1 General Description
BK4800/10 is a half duplex TDD FM transceiver operating in the 400 MHz licen free band for worldwide personal radio rvice. The transceiver integrated high performance PLL, ADC, DAC, and advanced digital signal processing capability on a single chip. The digital low-IF image rejection architecture enables it to work with a very simple MCU as a two way radio communication system. On-chip flexible and preci continuous and discrete tone generator and detector enable a cure link and digital signaling.
BK4800/10 on-chip FSK data modem supports F2D and F1W emission to be ud in both FRS and DPMR band for text message and GPS information exchange besides speech communication.
BK4800 and BK4810 have no difference in current stage.
