Advances High Performance ASK and
FSK Narrow-Band Transceiver for
27−1050 MHz Range
OVERVIEW
AX5043 is a true single chip low-power CMOS
transceiver for narrow band applications. A fully integrated
VCO supports carrier frequencies in the 433 MHz,
868 MHz and 915 MHz ISM band. An external VCO
inductor enables carrier frequencies from 27 MHz to
1050 MHz. The on-chip transceiver consists of a fully
integrated RF front-end with modulator, and demodulator.
Base band data processing is implemented in an advanced
and flexible communication controller that enables user
friendly communication via the SPI interface.
An on-chip low power oscillator as well as Wake-on-radio
enable very low power standby applications. The AX5043
is also available with the AX8052F100 microcontroller in
a single integrated circuit as the AX8052F143. Figure 1
shows the block diagram of the AX5043.
