General Description
The BK4815N is a half duplex TDD FM transceiver operating from 124 MHz to 560 MHz band for worldwide personal radio.
Besides speech communication, theBK4815N on-chip FSK data modemsupports F2D and F1W emission to be used in both FRS and DPMR band for text
message and GPS information exchange. The BK4815N is a complete, small form factor solution optimized for low-power,low-cost,
and highly integrated mobile and portable consumer electronic devices, requiring only a few external decoupling capacitors and an external inductor for input matching.
