Measurement results show that EFR32 MG1 complies with EN300 328 category1 blocking requirements with good margin in 802.15.4 OQPSK DSSS mode (ZigBee PHY).
The blocking test has been performed as per chapter 22.214.171.124.1.
RFIC: EFR32 MG1
Board: PCB4252A 2.4 GHz
SDK: Flex 126.96.36.199
RAIL: RAIL 188.8.131.52
App: RAILTest 1.4.2
This command set configures the part to the 802.15.4 OQPSK DSSS ZigBee PHY.
Payload length is 16 bytes.
ZigBee packet: Agilent E4432B
Blocker: HP 8665B
Conducted PER curve
1% PER Sensitivity: -97.5 dBm
10% PER Sensitivity: -98.5 dBm
Conducted Blocking at various channels
Desired signal power level is set to (10% PER sensitivity + 6 dB) = -92.5 dBm.
f_Channel11: 2405 MHz
f_Channel18: 2440 MHz
f_Channel26: 2480 MHz
How should I connect the pins which are not intended to be used on EFR32?
