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.
