MRF24WG0MA-I/RM is an agency certified IEEE 802.11 b/g WiFi radio transceiver module. The MRF24WG0MA has an integrated PCB antenna, matching circuitry, and supports WiFi with the free TCP/IP protocol stack. The MRF24WG0MA module connects to hundreds of PIC microcontrollers via a 4 wire SPI interface. The MRF24WG0MA is a low power, 2.4GHz, IEEE 802.11-compliant, surface mount modules with all associated RF components like 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 modules also provide acceleration for hosts running WPA-EAP application 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 MRF24WG0MA module is approved for use with the integrated PCB meander antenna.
