4 Electrical Characteristics
Note:
• The current consumption measurements are taken with a 3.3 V supply at 25 °C of ambient temperature at the RF
port. All transmitters’ measurements are based on a 50% duty cycle.
• The current consumption figures for in RX mode are for cases when the peripherals are disabled and the CPU idle.

2412 ~ 2484 MHz
Wi-Fi wireless standard IEEE 802.11b/g/n
Data rate
20 MHz
11b: 1, 2, 5.5 and 11 Mbps
11g: 6, 9, 12, 18, 24, 36, 48, 54 Mbps
11n: MCS0-7, 72.2 Mbps (Max)
40 MHz 11n: MCS0-7, 150 Mbps (Max)
Antenna type PCB antenna, IPEX antenna
Note:
1. Device should operate in the center frequency range allocated by regional regulatory authorities. Target center
frequency range is configurable by software.
2. For the modules that use IPEX antennas, the output impedance is 50 Ω. For other modules without IPEX antennas,
users do not need to concern about the output impedance.
