MICROCHIP MRF24WB0MB/RM

The MRF24WB0MA and MRF24WB0MB are low-power, 2.4 GHz, IEEE 802.11-compliant, surface mount modules with all associated RF components such as crystal oscillator, bypass and bias passives with integrated MAC, baseband, RF and power amplifier, and built-in hardware support for AES, and TKIP (WEP, WPA, WPA2 security). The integrated module design frees the designer from RF and antenna design tasks and regulatory compliance testing, ultimately providing quicker time to market. The MRF24WB0MA module is approved for use with the integrated PCB meander antenna. The MRF24WB0MB has an ultra miniature coaxial connector (U.FL) and is approved for use with a list of pre-certified antennas. The MRF24WB0MA/MRF24WB0MB modules are designed to be used with Microchip’s TCP/IP software stack. The software stack has an integrated driver that implements the API that is used in the modules for command and control, and for management and data packet traffic.
