Device Overview

Summary

The MRF49XA is a fully integrated Sub-GHz RF transceiver.  It supports FSK modulation with FHSS capability and is ideal for two-way, short-range wireless applications.  This low-power single chip Frequency Shift Keying (FSK) baseband transceiver supports Zero-IF architecture, Multi-channel and multi-band, Synthesizer with PLL, Power Amplifier (PA), Low Noise Amplifier (LNA), I/Q down converter mixers, I/Q demodulator, Baseband filters (BBFs) and amplifiers.  The MRF49XA is an ideal choice for low-cost, high-volume, low data rate (<256 kbps), two-way and short range wireless applications.  This transceiver can be used in the unlicensed 433 MHz,868 MHz and 915 MHz frequency bands, and for applications looking for FCC, IC or ETSI certification in the ISM band
