The BK5812 is a high data rate FSK/GFSK transceiver operating in the worldwide ISM frequency band at 2.400–2.500 GHz.

The BK2480 series includes BK2481, BK2482 and BK2483.

BK5813 is a high data rate FSK/GFSK transceiver operating in the frequency band from 4.9G to 5.85GHz. The embedded packet processing engine enables its full operation with a very simple MCU as a radio system. Burst mode transmission is up to 6 Mbps air data rate make it suitable for applications requiring ultra low power consumption and high data rate. Auto re-transmission and auto acknowledge give reliable link without any MCU interference.
