GENERAL DESCRIPTION
          BK2401/BK2421 is an FSK/GFSK transceiver operating in the ISM frequency band at 2.402 – 2.4835 GHz.. The embedded packet processing engine enables its full operation with a very simple MCU as a radio system. Burst mode transmission and up to 1 Mbps/2 Mbps air data rate make it suitable for applications requiring ultra low power consumption. Auto re-transmission and auto acknowledge ensures a reliable wireless link
