General Description
The BK4819 is a half duplex TDD FM
transceiver operating within 18 MHz ~ 660
MHz, 840 MHz ~1300 MHz band range for
worldwide personal radio. Besides speech
communication, the BK4819 on-chip FSK
data modem supports F2D and F1W
emission to be used in both FRS and
DPMR band for text message and GPS
information exchange.
The BK4829 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.
