Tổng Quan Sản Phẩm
NRF21540-QDAA-R7 is a nRF21540 RF front-end module suitable for Bluetooth Low Energy and IEEE 802.15.4 range extension. The features include a configurable gain power amplifier (PA) in the transmit path (TX) and low noise amplifier (LNA) in the receive path (RX). Single-ended operation on both TRX and ANT1/2 ports is supported and requires only three external components (for single antenna operation) for the RF path. The device is controlled through a set of input pins and/or through the SPI interface, by writing to internal control registers. The two antenna ports enable applications using antenna diversity and can be selected using pin ANT-SEL. The device features highly configurable gain in Transmit state, enabling the application to implement adaptive gain control algorithms. Typical applications include smart Home applications, industrial and factory automation, asset tracking, advanced CE remote controls, sports and fitness, toys, medical, and beacons.
