DESCRIPTION
DRF1101F10 is a type of low cost RF front-end transceiver module based on CC1101 from Texas Instruments. It keeps all the advantages of RFIC CC1101 but simplifies the RF circuit design. DRF1101F10 module consists of RFIC CC1101, thin SMD crystal and antenna matching circuit. The antenna port is well matched to standard 50 Ohm impedance. Users don’t need to spend time in RF circuit design and choose suitable antennas for different applications. DORJI also provides SMA connector and high gain antenna for longer communication distance. DRF1101F10 operates at 1.8~3.6V with extra low standby current which makes it suitable for battery powered-up applications.
