CL-PCB028-1, RB001 User Manual

General

Power supply: The radio module uses one LDO N1 to provide power for transceiver and RF FEM.

Transmit: The CC2520 features a Direct Conversion Transceiver operating in the 2.4 GHz band. During the

transmit stage, the CPU of main board send data to the CC2520 through the SPI interface. When the

CC2520 get emission instruction from CPU, it will go into transmit mode and modulate data up to radio

band, after the modulation stage the modulated RF signal is sent to the PA of CC2592, the PA fulfils power

amplification, finally the RF signal radiate out through selected antenna.

Receive: During the receive stage, the CC2520 get a receipt instruction from CPU, it will go into receive

mode. The RF signal is received from selected antenna, it go into LNA of CC2592, the LNA amplifies the

received RF signal, after that the RF signal go into the CC2520, the demodulator of CC2520 is responsible

for retrieving data from the received signal, after demodulated the data will send to CPU through SPI

interface.

Frequency range: 2405-2480MHz

Modulation: O-QPSK

Max EIRP: 22.88dBm

Antenna port: Antenna 1 & 2 share the same RF port and are switched by a RF switch.
