Amplitude Shift Keying (ASK). The spreading modulation scheme is a
Bi-Phase modulation where each bit has a 13-bit Barker series.
Below are the key features of the transceiver module:
2.4-GHz unlicensed ISM band operation
1 Mbps data rate
Sample 3 line digital interface
Low power consumption
+2 dBm typical peak output transmission power
–80 dBm typical sensitivity
Typical standby current of 2.6
m
A
Compiles with FCC regulation
Wide range operating voltage (2.7 V–3.6 V)
Direct Sequence Spread Spectrum (DSSS) 11 dB processing gain
Short signal acquisition time (1.2
m
s)
The transceiver has a fully digital serial I/O interface providing a simple
3-line interface. Tx/Rx is for controlling of the transceiver work in transmit
or receive mode. Act is used for switching the transceiver between
working mode and sleep mode. Data IO is the data transfer channel.
The transceiver chipset includes three chips.
RFW24 — An RFIC performs all of the timing, amplifying,
switching, transmitting, and receiving functions.
RFW488C — A 4-pin SAW correlator, which is used as a direct
sequence spread spectrum spreading and de-spreading element.
RFW488R — A 1-port SAW resonator, which serves as the
system oscillation source.

module, please refer to the data sheet about the RFW102 from
