MRF24J40MA

2.4 GHz IEEE Std. 802.15.4™ RF Transceiver Module

The MRF24J40MA is a 2.4 GHz IEEE Std. 802.15.4™ compliant, surface mount module with integrated crystal, internal voltage regulator, matching circuitry and PCB antenna. The MRF24J40MA module operates in the non-licensed 2.4 GHz frequency band and is FCC, IC and ETSI compliant. The integrated module design frees the integrator from extensive RF and antenna design, and regulatory compliance testing, allowing quicker time to market. The MRF24J40MA module is compatible with Microchip’s ZigBee®, MiWi™ and MiWi P2P software stacks. Each software stack is available as a free download, including source code, from the Microchip web site. The module connects to hundreds of PIC® microcontrollers via a 4-wire SPI interface and is an ideal solution for wireless sensor networks, home automation, building automation, and consumer applications.

Based on the MRF24J40 IEEE 802.15.4 transceiver there are further module versions available with higher TX power and UFL connector for applications which require a longer range.
