2.4G Transceiver Module with nRF24L01P RF chip & RFX2401C Power Amplifier
DL-24NPA is a 2.4GHz, 100mW, high speed (the highest air rate can reach 2Mbps), high stability, industrial-grade wireless transceiver integrated data transmission module. The module uses NORDIC original nRF24L01P radio frequency chip and RFX2401C power amplifier chip, built-in LNA, receiving sensitivity increased by 10dBm, working in the 2.4GHz~2.5GHz ISM band.
The output interface of the module is IPEX, which is ultra-small in size and convenient to be embedded in the product. The module has a transmission power of 20dBm, the spectrum characteristics are very good, the harmonics are small and the crosstalk between channels is small, the high-frequency materials are original from Murata, and the crystals use high-precision low-temperature drift industrial-grade devices.
