband RF transceiver IC for the 433/868/915MHz ISM (Industrial, Scientific and Medical) band. With an integrated +10dBm PA and sensitivity of -100dBm, the nRF905 is an ideal solution for applications requiring longer-range. The Shock Burst™ hardware protocol accelerator offloads time critical protocol functions from the application microcontroller enabling the implementation of advanced and robust wireless connectivity with low cost 3rd-party microcontrollers.
In summary, the nRF905 integrates a complete 433/868/915MHz ISM RF transceiver, RF synthesizer, and baseband logic, including the Shock Burst™ hardware protocol accelerator supporting a high-speed SPI interface for the application controller. No external loop filter, resonators, or VCO varactor diodes are required, only a low cost crystal, matching circuitry, and antenna.
100% brand new and high quality
Tri-band transceiver operating frequency for international ISM band 433/868/915 MHz GMSK modulation, anti-interference capability.
Especially for industrial control applications using DSS + PLL frequency synthesizer technology, excellent frequency stability, high sensitivity.
To achieve -100dBm operation of low voltage (2.7 V), low power consumption, expects only 1uA dBm maximum transmission power of + 10 with multiple channels (up to more than 170).
To meet the requirements of low-power devices, in particular, to meet the needs of multi-channel work on special occasions, the work rate of up to 76.8 Kbps.
External components of at least (10), the basic need for debugging. Low transmission power and high sensitivity of design reception.
The use of the necessary license to apply for use over distances up to 1000m open and the specific use of the environment and the parameters of components.
