Ideal for bi-directional, short-range wireless applications; provides cost-effective, easy integration with PIC MCUs

The Microchip Technology MRF49XA is a fully integrated Sub-GHz RF transceiver supporting the 434/868/915MHz ISM frequency band and FSK modulation with FHSS capability. The Microchip Technology MRF49XA is ideal for two-way, short-range wireless applications, and is easy to integrate with any Microchip 8-, 16-, or 32-bit PIC® MCU. The MRF49XA RF transceiver is also available on a PICtail™ / PICtail Plus daughter board for easy integration with the 8-bit PIC18 Explorer and 16-/32-bit Explorer 16 modular microcontroller development boards.
