MRF89XA-I/MQ

RF Transceiver ICS Overview

The MRF89XA-I/MQ is a single-chip, multi-channel FSK/OOK transceiver from Microchip Technology designed for Sub-GHz applications. It operates within the 863-870 MHz, 902-928 MHz, and 950-960 MHz license-free ISM bands. The device supports a maximum data rate of 200 kb/s and features an SPI serial interface. Key electrical parameters include a sensitivity of -113 dBm, a transmit output power of 12.5 dBm, and supply voltage range of 2.1V to 3.6V. Current consumption is specified at 3 mA during reception and 16 mA to 25 mA during transmission. It is housed in a 32-VFQFN (5x5 mm) package with exposed pad.

RF Transceiver ICS Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) prior to assembly. Ensure storage conditions adhere to pre-soldering guidelines to maintain reliability. Cross-reference ordering part numbers with specific suffixes to confirm package type and temperature grade alignment with design requirements.

RF Transceiver ICS Selection Notes

Select this component for designs requiring Sub-GHz ISM band operation with low power constraints. Verify that the required data rate does not exceed 200 kb/s and that the operating environment falls within the -40°C to 85°C range. Ensure the host system provides adequate voltage regulation within the 2.1V to 3.6V window. Confirm PCB layout compatibility with the 32-VFQFN footprint and thermal pad requirements.

RF Transceiver ICS Part Context

The MRF89XA-I/MQ belongs to the MRF89XA family of RF transceivers, which are engineered for cost-effective, low-power wireless solutions. This specific variant denotes the industrial temperature grade (-40°C to 85°C) and the MQ package style.
