MICROCHIP MRF24WG0MB-I/RM

The MRF24WG0MA and MRF24WG0MB are low-power, 2.4 GHz, IEEE 802.11-compliant SMT modules that integrate all associated RF components, including a crystal oscillator, bypass and bias passive components, and an integrated media access controller, baseband, RF, and power amplifier, with built-in hardware support for AES and TKIP (WEP, WPA, WPA2 security). The module design eliminates the need for RF and antenna design tasks and regulatory compliance testing, ultimately accelerating time-to-market. The MRF24WG0MA module is certified for use with an integrated PCB trace antenna. The MRF24WG0MB module features a U.FL connector and is certified for use with a range of antenna types that have passed module certification.
