Features: NRF24L01P+PA+LNA is a high-power and high-sensitivity wireless transceiver module specially developed for ultra-long-distance data transmission. The wireless module works in the license-free 2.4G ISM band and can be used in point-to-point applications or in a star network. The core of the wireless module is the latest high-performance wireless data transmission chip NRF24L01+, adding high-power PA and LNA chips, RF switch, band-pass filter, etc to form a professional full-bidirectional RF power amplifier, which greatly expands the effective communication distance. In the RF part, a large number of optimized matching and debugging are performed to maximize the transmission efficiency and minimize the harmonics, so that the radio frequency interference of wireless module to the external device is minimized, and it is not easily interfered by other devices. Greatly improve the stability of the work. The wireless module is highly integrated and has a size of only 41mm*15.5mm. It is easy to embed in any space-constrained product. Customers only need to add one MCU to control the wireless module through the SPI port to complete the design of ultra-long-range wireless data transmission system. There is no need to worry about the development of the RF part, and the R&D expenditure and the development cycle are greatly reduced.
