NRF24L01 PA LNA 2.4GHz Transceiver Module

The NRF24L01 PA LNA is a 2.4GHz wireless transceiver module that pairs the Nordic nRF24L01+ radio IC with an integrated power amplifier (PA) and low-noise amplifier (LNA), extending both transmit range and receive sensitivity. It operates across the global ISM band from 2.400GHz to 2.4835GHz, supports GFSK modulation, and delivers data rates of 250kbps, 1Mbps, or 2Mbps. The onboard PA provides up to +20dBm output power, while the LNA improves receiver sensitivity to -104dBm at 250kbps, enabling reliable links at distances of up to 1100 meters under line-of-sight conditions. Communication with the host microcontroller uses a standard SPI interface with 3.3V–5V tolerant logic pins, and the module accepts a supply voltage of 1.9V to 3.6V (3.3V recommended). Its compact 27mm × 12mm ceramic-antenna footprint and 1.27mm pin pitch make this NRF24L01 PA LNA module easy to integrate into existing boards, breadboards, and Arduino projects. With a wide operating temperature range of -40°C to +85°C, this GFSK transceiver module is suited to wireless sensor networks, remote controls, telemetry, and IoT endpoints that require dependable long-range 2.4GHz communication.
