2.4G Transceiver Module with nRF24L01P RF chip & RFX2401C Power Amplifier
DL-24NPA is an industrial grade 2.4G RF transceiver module with high power (100mW), it has high speed (max. air rate up to 2Mbps) with high stability, which adopts NORDIC original nRF24L01P RF chip and RFX2401C power amplifier chip with LNA built in. Receiving sensitivity is improved by 10dBm, and it works in 2.4Ghz ~ 2.5Ghz ISM band.
The output interface of this module is IPEX, which is super small in size and conveniently embedded in the product. The module has the transmitting power of 20dBm, very good spectrum characteristic, small harmonic, and small crosstalk between channels. The high frequency material is originally from Murata, while the crystal is high precision and low temperature drift industrial-grade.
