DEVICE OVERVIEW

The MRF24J40MD/ME is a 2.4 GHz IEEE Std. 802.15.4™ compliant, surface mount module with integrated crystal, internal voltage regulator, matching circuitry, Power Amplifier (PA), Low Noise Amplifier (LNA) with PCB Trace Antenna (MRF24J40MD) or 50Ω external antenna connector (MRF24J40ME). The MRF24J40MD/ME module operates in the nonlicensed 2.4 GHz frequency band. The integrated module design frees the integrator from extensive RF and antenna design, and regulatory compliance testing allowing quicker time to market.
