Wireless IC - RF298

Product Specification

The RF298 is a low-cost, highly integrated 2.4-GHz wireless transceiver chip. Works in the 2.400~2.483GHz world Universal ISM band. On-chip integrated transmitter, receiver, frequency integrator, GFSK modem. RF298 transmits GFSK signal, with the maximum transmission power up to 10 dBm, and more than 120 meters in open areas. The standard application is 8 dBm. The receiver adopts a low and medium frequency structure, and the reception sensitivity can reach-86 dBm. The chip highly integrates the peripheral devices into the inside of the chip, integrating the RF front-end matching circuit, 22K resistance, crystal load capacitance, VDD capacitor, etc. At present, the peripheral devices of the chip can only need two capacitances and one crystal vibration.

-Emission mode (0 dBm) The operating current is 16 mA

-Receive the mode operating current of 14 mA

-The resting current was 1.5 uA

high integration density

-The peripheral element needs only two capacitors and one crystal vibration

low cost
